Each drum read and wrote 50 bits at a time in parallel so transferring data could be done quickly. The drums were organized as 17 fields with 8192 words per field for a total capacity of 139264 words. The motors that rotated the drums required 208 VAC at 45 Hz so a motor generator unit was required to change the frequency from 60 Hz. This added to the noise level in the computer room.General Histories (Report). Office of Air Force History.USAF Hist Div Liaison Ofc.

On the FSQ 7 memory 1 had 65,536 words and memory 2 had 4096 words. At Luke Air Force Base, the FSQ-7 held 65,536 words at each bank and the FSQ-8 4096 words at each bank.Arithmetic operations were performed on both halves simultaneously. Each number was treated as a fraction between ?1 and 1. This restriction is placed on data primarily so that the multiplication of two numbers will always result in a product smaller than either of the numbers, thus positively avoiding overflow. Properly scaling calculations was the responsibility of the programmer.The remainder of the left half word specified the operation. The first three bits after the sign specified an index register.

Each user was given a priority-based time slice, measured in milliseconds, when the user's program was written from the magnetic drums into much higher speed memory, processed, and then written back to the magnetic drums with any computational changes that had occurred.The address consisted of 18 bits (3 bytes) for the memory address, with other bits used for the specification of index registers and indirect addressing. The operation field provided the operation code and a variety of modifiers. Some modifiers allowed instructions to operate only on specific bytes of a word or on specific bits of a byte without separate masking operations. Other modifiers allowed the single 48-bit ALU to operate on a pair of 24-bit operands to facilitate vector operations.Each word was divided into eight 6- bit bytes. A 6-bit byte, as opposed to the 8-bit byte in common use today, was common in IBM and other scientific computers of the time. The address space provided a maximum of 256K words. The prototype was equipped with 128k words (48 bits plus two parity bits ) of memory that was oil and water cooled. Also considered as part of the memory subsystem in that they were addressed via fixed reserved memory addresses, were 4 48 position switch banks, in which a short program could be inserted, and a plug panel, similar to the one used in IBM Unit-Record equipment, that had the capacity of 32 words, so longer bootstrap or diagnostic programs could be installed in plug panels which could then be inserted into the receptacle and used as a primitive ROM.

If the voltage is supplied, the error is probably located on the module removed. Note: The power supply switches off all voltages after a short time in the case of a short-circuit. After successful initialization of the computer, the Windows XP operating system starts up. Subsequently, the test application is loaded as a start-up program. Simultaneously, selftests are performed at various locations and error messages, if any, are output. The messages are disabled with normal operation, but can be enabled for troubleshooting purposes. When troubleshooting, it is advisable to connect a keyboard to the keyboard socket. The test results are usually not displayed. If errors occur during the boot procedure, these messages may indicate defects. The keystroke is acknowledged by a second beep. Then, all messages are displayed.

It contains all information required for repairing the FSQ by the replacement of modules. The service manual comprises four chapters and an annex (chapter 5) containing the FSQ circuit documentation: Chapter 1 provides all the information necessary to check for compliance with rated specifications. The required test equipment is included, too. Chapter 2 describes the manual adjustment of the calibration source and of the frequency accuracy as well as the automatic adjustment of individual module data following module replacement. Chapter 3 describes the design as well as simple measures for repair and fault diagnosis, in particular, the replacement of modules. Chapter 4 contains information on the extension instrument software and retrofitting options. Chapter 5 describes the shipping of the instrument and ordering of spare parts and contains spare parts lists and exploded views.For introduction typical measurement tasks are explained in detail using the functions of the user interface and program examples. The calibration documentation consists of the DKD calibration certificate. In the following sections, the procedures for checking the rated specifications are described. The data is given in the specification. The values must be extended by the tolerance of the measurement equipment used in this performance test. Power supply starts, screen remains dark.

Service Level 1 - Test Following the Entry of a Password When entering the password, the test result is recorded in detail and, in case of a fatal error (such as a failure of the operating voltage), the selftest is not aborted. The selftest can be called in the SETUP - SERVICE menu: SETUP REFERENCE INT EXT NOISE SRC ON OFF INPUT RF INPUT CAL SELFTEST SELFTEST RESULTS Enter the password 894129 with ENTER PASSWORD. Initiate the selftest of the instrument modules using the SELFTEST softkey. While the selftest is running, a message box is displayed that shows the current test and test result. Pressing ENTER ABORT aborts the test run. GENERAL SETUP SYSTEM INFO SERVICE ENTER PASSWORD SELFTEST RESULTS All modules are tested one by one and the test result (selftest PASSED or FAILED) is output in the message box The SELFTEST RESULTS softkey calls a complete list of all test results. If an error occurs, a brief description of the failed test, the module concerned, the valid range and the measurement value are displayed. These entries indicate that a test item was not carried out, because the conditions had not been met. In this case, an error is present only if the instrument cannot be calibrated. The selftest with password returns FAILED as the overall status, because the instrument will no longer be able to be calibrated in the near future due to temperature drift or aging. This is always tested when the instrument is switched on. The analog test signal is provided by the preceding analog tests. Since the operating voltages are measured first, it is ensured that the selftest can be performed correctly. If an operating voltage not required by the selftest has failed, this is correctly signaled in the error list. The test is not aborted after entry of the password. All subsequent errors are then listed in the result record. Errors that have occurred irrespective of the voltage failure can then still be detected.

The error message indicates the error source (power supply, IF filter, wideband detector unit) and the voltage that has failed. Selftest aborted. If error messages occur, the voltages on the motherboard should be checked. If the voltages are within the tolerance limits, the error must be located in the selftest: Replace the wideband detector unit. Regulated voltages on the boards Wideband detector unit Channel Nominal voltage 6 -5V FATAL ERROR. Detector: DC FAIL -5V. Check the temperature data for plausibility. The fan might be defective or the ventilation slots might be covered. Subsequently the operating voltages are measured. If, in the following, the first operating voltage (or all operating voltages after entering the password) is measured incorrectly, the selftest will obviously be defective. The voltage of the temperature sensor is used for temperature compensation of the filters. The other ones are provided for options (microwave converter, tracking generator).

Press ENTER to choose. Seconds until highlighted choice will be started automatically: 0 For troubleshooting and advanced startup options for Windows, press F8. While booting, the wideband detector unit is identified again. A timer which is controlled by a 32 MHz clock signal is set on the detector board. If there is an error on the detector board or the clock is missing, the following message is displayed: SYSTEM MESSAGE DETECTOR:Access failed, check HW component. OK After passing the function tests, the analog boards are initialized and the correction data EEPROMs are loaded. The reference is generated on the synthesizer. This 128 MHz reference is necessary for proper functioning of the detector board. Measurement: In this case, first check the clock generation in the instrument. The following measurements are appropriate to check the reference supply: Result: No signal: Synthesizer A100, X114: rated value 128 MHz, 0 dBm replace synthesizer. Synthesizer A100, X114: No signal:replace rated value 32 MHz, 0 dBm synthesizer. Normal action Error and error cause On booting the instrument, all calibration data required must be written to the RAM of the computer. The calibration data of a module is either read from the EEPROM (in the case of a cold start from EEPROM only) or from the associated binary file. The module information is read from the module EEPROMs in the case of a cold start. Otherwise the binary data is read from the hard disk during starting (e.g. motherb.bin). If reading at the desired address is not possible, the software assumes that the module is not available. For modules that must always be available (e.g. IF filter), an error message will be output: Error reading EEPROM of IF Filter The calibration data are then read from the file pertaining to the module (e.g. motherb.bin). If the binary data cannot be read out without error, an error message will be output, e.g.

: Error reading file of IF Filter If reading at the address of an optional module is not possible, this module is marked as not available in the module array for storage of the module information. If the file pertaining to the non-available module does exist, it is assumed that upon the last successful booting the module was available but has been removed meanwhile. The file with the calibration data of the module is erased. Moreover, the data collected during the last calibration is invalid and only saved as a backup copy on the hard disk If reading at the address of a module is possible but the contents of the data block are faulty (e.g. check sum of header block incorrect), the calibration data of the respective module is read from the associated file. The firmware assumes that the module is available. The information read from the file is entered into the array for storage of the module information. If the module header can be read from the file and complies with the header read from the EEPROM, the assumption is made that the contents of the module EEPROM have already been mapped in the binary file. The calibration data can thus be written from the file to the RAM. If, however, the associated file cannot be found or if the module header of the EEPROM differs from that of the file, the total EEPROM contents must be written to the RAM and then saved in the binary file. Error finding file of IF Filter After loading the calibration data from the EEPROMs, the calibration data are loaded from the calibration data files (e.g. DDC settings for various filters). First the relevant calibration data file is written to the calibration data memory. All signal paths are connected and the signal is traced via test points. The selftest checks all possible hardware settings that are used for the self-calibration with regard to a sufficient setting range including reserves.

Replace synthesizer Calibration signal control voltage: Checking the detector voltage in the level control ERROR.In the case of a small level error, the selftest of the signal path is possible. However, the level measuring accuracy will be out of tolerance after instrument calibration. Temperature measurement: The RF Converter accommodates a temperature sensor for the module temperature. Test channel 67 WARNING. RF Converter: Temperature out of range Check air supply and fan for proper functioning. Test LO level The level detectors of the second and third LO are read: Channel Oscillator Expression displayed in the error message 3 LO 3 Level 3rd Local 2 LO 2 Level 2nd Local In the the voltage is too low, also check the level at the module input in the selftest poll. YIG oscillator test: The YIG oscillator is tuned throughout the entire frequency band. The pretuning (with upper and lower limit) is also tuned with a small offset from the actual frequency. If the current flowing through the YIG coil and set by the PLL reaches one of these limits, the unlock detector will respond. This is a test both for the pretuning values and for functioning of the PLL. FATAL ERROR! YIG Oscillator unlocked. The two voltages can be polled via the selftest channels 0 and 1. If the two voltages are missing or too low, the LO level is presumably missing, which is why an error message appears: FATAL ERROR! 1st LO level low or 1st mixer defective. FATAL ERROR! 1st Mixer symmetry out of tolerance. The first and second mixer feature sufficient LO power, i.e. the conversion from the RF to the second IF should therefore work properly. Normal action Error and error cause Signal path via RF attenuator The measurement is made at the second IF using a logarithmic detector on the RF converter. It is not likely that all attenuator stages and the 0-dB position are faulty; therefore, the following error message appears. FATAL ERROR! Input level RF converter out of tolerance.

Before replacing the RF converter, measure the input level at X108 in any case. For this purpose, the input is connected to the Cal source with 0 dBm and 0 dB attenuator DC coupling. The level should lie at 128 MHz and 0 dBm. Otherwise, check level at X125. If the level is okay, replace the RF converter. If the signal is not applied at the synthesizer either, replace the synthesizer. If only individual measurements are out of tolerance, the RF attenuator is defective. FATAL ERROR!. RF Attenuator xx dB pad failed. The selftest is not interrupted after entry of a password. The EEPROM data in the RF converter are obviously incorrect. LC filter I and XTAL filter The level measurement is performed with wide and narrow bandwidths of the LC filter. Subsequently, an additional measurement is performed via the crystal filter. If the LC filter does not work properly, the measurement of the crystal filter is not performed. The input level is attenuated in steps of 10 dB by the RF attenuator and simultaneously amplified by means of the StepGain by the same amount. FATAL ERROR! IF board: Step Gain Fine Selftest aborted Test with Step Gain Coarse bypassed (0 dB) and Step Gain Fine set to 0 dB. If an error occurs, Step Gain Fine does not work correctly or the signal path is interrupted. Replace the IF filter board. ERROR! IF board: Step Gain Coarse Testing the amplifier stages. ERROR! IF board: Step Gain Fine Testing the amplifier stages. Attention: If the RF attenuator test has already caused an error message, Step Gain cannot be tested and an error message must be ignored. If the RF attenuator test passed without any error, Step Gain is defective. However, the selftest can be continued since it does not require the IF gain. Signal Paths on Wideband Detector Unit Normal action Error and error cause Various settings of the wideband detector unit are checked via the normal display function, i.e. FFT mode, digital filters and analog filters. Possible error messages: ERROR.

Baseband input X145 (Q channel) is checked for continuity. For the I channel, this is done by switching to the IF path; for the Q channel by switching to GND. The typical value measured is 0 V. Compliance with -6 dBm (128 MHz). Since this mixer is directly connected to the input connector, it may be easily destroyed by the user. Action Error and error cause Measure with diode tester at X101: rated value: approx. 0.6 V voltage in the forward and reverse directions with a current of 1 mA. The function of this oscillator requires both the EEPROM data and the reference frequency of the second module. Action Measure function of the 1st LO in zero span. The center frequency of the FSQ must be set to the frequency of the signal generator, and the span must be set to 0 Hz. Check levels of the modules on the MW converter unit (see following items). If the measured level is within tolerances, the attenuator or a subsequent module in the signal path is defective. If the measured level is within tolerances, one of the subsequent modules on the MW converter is defective. Set the FSQ to the center frequency of the signal generator and a span of 0 Hz. If the instrument is operated on an adapter, the LO (connector X102 RF converter) must be taken out to the MW converter (connector X167). For example, the tests of the detector board signal path rely on a correct IF or video input signal. Part of the signal path is tested only functionally. For example, a blocked bit (except one of the most significant ones) cannot be detected, as there is no test pattern available from ADC. If the selftest has been passed but the instrument shows unexpected response in the spectrum display such as spikes, strong noise, pumping noise floor, spurious, stepped curves and so on, some additional tests should be performed to prove that the fault is actually in the detector unit. Test Setup Connect signal generator (50 output impedance) to X149 of the detector board.

Video Path, Differential Linearity Test This is a sensitive test for blocked bits. The instrument expects a logarithmic signal at the ADC input. In the test case, a linear signal is used instead at the ADC input. The firmware update kit contains several diskettes. The installation program is called up in the SETUP menu. Use the cursor keys to select the operating system to start within the boot menu (Analyzer Firmware Backup) from the backup partition and confirm with ENTER. Seconds until highlighted choice will be started automatically: 5 For troubleshooting and advanced startup options for Windows, press F8. After the operating system has been started from the backup partition, a window with various restore functions appears. The desired function can be started by entering the corresponding number. The operating system files will now be copied from the backup partition to the analyzer partition. After all files have been copied, the instrument boots and the firmware is installed. These mounting instructions can be inserted at this location in the service manual and will thus be available when needed. Caution! Disconnect the instrument from the mains before opening the casing. Also pay close attention to the safety instructions at the beginning of this manual. The components used in the instrument are sensitive to electrostatic discharges which is why they are to be handled in accordance with the ESD regulations. When installing hardware options, note the following. Switch off the instrument and pull the mains plug. ? Unscrew the 4 rear-panel feet (450) and push the tube (410) backwards and take off. ? After installing the option, replace the tube and screw the rear panel feet back on. The two protective caps for the front and rear panels prevent the control elements and connectors from being damaged. The antistatic packing foil avoids any undesired electrostatic charging to occur.

If you do not use the original packaging, provide for sufficient padding to prevent the instrument from slipping inside the package. Wrap antistatic packing foil around the instrument to protect it from electrostatic charging. Shipping of a Module When shipping a module, then, also be also careful to provide for sufficient mechanical and antistatical protection Ship the module in a sturdy, padded box. Wrap the board into antistatic foil. If the packaging is only antistatic but not conductive, additional conductive packaging is required. The additional packaging is not required if the enclosed packaging is conductive. Refurbished Modules Refurbished modules are an economic alternative for original modules. It should be kept in mind that refurbished modules are not new, but repaired and fully tested parts. They may have traces from use but they are electrically and mechanically equivalent to new modules. Taking back Defective Replaced Modules Defective modules of the replacement program which can be repaired are taken back within 3 months after delivery of the replaced module. A repurchasing value is credited. Excluded are parts which can not be repaired, e.g. PCBs that are burnt, broken or damaged by repair attempts, incomplete modules, parts which are heavily damaged mechanically. Important Note! When replacing a module please note the safety instructions and the repair instructions given in chapter 3 and at the beginning of this service manual When shipping a module be careful to provide for sufficient mechanical and antistatical protection.
