LOCK OFF |
|
|
Indicates slow YTO tuning. This message may appear if the analyzer is using default correction factors. f LOCK OFF appears briefly during the CAL FREQ routine, during instrument preset, or when the frequency value is changed; this is normal and does not indicate a problem.
|
|
ADC-GND FAIL |
|
|
During an instrument preset, the analog-to-digital converter reading for ground on the A16 Processor/Video assembly is outside the test limit. An instrument preset routine is also performed during the self-calibration routines.
|
|
ADC-TIME FAIL |
|
|
During an instrument preset, the time between analog-to-digital conversion readings is greater than the test limit. An instrument preset routine is also performed during the self-calibration routines.
|
|
ADC-2V FAIL |
|
|
During an instrument preset, the analog-to-digital converter reading for the +2 V reference on the A16 Processor/Video assembly is outside the test limit. An instrument preset routine is also performed during the self-calibration routines.
|
|
CAL: DATA NOT STORED |
|
|
The current correction-factor data is the default calibration data. The instrument firmware prevents the default data from being stored. While the default data is in use, a flag is set. If CAL STORE is pressed, the error message is displayed and CAL STRORE is disabled. Successful completion of the, CAL AMPTD routine clears the flag.
|
|
CAL: cannot execute CALAMP |
|
|
The preamplifier gain is not set to 0 dB. The preamplifier gain must be set to 0 dB for the CAL AMPTD routine to be performed.
|
|
CAL: FM SPAN SENS FAIL |
|
|
During the CAL FREQ self-calibration routine the analyzer cannot set the span sensitivity of the FM coil. The output of the fine-tune DAC, located on the A 7 Analog Interface assembly, is changed to move the displayed signal four divisions. If the signal does not move to within ± 1.25 divisions of the expected display position, the error message is displayed.
|
|
CAL: GAIN FAIL |
|
|
During the CAL AMPTD routine, the amplitude of the video signal at the ADC on the A16 Processor/Video assembly is too low. The error message appears when the reference-level-calibration DAC, located on the A7 Analog Interface assembly, has been adjusted to its maximum of 255, and the amplitude of the video signal remains below tolerance.
|
|
Cal harmonic >= 5.7 GHz NOT found |
|
|
Indicates that the CAL YTF routine for an 8595E cannot find a harmonic of the 300 MHz calibration signal.

|
During the CAL AMPTD routine, the insertion loss of a resolution bandwidth filter, relative to the amplitude of the 3 kHz resolution bandwidth filter, was greater than 2.2 dB.
|
|
CAL SIGNAL NOT FOUND |
|
|
During a self-calibration routine, the CAL OUT signal cannot be found. The primary purpose of the CAL OUT check is to confirm that CAL OUT is connected to the input. A CAL OUT signal that is not within 300 MHz ±50 MHz, or is not greater than or equal to -45 dBm, causes this error message to be displayed.
|
|
CAL: SPAN SENS FAIL |
|
|
During the CAL FREQ self-calibration routine the main-coil span-sensitivity adjustment routine has failed, indicating that the spans controlled by the main coil (LO spans greater than 10 MHz) are not working correctly. The span-sensitivity adjustment routine checks for three displayed signals: 0 Hz, 300 MHz, and 600 MHz. If three signals are not found in a 750 MHz span, the error message is displayed.
|
|
CAL YTF FAILED |
|
|
Indicates that the CAL YTF routine could not be successfully completed.
|
|
CAL: ZERO FAIL |
|
|
The analyzer could not set up the tuning sensitivity of the main coil.

|
|
Indicates that the CAL YTF routine for the analyzer cannot find a harmonic of the comb generator at frequency displayed.
|
|
COMB SIGNAL NOT FOUND |
|
|
This message applies to 8592L, 8593E, 8596E model analyzers only.
|
|
CONF TEST FAIL |
|
|
Indicates that the confidence test failed. If this happens, ensure that the CAL OUT connector is connected to the analyzer input, perform the CAL FREQ & AMPTD routine, and then perform the confidence test again. This message also sets SRQ 110.
|
|
FAIL: XXXX XXXXXXXXXX |
|
|
A circuit-test failure was detected by the central processing unit (CPU) during power-up or instrument preset. A failure code has two major parts: a 4-digit code followed by a lO-digit code. The lO-digit code contains three separate failure codes. Each failure code must be converted from hexadecimal to binary before it can be interpreted,
|
|
FREQ UNCAL |
|
|
The YTO (YIG-tuned oscillator) frequency is more than 20 MHz from the desired frequency. If the FREQ UNCAL message appears constantly, it indicates a YTO-tuning error and the CAL FREQ routine should be performed. FREQ UNCAL appears briefly during the CAL FREQ routine; this is normal and does not indicate a problem.
|
|
Gate card not calibrated |
|
|
This message can indicate that either the CAL AMPTD routine need to be performed before the time-gating functions can be used, or that something was connected to the GATE TRIGGER INPUT connector during the CAL AMPTD or CAL FREQ & AMPTD routines.
|
|
INVALID CARD: BAD MEDIA |
|
|
Indicates the formatting routine (FORMAT CARD) for the memory card could not be completed. See the description for INVALID CARD above for more information about the possible causes of this message.

|
|
POS-PK FAIL |
|
|
The positive-peak-detector check has failed during the confidence test routine, CONF TEST The level of the noise floor for the positive-peak detector is statistically compared to that of the sample detector. The mean of the data from the positive-peak detector should be greater than the mean of the data from the sample detector.
|
|
REF UNLOCK |
|
|
The oscillator on the A9 third converter is not locked to a 10 MHz frequency reference. The analyzer must be connected to one of the following frequency references.
|
|
|
• 10 MHz standard timebase. The reference is a room-temperature crystal oscillator (RTXO) that is located on the A25 assembly.
|
|
|
• Precision frequency reference. The reference is a oven-controlled crystal oscillator (OCXO).
|
|
|
• External 10 MHz frequency reference.
|
|
RES-BW SHAPE FAIL |
|
|
During the confidence test routine, CONF TEST, the 3 dB bandwidth of a resolution bandwidth was not within 20% of its nominal value. The 10 kHz, 30 kHz, 100 kHz, 300 kHz, 1 MHz, and 3 MHz bandwidths are checked and the bandwidths that fail are displayed.
|
|
RES-BW NOISE FAIL |
|
|
During the confidence test routine, CONF TEST, the noise floor level was too high for the indicated resolution bandwidth. Starting with the widest resolution bandwidth, the test compares the noise floor amplitude of each bandwidth to the noise floor amplitude of the next, narrower resolution bandwidth. If a decrease in noise-floor amplitude does not occur, the test displays the narrower bandwidth as a test failure.
|
|
RF PRESEL ERROR |
|
|
Indicates that the preselector peak routine cannot be performed. For 8592L, 8593E, 8595E, and 8596E spectrum analyzers only.
|
|
RF PRESEL TIMEOUT |
|
|
Indicates that the preselector peak routine cannot be performed.
|
|
SAMPLE FAIL |
|
|
During the confidence test routine, CONF TEST, the sample-detector test has failed. The test makes a statistical comparison between the peak-to-peak amplitude of the noise floor for the positive-peak detector and the noise floor for the sample detector. The error message is displayed if the standard deviation of the data for the sample detector is less than the standard deviation of data for the positive-peak detector.
|
|
SMPLR UNLCK |
|
|
Indicates that the sampling oscillator circuitry is not functioning properly.
|
|
STEP GAIN/ATTEN FAIL |
|
|
During the confidence test routine, CONF TEST, the step-gain switching check has failed. Looking at displayed noise, the test steps the reference level from -60 dBm to +30 dBm, in 10 dB increments, with the input attenuator set to 60 dB. The error message is displayed if the noise level does not increase for each 10 dB step in reference level.
|
|
TG UNLVL |
|
|
This message can indicate the following: that the source power is set higher or lower than the analyzer can provide, that the frequency span extends beyond the specified frequency range of the tracking generator, or that the calibration data for the tracking generator is incorrect. See the 8590 E-Series and L-Series Spectrum Analyzers User's Guide for more information.
|
|
VID-BW FAIL |
|
|
During the CONF TEST routine the video bandwidth check has failed. The test checks for a decrease in the peak-to-peak excursion of the noise trace as the video bandwidth is decreased.
