HP 8592B Error Messages
If your HP 8592B (9 kHz to 22 GHz) is displaying a message on screen, this list explains it. (H) = hardware fault, (U) = user or setup error, (M) = information.
First step: connect CAL OUT to the input and run CAL FREQ & AMPTD and CAL YTF, then press CAL STORE. A hardware (H) message that comes back after a good self-cal means the 8592B needs repair.
8592B notes
- The 8592B has a YIG-tuned filter; run CAL YTF after CAL FREQ & AMPTD with the 100 MHz comb output cabled to the input.
- Memory card commands on the 8592B need Option 003; without it they return INVALID CARD.
- SRQ numbers on the 8592B screen are service requests: SRQ 110 means hardware broken, SRQ 140 means an illegal command.
8592B hardware messages
| Message | Type | Meaning |
|---|---|---|
| ADC-2V FAIL | H | The processor board failed its analog-to-digital converter 2 V reference check. |
| FAIL: xxxx xxxxxxxxxx | H | A circuit fault was found during the power-up self-test. The 4-digit and 10-digit code identifies the failed circuit (see the service manual). |
| FREQ UNCAL | U/H | YTO tuning failure. Common when default correction factors are in use; run CAL FREQ. It also flashes briefly during CAL FREQ or when turning the knob, which is normal. |
| CAL SIGNAL NOT FOUND | U/H | The CAL OUT signal could not be found. Check the cable from CAL OUT to the input. If it is connected, enter the −37 Hz passcode (FREQUENCY, −37, Hz) before CAL FREQ or CAL FREQ & AMPTD. |
| CAL: GAIN FAIL | H | Signal level too low during CAL AMPTD. |
| CAL: SPAN SENS FAIL | H | The span sensitivity calibration failed. |
| CAL: FM SPAN SENS FAIL | H | Could not set the FM coil span sensitivity. |
| CAL: RES BW AMPL FAIL | H | The relative loss of a resolution bandwidth filter is wrong. |
| CAL: DATA NOT STORED CAL AMP NEEDED | U/H | Correction factors are corrupt and cannot be stored. Run CAL FREQ & AMPTD, then CAL STORE. |
| CAL: cannot execute CALAMP enter: 0 dB PREAMP GAIN | U/H | Set EXT PREAMP gain to 0 dB before running CAL AMPTD. |
| CONF TEST FAIL | H | The confidence test failed. |
| POS-PK FAIL | H | Positive-peak detector failed. |
| SAMPLE FAIL | H | Sample detector failed. |
| VID-BW FAIL | H | Video bandwidth check failed. |
| RES-BW NOISE FAIL | H | Noise floor too high at the bandwidth shown. |
| RES-BW SHAPE FAIL | H | A resolution bandwidth 3 dB width is out of specification. |
| STEP GAIN ATTEN FAIL | H | IF step gain failed. |
| COMB SIGNAL NOT FOUND | U/H | The 100 MHz comb signal was not found. Check that COMB OUT is cabled to the input. |
| CAL: LOST COMB SIGNAL | U/H | Comb signal too weak to finish CAL YTF. Use a short, low-loss SMA-to-Type-N cable from the comb output to the input. |
| ADC-GND FAIL | H | The processor board failed its analog-to-digital converter ground check. |
| ADC-TIME FAIL | H | The processor board failed its analog-to-digital converter timing check. |
8592B calibration, setup and information messages
| Message | Type | Meaning |
|---|---|---|
| CAL: USING DEFAULT DATA | M | Cal data is corrupt, so default correction factors are in use. An interrupted self-cal can cause this. |
| MEAS UNCAL | U | Sweep time, span and bandwidth settings make the measurement uncalibrated. |
| CAL: PASSCODE NEEDED | M | The function needs the service passcode (center frequency −37 Hz). |
| SRQ 110 | M | Hardware broken service request. Look for the hardware message shown with it. |
| SRQ 140 | M | Illegal command was received over the bus. |
| INVALID SYMTAB ENTRY: SYMTAB OVERFLOW | U | Too many user-defined items or downloadable programs in memory; delete some with DISPOSE USER MEM. It can also mean a failed processor board. |
| NO COUNTERLOCK AVAILABLE | U | That command needs the counter-lock hardware, which the 8592B does not have (8591A and 8593A only). |
8592B remote programming and memory card messages (U)
These come from bad remote commands, memory card problems or bus setup, not hardware: COMMAND ERROR, PARAMETER ERROR, INVALID ITEM, INVALID VALUE PARAMETER, INVALID ENTER FORMAT, INVALID OUTPUT FORMAT, INVALID BLOCK FORMAT: IF STATEMENT, INVALID COMPARE OPERATOR, INVALID REPEAT MEM OVFL, INVALID REPEAT NEST LEVEL, INVALID ACTDEF, INVALID VARDEF, INVALID KEYNAME, INVALID AUNITS, INVALID DETECTOR, INVALID TRIGGER MODE, INVALID TRACE, INVALID TRACE NAME, INVALID REGISTER NUMBER, INVALID SAVEREG, INVALID STORE DEST, INVALID CHECKSUM: USTATE, INVALID AMPCOR: FREQ, INVALID WINDOW TYPE, CONFLICT TABLE OVERFLOW, CAL: NO YTO AVAILABLE, SOFTKEY OVFL, UNDEF KEY, TABLE FULL, INVALID HP-IB ADDRESS/OPERATION, INVALID HP-IB OPERATION REN TRUE, INVALID RS-232 ADDRESS/OPERATION, INVALID CARD, INVALID CARD: DIRECTORY / NO CARD / TYPE, INVALID FILE: NO ROOM, NO CARD FOUND.
