Keysight (Agilent HP) 8590B Repair Service

8590B spectrum analyzer 10kHz-1.5GHz
Need your HP 8590B Spectrum Analyzer repaired or calibrated? Our veteran-owned lab handles both, with free estimates and quick turnaround.
The HP 8590B model offers basic RF and microwave measurement performance. You can change the test capabilities of these spectrum analyzers to fit specific measurement needs. The memory card reader enables you to load specific measurement personalities for cable television, electromagnetic compatibility, or digital radio applications. Complex measurement routines and test limits are available at a keystroke. The tracking generator provides a synchronously swept signal source for stimulus-response.

Any failures or unforeseen issues identified during the calibration phase will be detailed in an estimate submitted for your approval prior to any further action. Repair charges are determined by the actual time and materials required. Please be aware that customers are responsible for all associated shipping costs, to and from our location. This initial estimate is provided free of charge.

HP 8590B Error Messages

The HP 8590B spectrum analyzer (10 kHz to 1.5 GHz) shows text messages on screen when something is wrong. Each is marked (H) hardware, (U) user/setup, or (M) information.

First step: connect CAL OUT to the input and run CAL FREQ & AMPTD, then press CAL STORE. A hardware (H) message that comes back after a good self-cal means the 8590B needs repair.

8590B notes

  • The 8590B has no YIG-tuned filter, so CAL YTF and comb messages do not apply.
  • Memory card commands on the 8590B need Option 003; without it they return INVALID CARD.
  • With Option 010 (50 ohm) or 011 (75 ohm) tracking generator, TG UNLVL and TG SIGNAL NOT FOUND can appear.
  • SRQ numbers on the 8590B screen are service requests: SRQ 110 means hardware broken, SRQ 140 means an illegal command.

8590B hardware messages

MessageTypeMeaning
ADC-GND FAILHThe processor board failed its analog-to-digital converter ground check.
ADC-TIME FAILHThe processor board failed its analog-to-digital converter timing check.
ADC-2V FAILHThe processor board failed its analog-to-digital converter 2 V reference check.
FAIL: xxxx xxxxxxxxxxHA 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 UNCALU/HYTO 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 FOUNDU/HThe 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 FAILHSignal level too low during CAL AMPTD.
CAL: SPAN SENS FAILHThe span sensitivity calibration failed.
CAL: FM SPAN SENS FAILHCould not set the FM coil span sensitivity.
CAL: RES BW AMPL FAILHThe relative loss of a resolution bandwidth filter is wrong.
CAL: DATA NOT STORED CAL AMP NEEDEDU/HCorrection factors are corrupt and cannot be stored. Run CAL FREQ & AMPTD, then CAL STORE.
CAL: cannot execute CALAMP enter: 0 dB PREAMP GAINU/HSet EXT PREAMP gain to 0 dB before running CAL AMPTD.
CONF TEST FAILHThe confidence test failed.
POS-PK FAILHPositive-peak detector failed.
SAMPLE FAILHSample detector failed.
VID-BW FAILHVideo bandwidth check failed.
RES-BW NOISE FAILHNoise floor too high at the bandwidth shown.
RES-BW SHAPE FAILHA resolution bandwidth 3 dB width is out of specification.
STEP GAIN ATTEN FAILHIF step gain failed.

8590B calibration, setup and information messages

MessageTypeMeaning
CAL: USING DEFAULT DATAMCal data is corrupt, so default correction factors are in use. An interrupted self-cal can cause this.
MEAS UNCALUSweep time, span and bandwidth settings make the measurement uncalibrated.
CAL: PASSCODE NEEDEDMThe function needs the service passcode (center frequency −37 Hz).
SRQ 110MHardware broken service request. Look for the hardware message shown with it.
SRQ 140MIllegal command was received over the bus.
INVALID SYMTAB ENTRY: SYMTAB OVERFLOWUToo many user-defined items or downloadable programs in memory; delete some with DISPOSE USER MEM. It can also mean a failed processor board.
CAL: NO YTF IN 8590/1UThe CAL YTF command does not apply to the 8590B; it has no YIG-tuned filter.
NO COUNTERLOCK AVAILABLEUThat command needs the counter-lock hardware, which the 8590B does not have (8591A and 8593A only).
TG UNLVLUTracking generator power set beyond what it can provide (Option 010 or 011).
TG SIGNAL NOT FOUNDUTracking generator output not found; check the cable from RF OUT to the input.

8590B 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.
