HP / Agilent 8753ES Error Messages – click to expand
HP / Agilent 8753ES Error Messages
When the HP / Agilent 8753ES S-parameter network analyzer (30 kHz to 3 GHz (6 GHz with Option 006)) detects a problem, it shows a message and an error number on screen. These are the service-related messages from the 8753ES service guide, explained in plain language.
8753ES notes
- The 8753ES has a built-in S-parameter test set (transfer switch, two test port couplers and R, A and B samplers).
- Option 006 extends the 8753ES to 6 GHz; Option 075 changes it to 75 ohm test ports.
- Phase lock errors on the 8753ES usually point to the source (YIG oscillator or source assembly) or the phase lock board, but check R channel input level first.
8753ES hardware error messages
| Message | Error no. | Type | Meaning |
|---|---|---|---|
| NO IF FOUND: CHECK R INPUT LEVEL | 5 | H | The first IF was not detected while pretuning the phase lock. Usually a source fault, or the R channel is getting too little signal (needs at least −35 dBm). |
| NO PHASE LOCK: CHECK R INPUT LEVEL | 7 | H | The IF was found during pretune but the loop never locked. Check R channel level, then the source and phase lock circuits. |
| PHASE LOCK LOST | 8 | H | Phase lock was acquired and then dropped during the sweep. |
| PHASE LOCK CAL FAILED | 4 | H | The automatic phase lock calibration (run at power-on or when pretune drifts) failed. |
| POSSIBLE FALSE LOCK | 6 | H | The source may be locked to the wrong harmonic comb tooth, so frequencies can be wrong. |
| SWEEP TIME TOO FAST | 12 | H | The fractional-N and digital IF circuits lost synchronization; points to the digital control section. |
| POWER UNLEVELED | 179 | H | Source output is not leveled. Can be a power setting beyond the source range or a source/ALC fault. |
| POWER SUPPLY HOT! | 21 | H | The power supply is overheating. Check the fan, filter and air flow. |
| POWER SUPPLY SHUT DOWN! | 22 | H | One or more supplies shut down, usually from an overload or short on a board. |
| PROBE POWER SHUT DOWN! | 23 | H | The front-panel probe power supply shut down from a short or overload. |
| BATTERY FAILED. STATE MEMORY CLEARED | 183 | H | The memory backup battery has failed and stored instrument states were cleared. Replace the battery on the CPU board. |
| BATTERY LOW! STORE SAVE REGS TO DISK | 184 | H | The memory backup battery is getting weak. Save your states to disk and replace the battery. |
| CORRECTION CONSTANTS NOT STORED | 3 | H | Writing correction constants to EEPROM failed. The A9 CPU write-protect switch/jumper must be set to allow writing. |
| DEADLOCK | 111 | H | An internal firmware deadlock occurred. Cycle power; if it repeats, the CPU or a firmware problem is likely. |
| DISK HARDWARE PROBLEM | 39 | H | The disk drive is not responding properly. |
| DISK READ/WRITE ERROR | 189 | H | A disk read or write failed; try another disk, then suspect the drive. |
| DISK MESSAGE LENGTH ERROR | 190 | H | The disk drive and analyzer are out of step during a transfer. |
| INITIALIZATION FAILED | 47 | H | The disk could not be initialized; check the disk and drive. |
8753ES calibration, setup and information messages
| Message | Error no. | Type | Meaning |
|---|---|---|---|
| OVERLOAD ON INPUT R, POWER REDUCED | 57 | U | Too much power at the R input; source power was reduced (P⇓). |
| SOURCE POWER TURNED OFF, RESET UNDER POWER MENU | M | An input overload tripped the source off. Remove the overload and turn power back on in the power menu. | |
| CALIBRATION REQUIRED | 63 | U | No calibration set matches the current stimulus or measurement; perform a new cal. |
| CURRENT PARAMETER NOT IN CAL SET | 64 | U | The parameter you selected was not included in the active calibration. |
| CORRECTION TURNED OFF | 66 | U | Sweep type, start, span or number of points changed from the cal, so correction was switched off. |
| NO CALIBRATION CURRENTLY IN PROGRESS | 69 | U | A cal step was requested but no calibration is running. |
| NO SPACE FOR NEW CAL. CLEAR REGISTERS | 70 | U | Memory is full; clear saved registers to store a new calibration. |
| CALIBRATION ABORTED | 74 | U | The active channel was changed during a cal, so it stopped. Restart on the right channel. |
| WRONG DISK FORMAT, INITIALIZE DISK | 77 | U | The disk is not in LIF format; initialize it before use. |
| TROUBLE! CHECK SETUP AND START OVER | 115 | U | The test equipment setup for an adjustment is not correct; check the setup diagram. |
| TEST ABORTED | 113 | U | A service test or adjustment was stopped before it finished. |
| POWER METER INVALID | 116 | U | The power meter reading is out of range or not valid. |
| PWR MTR: NOT ON/CONNECTED OR WRONG ADDRS | 117 | U | The power meter is off, not connected by GPIB, or set to the wrong address. |
| POWER METER NOT SETTLED | 118 | U | Power meter readings are not stable. |
| NOT ALLOWED DURING POWER METER CAL | 198 | U | That function cannot be used while a source power meter calibration is running. |
| INSUFFICIENT MEMORY, PWR MTR CAL OFF | 154 | U | Not enough memory for power meter cal data, so it was turned off. |
| SAVE FAILED. INSUFFICIENT MEMORY | 151 | U | Not enough memory to save the state; clear some registers. |
| NOT ENOUGH SPACE ON DISK FOR STORE | 44 | U | The disk is full. |
| NO FILE(S) FOUND ON DISK | 45 | U | No files of the requested type are on the disk. |
| PARALLEL PORT NOT AVAILABLE FOR COPY | 167 | U | The parallel port is set for GPIO, so it cannot be used for printing. |
| PARALLEL PORT NOT AVAILABLE FOR GPIO | 165 | U | The parallel port is set for printing, so it cannot be used as GPIO. |
| SWEEP MODE CHANGED TO CW TIME SWEEP | 187 | M | The sweep mode was switched to CW time sweep. |
