I got a HP 8664A for free. It gives error messages "Hardware failure 5", "Calibration error 1" and "Calibration error 2. Does anyone have experience in debugging and fixing these? |
| Tony_G:
Hardware Failure 5 is in the ALC. The result code of 8,043,311 is a calibration error code (hence the Cal Error messages) - The manual suggests running the ILD (Instrument Level Diagnostic) test function to get a full error result. * INSTR PRESET * SPECIAL * 3,2,0 * SPEACIAL * If the display says "320 Test" then press ENTER (ON) * Otherwise rotate the RPG Knob until "320 Test" is displayed and then press ENTER(ON) This is in section 2 of the service manual on the Keysight web. |

Thanks, I'll try this. |

I had to open the top lid and enable "Service Special Function" DIP switch. After that the "320 Test Instrument" worked. The result code was -10,124,311. I have to disconnect the HF DRVR - J6 connector and connect the cable to the power meter for further debugging (Test 2A). To be continued tomorrow..... |
