HP / Agilent 8563E Error Codes (ERR 100–922) – click to expand

HP / Agilent 8563E Error Codes

If your Agilent / HP 8563E (9 kHz to 26.5 GHz (30 Hz with Option 006)) is showing an ERR message in the lower-right corner, the code tells you which part of the analyzer is in trouble. Only one code shows at a time. Press RECALL, MORE 1 OF 2, RECALL ERRORS, then use the arrow keys to see the rest. Write them all down; the first hardware code is usually the root cause.

First step: save your state, press PRESET, CAL, REALIGN LO & IF and let it finish. If a code between 200 and 799 returns, the 8563E needs service.

8563E notes

  • The 8563E has a CRT display driven by a high-voltage module. A dim, blank or distorted screen usually has no ERR code at all.
  • FADC codes ERR 202–207 and ERR 760 only apply to an 8563E with Option 007 (fast digitized sweeps).
  • The 8563E input is DC coupled only, so a COUPLING command returns ERR 144. Any DC over 0.2 V on the input can damage the mixer, especially with Option 006.
  • Above 2.9 GHz the 8563E uses a YIG preselector. Bad stored preselector peak data shows as ERR 704; use FACTORY PRSEL PK to restore it.

400–599 IF errors – 8563E

These come from the automatic IF alignment. It aligns amplitude first, then the resolution bandwidths in this order: 300 kHz, 1 MHz, 2 MHz, 100 kHz, 30 kHz, 10 kHz, 3 kHz, 1 kHz, 300 Hz down to 1 Hz. Bandwidths aligned before the failure are usually still good; ones after it are suspect.
