Agilent E8363B Error Messages
The E8363B messages below are the ones that point to hardware, followed by what a failed performance test means on this model.
E8363B on-screen error messages
| Message | Meaning and where to look |
|---|---|
| PHASE LOCK LOST | The A11 phase lock board sees too little reference-receiver signal to lock. Cause can be in the source, signal separation (couplers, switch) or receiver path. Check the A10 frequency reference output and the reference receiver first. |
| SOURCE UNLEVELED | On the E8363B check cables W37/W38 from the A23/A24 detectors to the A16 test set motherboard and W39 to the A21 SOMA 50. One port only: replace that port's detector. Both ports: replace A16. |
E8363B failed performance test – likely cause
| Failed test | What it points to |
|---|---|
| Source power accuracy / linearity | Run the source calibration adjustment; if it still fails, the source (A12 source) is suspect. |
| Source maximum power output | Follow the signal through the separation path (switch, couplers, attenuators) to find the loss. |
| Frequency accuracy | Measure the rear-panel 10 MHz REF OUT; more than about 10 Hz off calls for the 10 MHz reference adjustment. |
| Trace noise | Rarely fails alone; run the receiver calibration adjustment, then suspect the A6 SPAM board. |
| Receiver compression / noise floor / dynamic accuracy | Points to the A31–A34 receivers or the A6 SPAM board. Receivers are identical, so swapping two channels confirms a bad one. |
| Calibration coefficients | Tracking terms only: run the receiver calibration adjustment. Any other error term failing means a hardware fault. |
| System crosstalk | Loose RF cable, or isolation loss in the receivers or the receiver/test set motherboard. Tighten all cables and receiver screws first. |
SCPI error ranges
| Range | Class |
|---|---|
| −100 to −199 | Command errors |
| −200 to −299 | Execution errors |
| −300 to −399 | Device-specific errors |
| −400 to −499 | Query errors |
