Agilent E5070B Error Messages
This E5070B list covers the on-screen errors that matter for repair and the board each one leads to. Errors show on a red bar at the lower left; numbered ones can be read over GPIB.
E5070B notes
- The E5070B runs a power-on self test at every start; a failure is reported as error 241 and broken down by the internal test in the service menu.
- If the rear fan does not run, the A50 power supply is suspect; check the +3.3 V / +5 V monitor LEDs on the A21 board.
E5070B hardware errors
| Error | Message | Meaning |
|---|---|---|
| 220 | Phase lock loop unlocked | A synthesizer PLL lost lock during measurement. The service manual points to the A1 source board. |
| 241 | Power on test failed | The power-on self test found a hardware fault. Run the internal test from the service menu; the first failed test identifies the board (A1 source, A2 receiver (A15 RF / A17 IF boards), A3 level vernier, A4 power amp, A6 switch/temperature control, A7 attenuator). |
| 240 | Calibration data lost | The system calibration file is missing or damaged at startup. The analyzer needs its adjustment data restored or regenerated. |
| 221 | Port 1 receiver overload | Too much power into port 1. If it appears with nothing connected, the analyzer is faulty. |
| 222 | Port 2 receiver overload | Same as 221 for port 2. |
| 223 | Port 3 receiver overload | 3- and 4-port options only. |
| 224 | Port 4 receiver overload | 4-port options only. |
| 61 | Power unleveled | Requested output power is outside the leveling range after correction. |
| 60 | Continuous switching may damage source attenuator | Different source power ranges on several channels keep the attenuator switching (Options 214/314/414). Not a fault, but wears the A7 attenuator. |
| — | Fatal Error: Failed to Initialize DSP / DSP Driver | The A21 analog interface board or A20 digital motherboard did not start. Also shown after a failed firmware update. |
| — | Fatal Error: Failed to Update DSP Code | Writing DSP firmware to flash on the A21 analog interface board failed; reinstall firmware, then suspect A21 analog interface board or A20. |
