Rohde & Schwarz SMIQ03B with Error 313, Error 180 Calibration failed and Erro183

[lcharman]

Hello

I have a R&S SMIQ03B with the error in the subject.
Four errors 313 Calibration memory lost shows;
1. - LEV PRESET, 2. - VECTOR MOD, 3. - LEV ATT and 4. - ALC OFF MODE = TABLE - run internal calibration
I perform the internal calibration.  3 Errors 180 occur 1. Calibrate ALL Failed; execution stopped, 2. Calibration failed; Level Preset and 3. Calibration failed; Vector Modulation.

During the internal calibration:
Error: reference voltage oot (6.9...12.0V) occurs for Vector MOD calibration.
Error: No IQCON no convergence occurs for LEV PRESET calibration.

I run the learn table in LEVEL>ALC, error: CW: ALC_ON Voltage oot occurs.

I am not sure if it is the problem from IQ modulator or IQ Converter.

Every advice is welcome
