Data corrupt or stale
This occurs when a FETC? is attempted and either a reset has been received or the
power meter state has changed such that the current measurement is invalidated (for
example, a change of frequency setting or triggering conditions).
Data corrupt or stale;Please zero and calibrate Channel A
When CAL[1|2]:RCAL is set to ON and the sensor currently connected to Channel A has
not been zeroed and calibrated, then any command which would normally return a
measurement result (for example FETC?, READ?, or MEAS?) will generate this error
message.
Data corrupt or stale;Please zero and calibrate Channel B
When CAL[1|2]:RCAL is set to ON and the sensor currently connected to Channel B has
not been zeroed and calibrated, then any command which would normally return a
measurement result (for example FETC?, READ?, or MEAS?) will generate this error
message.
