7.3 Device States
While operating, the R&S QAR runs through different states as shown in Figure 7-2 .
1. The device starts in
State.Initializing
.
2. The initialization runs:
● If initialization succeeds, the next state is
State.Ready_ToMeasure
.
You can now trigger a measurement.
● If errors occur during initialization, the next state is
State.Malfunction
.
It indicates that the device needs repair or replacement.
3. After data acquisition, the data analysis starts and the device switches to
State.Processing
.
While R&S QAR has this state, you can move the DUT.
4. The next state is:
●
State.Results_Ready
- the PLC can now read the results.
●
State.Malfunction
- if you trigger diagnostics but they fail.
5. When the PLC receives the results, it returns
Results_Received
.
The R&S QAR clears and deletes the current measurement results and goes back
to
State.Ready_ToMeasure
.

fails
Trigger.MeasureRadome=true
Or
