In I/Q Analyzer (IQA) mode there are two main types of measurements: Spectrum and Waveform.
Here is the recommended procedure when querying trace-data or using marker-data using SCPI commands:
1. Set the Measurement to the desired type, if not already set:
- For Spectrum data, use the :CONFigure:SPECtrum command to set the measurement to Spectrum.
- For Waveform data, use the :CONFigure:WAVeform command to set the measurement to Waveform.
2. Change to Single acquisition mode by using INITiate:CONTinuous OFF, if the unit is not already in Single acquisition mode.
3. Execute one acquisition by using INITiate:IMMediate.
4. Perform the data-query (trace and/or marker) using the corresponding SCPI command.
