:READ Subsystem
This set of commands combines the ABORt, INITiate and FETCh commands. It aborts any current triggering sequence and sets the trigger state to idle. It then initiates a new active measurement (i.e. begins the collection of new data). When the measurement is complete, it returns the result. These commands will not switch to another measurement.
To get the current measurement data, use the FETCh command.

Title
Read Constellation
Description
Triggers a new Constellation measurement and returns the results: EVM (rms), EVM (pk), RCE (rms), RCE (pk), Carrier Frequency, Freq Error, Freq Error, and the Base Station ID. The Constellation measurement must be the active measurement (specified by :CONFigure:DEMod CONStln). The current measurement can be queried using the command :CONFigure?
Data is returned as 8 comma-delimited values: EVM (rms) in %, EVM (pk) in %, RCE (rms) in dB, RCE (pk) in dB, Carrier Frequency in MHz, Freq Error in MHz, Freq Error in ppm, and the Base Station ID.
