The query commands read out the parameter values from the Analyzer. After a query command has been sent, the response should return via remote control interface.
The query commands have a question mark ('?') at the end of the command. Many of the commands have two forms. The form with a question mark writes the parameter, the form without a question mark reads out the parameter. For example:
SENSe:FREQuency:STARt 1MHz
SENSe:FREQuency:STARt?
