SCPI for the Radio Frequency Generator


The eLABin1 Radio Frequency Generator (RFG) can be remotely controlled by SCPI commands. Below are the SCPI commands for each of the subsystems of the RFG listed in tables.

Communication with the Radio Frequency Generator

Table 1. Communication with the RFG
Command	Description
`RFG`	Switches to the RFG from the main screen or from another instrument

Common commands

The following Common Commands apply to the entire configuration of the Radio Frequency Generator only when the Radio Frequency Generator is the instrument in foreground. As Common Commands are based in the current context, they apply to the current instrument, when the current view is the main screen. Commands apply for the entire configuration of the eLABin1.
