R&S ESU Remote Control – Description of Commands
INSTrument Subsystem
INSTrument:COUPle NONE | RLEVel | CF_B | CF_A
In analyzer mode, this command selects the parameter coupling between the two measurement
windows screen A and B.
Parameter: NONE: No coupling. The two measurement windows are operated like two
independent "virtual" devices.
RLEVel: The reference levels of the two measurement windows are coupled.
CF_B: The center frequency of screen B is coupled to the frequency of marker 1 in
screen A.
CF_A: The center frequency of screen A is coupled to the frequency of marker 1 in
screen B.
