The disconnected connection to the output is additionally shown when the output is
deactivated.
Active analog modulation is also indicated in the block.
To query the impedance of the RF outputs, use the command
:OUTPut<hw>:
IMPedance?
on page 577.
RF On
Activates RF signal output.
This function corresponds to the RF ON /OFF key.

5.5.1.2 RF Signal Modes and Characteristics
The CW, Sweep and List modes are available for generating the RF signal.
●
CW
The RF signal is generated with the set frequency and level. This is the default
mode.
●
Sweep
The RF signal is generated as a sweep with the set parameters.
It is not possible to activate frequency, level and LF sweep simultaneously.
●
List Mode
The RF signal is generated on the basis of a list of predefined frequency and level
values. The duration of the individual steps can be predefined.
Instruments connected downstream can be taken into consideration when setting the
frequency and level by entering a frequency and/or level offset.
Automatic level control ("ALC") ensures maximum level accuracy, even with I/Q modu-
lation.
