R&S FSW-K7
Parameters:
<CouplingType>
Example:
Manual operation:
INPut:DPATh <State>
Enables or disables the use of the direct path for frequencies close to 0 Hz.
Parameters:
<State>
Example:
Manual operation:
INPut:FILTer:HPASs[:STATe] <State>
Activates an additional internal high-pass filter for RF input signals from 1 GHz to
3 GHz. This filter is used to remove the harmonics of the R&S FSW in order to mea-
sure the harmonics for a DUT, for example.
This function requires an additional high-pass filter hardware option.
(Note: for RF input signals outside the specified range, the high-pass filter has no
effect. For signals with a frequency of approximately 4 GHz upwards, the harmonics
are suppressed sufficiently by the YIG-preselector, if available.)
Parameters:
<State>
Example:
Manual operation:
INPut:FILTer:YIG[:STATe] <State>
This command turns the YIG-preselector on and off.
