State
If enabled, the defined notch filter is applied to the baseband signal.
Remote command:
[:SOURce<hw>]:BB:ARBitrary:NOTCh
on page 833
etc. for the corresponding option:
[:SOURce<hw>]:BB:EUTRa:NOTCh
on page 833
[:SOURce<hw>]:BB:OFDM:NOTCh
on page 833
Clock Frequency
Indicates the current clock frequency of the waveform signal.
The value resambles the value set with the parameter "ARB > General > Clock Fre-
quency".
Notch Bandwidth /% is related to this value.
Remote command:

Number of Notches
Sets the number of notches.
Notches are defined individually; in the notch defienition table, there is one line per
notch.
