Turns off the analog output.
Log Video (RF Envelope, Ref=Mixer Level)
Selects the analog output to be the log of the video signal. In this mode, the pre-detector data is output to
the Analog Out connector with a Log scaling. The output is referenced to the current level at the mixer,
does not depend on display settings like Reference Level or dB per division, and it is not influenced by
the selected detector or any digital flatness corrections or trace post-processing (like Trace Averaging),
but does change with input attenuation.
The output is designed so that full scale (1 V) corresponds to –10 dBm at the mixer. The full range (0–1
V) covers 192.66 dB ; thus, 0 V corresponds to –202.66 dBm at the mixer.

Dependencies: Because the Log Video output uses one of the two IF processing channels,
only one detector is available while Screen Video is selected. All active traces
will change to use the same detector as the selected trace when Log Video is
activated.
Log Video output is not available while any EMI Detector is selected (Quasi
Peak, RMS Average or EMI Average), because these detectors use both IF
processing channels. Consequently, if the user chooses an EMI Detector,
there will be no Log Video output.
The output holds at its last value during an alignment, during a marker count,
and during retrace (after a sweep and before the next sweep starts).
This function depends on optional capability. The key will be blanked and the
command will generate an “Option not available” error unless you have
Option YAV licensed in your instrument.
Couplings: Log Video output changes while in FFT Sweeps, so for measurements that use
exclusively FFT Sweeps, or if the user manually chooses FFT Sweeps, the
Log Video output will look different than it does in swept mode.
