Notes about the Analog Outputs
Screen Video
This mode is similar to the Analog Output of the HP 8566 family and the Video Out
(opt 124) capability of the Keysight PSA analyzer (E444x), although there are
differences in the behavior.
Screen Video output changes while in FFT Sweeps, so for measurements that use
exclusively FFT Sweeps, or if the user manually chooses FFT Sweeps, the Screen
Video output will look different than it does in swept mode
Because the Screen 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 Screen Video is activated.
Screen 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
Screen Video output.
The output holds at its last value during an alignment and during a marker count.
After a sweep:
–
If a new sweep is to follow (as in Continuous sweep mode), the output holds at
its last value during the retrace before the next sweep starts. If the instrument is
in zero-span, there is no retrace, as the instrument remains tuned to the Center
Frequency and does not sweep. Therefore, in zero-span, the output simply
remains live between display updates
–
If no new sweep is to follow (as in Single sweep mode), the output remains live,
and continues to show the pre-detector data
This function depends on optional capability; the selection is not available, and the
command will generate an “Option not available” error unless you have Option YAV
or YAS licensed in your instrument.
The Screen Video function is intended to be very similar to the 8566 Video Output
and the PSA Option 124. However, unlike the PSA, it is not always on; it must be
switched on by the Screen Video key. Also, unlike the PSA, there are certain
dependencies (detailed above) – for example, the Quasi Peak Detector is
unavailable when Screen Video is on.
