Viewing Time-Sharing Of A Frequency With An Oscilloscope - HP 8590 E-Series User Manual

Note
When Option 105 is enabled, it'interrupts the internal signal path of the
spectrum analyzer, so several spectrum analyzer functions may not be
available under all conditions. These conditions include: marker noise
(MK NOISE ON OFF ), sample detection while in the frequency span mode,
quasi-peak detection (Option 103), and AM/FM demodulation and TV sync
trigger (Option 102). The marker counter function (MK CDUNT ON OFF ) is not
directly affected by the operation of Option 105, but many signals that are
appropriate for time-gating (for example, pulsed RF signals) will not be counted
correctly by the marker counter function.
