436 Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz
18 Peak Search
Continuous Pk
When a marker is placed on a signal and Continuous Pk is pressed, the marker will remain
on the signal even if the signal frequency changes, as long as the amplitude of the signal
does not change by more than 3 dB from one sweep to another.
If the signal is lost, an attempt will be made to find it again and maintain the marker on the
signal peak. If there are other signals on screen near the same amplitude, one of them may
be found instead. Signals near 0 Hz cannot be maintained effectively, because they cannot
be distinguished from the LO feedthrough, which is excluded by intent from the search
algorithm.
This function is intended to maintain the marker on signals with a frequency that is
changing, and an amplitude that is not changing.
