More Information
When Continuous Peak Search is ON, a peak search is immediately performed and
then is repeated after each sweep. If Continuous Peak Search is turned on with the
selected marker OFF, the selected marker is set to POSition mode at the center of
the screen, and then a peak search is immediately performed and subsequently
repeated after each sweep.
When in Continuous Peak Search, *OPC does not return true, nor do :READ or
:MEASure return any data, until the sweep is complete and the marker has been re-
peaked. Note further that if the instrument is in a measurement such as averaging,
and Continuous Peak Search is ON, the entire measurement is allowed to complete
(that is, all the averages taken up to the average number) before the re-peak takes
place, and only then will *OPC go true and :READ or :MEASure return data.
When Continuous Peak Search is turned ON for a marker, a little “hat” is placed
above the marker.
