PK->MKR
This is a peak search function. Using marker 1, the GSP-810 begins at the current
marker 1 frequency and scans for a peak. When a peak is found in the trace, the
marker frequency is updated to show the frequency of the signal and the level of
the peak is also displayed. If no peak is found (that is greater in frequency than the
current marker position), the marker stops at the end of the trace. Another press of
the PK->MKR key will start a new search from the frequency point at the left-most
edge of the span. If the marker is not active, it will be activated and a new search
will begin from the frequency point at the left-most edge of the span. If the marker
is active but the bottom half of the LCD display does not show the marker, the peak
function will still complete and the marker on the CRT can be viewed.
