MARKER
The upper carrier sideband is tracked with m then
zoomed in with [T] Q m (%1.
As the carrier frequency is changed, the sideband response will tend to remain in the center of the display. The
center frequency and marker frequency reads out the sideband's frequency.
A combination of (::GKw:l and a allows the "real time" signal frequency drift to be read on the display.
PRESELECTOR PEAK
Preselector peak automatically adjusts the preselector tracking to peak the signal at the active marker. When the
marker is tuned to a signal and m is pressed, an internal routine searches for the peak response of the
preselector and adjusts the tracking accordingly. Using preselector peak prior to measuring a signal yields the most
accurate amplitude reading.
Preselector peak operates with the I--] , (,,,. , or m markers. If the marker is OFF pressing m will initiate a
peak search routine and then peak the response at that marker. A "PEAKING!" message appears on the active
graticule area to indicate operation of the peaking routine. PRESELECTOR PEAK only operates in the 2 - 22
