Access Key Description
Sets the center frequency equal to the
MKR→
reciprocal of the delta value. For use in zero
span mode.
Sets the center frequency step size equal to
MKR→
the reciprocal of the delta value. For use in
zero span mode.
Turns the marker noise function on or off.
MKR
When it is on, it normalizes the equivalent
amplitude of the measured noise to a 1 Hz
bandwidth.
, Moves the active marker to the next-highest
FREQ COUNT
trace peak relative to the current marker
PEAK SEARCH
position.
Finds the next peak to the left of the
PEAK SEARCH
current marker position.
Finds the next peak to the right of the
PEAK SEARCH
current marker position.
Defines what constitutes a peak on a trace.
PEAK SEARCH
The selected value specifies the amount
that a trace must increase then decrease in
order to be a peak.
— Places a marker at the highest point on a
trace and accesses a menu of marker
functions.
Places a marker on the highest point on a
FREQ COUNT
trace and displays the marker frequency
and amplitude.
Sets the minimum amplitude level from
PEAK SEARCH
which a peak on a trace can be detected.
Switches the signal tracking function on
MKR
and off. When it is on, it keeps the active
marker on the peak of the signal where it
was initially placed and keeps the center
frequency at the marker value. A K appears
on the left side of the display to indicate this
function is active.
