Marker functions measure the frequency and amplitude of a signal.
You can place a diamond-shaped marker on the signal peak to find
the signal's frequency and amplitude.
To activate a marker, press the

that the marker is the active function. Turn the knob to place the
marker at the signal peak. You can also use the
which automatically places a marker at the highest point on the
trace.
Readouts of marker frequency and amplitude appear in the active
function block and in the upper right corner of the display. Look at
the marker readout to determine the amplitude of the signal.
If another function is activated, the marker frequency and
amplitude can still be identified by looking at the marker readout in
the upper right corner of the display.
