The position of the marker becomes the reference point. The reference point level
is indicated by a horizontal line, the reference point frequency with a vertical line.
At the same time, the delta marker 2 is switched on.

6. Make the step size for the center frequency correspond to the signal frequency: in
the "Frequency" configuration dialog box, select "Center Frequency Stepsize" =
"Marker" .
The step size for the center frequency is now equal to the marker frequency.
7. Move the center frequency to the 2
nd
harmonic of the signal by pressing the UP ( )
key.
The center frequency is set to the 2
nd
harmonic.
8. Place the delta marker on the 2
nd
harmonic: in the "Marker To" menu, select the
"Peak" softkey.
The delta marker moves to the maximum of the 2
nd
harmonic. The displayed level
result is relative to the reference point level (= fundamental wave level).
The other harmonics are measured by repeating steps
and
, with the cen-
ter frequency being incremented or decremented in steps of 128 MHz using the UP or
DOWN keys.
7.10 Trace Configuration
A trace is a collection of measured data points. The trace settings determine how the
measured data is analyzed and displayed on the screen.
