3. Turn the FUNCTION knob and move the H-C1 cursor to the position were it is
desired to learn the frequency and dBm value.
4.
The frequency and dBm value of the specified portion are displayed in the menu.
(Refer to page 23.)
The below diagram is an example in which the value of the secondary harmonic component
(C) is measured from the from the FFT results of a 100kHz sine wave.
→
dBm at f function is selected.
→
With the FUNCTION knob, the H-C1
cursor is moved to the point to be
measured (point C).
→
Displays frequency at the cursor
position.
→
Displays dBm value at intersection
between cursor and FFT waveform
(point C).
