MATH FFT Display the channel for the cursor measure.
Delta

Cursor 1
Read the position of Cursor 1 (the Freq is read
with reference to the start point of freq spectrum
and the Vamp is to the cursor F).
Cursor 2
Read the position of Cursor 2 (the Freq is read
with reference to the start point of freq spectrum
and the Vamp is to the cursor F).
When carrying out the cursor measurement, the position of Cursor 1 can be
adjusted with the CURSOR1 (VERTICAL POSITION) knob of Channel 1, and that
of Cursor 2 can be adjusted with the CURSOR2 (VERTICAL POSITION) knob of
Channel 2.

measured waveform, with the absolute value of the Vamp amplitude
difference between Cursor 1 and Cursor 2 displayed in the increment
window. The current position of Cursor1 is displayed in the Cursor1
window and that of Cursor2 is displayed in the Cursor2 window (see
Fig. 69
).
