5) Press CH1 button to display CH1 menu.
6) Turn the “S/div” knob to adjust sampling rate (at least double bigger than frequency of input signal).
7) If FFT display on full screen, press CH1 button again to remove channel waveform display.
8) Press the “CURSOR” button to enter “Cursor” menu.
9) Press the “Cursor Mode” button to select “Manual”.
10) Press the “Type” option button to select “Voltage”.
11) Press the “Source” option button to select “MATH”.
12) Press the “CurA” option button; turn the “Universal” knob to move Cursor A to the highest point of
the FFT waveform.
13) Press the “CurB” option button, turn the “Universal” knob to move Cursor B to the lowest point of the
FFT waveform.
14) The amplitude ( △T) displays on the top of the left screen.
2. Measure FFT Frequency
1) Press the CURSOR button.
2) Press the “Cursor Mode” button to select “Manual”.
3) Press the “Type” option button to select “Time”.
4) Press the “Source” option button to select “MATH”.
5) Press the “CurA” option button, turn the “Universal” button to move Cursor A to the highest position of
the FFT waveform.
6) The value of CurA displaying on the top of the left screen is FFT highs frequency. This frequency
should be the same as input signal frequency.
