Dual-Channel Digital Oscilloscopes 

 

Functional Description 

 

VERTICAL System (cont’d) 

Measuring an FFT 

Spectrum using 

cursors

 

 

 

You can take two measurements on FFT spectrums : magnitude (in dB) 
and frequency in Hz. 

 

 

 

Measuring an 

 FFT amplitude

 

 

 

Once viewed the spectrum : 

1.  Press the “CURSOR” button to enter “Cursor” menu. 

2.  Press “Cusor Mode” to select “Manual”. 

3.  Press “Type” to select “Voltage”. 

4.  Press “Source” to select “MATH”. 

5.  Press “CurA”, turn the “Universal” knob to move Cursor A to the 

highest point of the FFT waveform. 

6.  Press “CurB”, turn the “Universal” knob to move Cursor B to the 

lowest point of the FFT waveform. 

7.  The amplitude (

∆

T) is displayed at the top right of the screen.
