Math Functions Control
The math functions control allows the selection of the math functions add,
subtract, multiply, and FFT (Fast Fourier Transform) for CH1 and CH2. The
mathematical result can be measured visually and also using the cursor controls.
To select a math function, press the Math button to display the Math menu. The
settings of this menu are shown in the Table 2-3. The amplitude of the math
waveform can be adjusted by pressing the 1/2 key, selecting the scaling control,
and turning the entry knob. The adjustment range is in a 1-2-5 sequence from
1 mV/div to 10 kV/div. The scale setting is displayed above the status bar. The
position of the math function can be similarly adjusted.
