Digital Filter
Press the MATH button to enter the mathematical operation menu is. The POSITION and the SCALE knobs
can be used to change the vertical position and the vertical profile of the mathematical operations. Under
maths operation the horizontal position cannot be independently adjusted, it will change automatically
according to the analog input channel signals.

5.2 FFT
Using FFT (Fast Fourier Transform) mathematical operations, the time domain signal (YT) can be converted
into frequency domain signal. The following types of signals can be easily observed using FFT:
● Harmonic content and distortion in measurement system
● Performance of noise in DC power supply
● Vibration Analysis
