Term interpretation
Nyquist frequency:
The highest frequency that any Real Time Digital Oscilloscope can measure is exactly half of the sampling rate under the
condition of no mistakes, which is called Nyquist frequency. If under-sampling occurs when the frequency sampled is
higher than Nyquist frequency, "False Wave" phenomenon will appear. So pay more attention to the relation between the
frequency being sampled and measured.
NOTE:
While FFT mode is turned on, DO NOT USE THESE SETTINGS:
1.) Horizontal window setting.
2.) Trigger control "SET 50%"
3.) Auto-scale function
4.) Wave record;
5.) MEAS SET1 and MEAS SET2.
