between the horizontal-axis time setting, internal sampling rate setting and tested signal frequency
is as follows.
Time setting (ms/div) Actual sampling rate
(kHz)
Frequency band (Hz)
0.2 250 10kHz-20kHz
0.5 100 5kHz-10kHz
1 50 2.5kHz-5kHz
2 25 1kHz-2.5kHz
5 10 500-1kHz
10 5 250-500
20 2.5 100-250
50-1000 1 100-10
