There is an importance compromise between recorded signal resolution and its
continuance (relate to time). The sample memory depth of LA is fixed and once
adding sample rate then resolution will get better accordingly. But it will decrease
the continuance for acquire signal. In a word, sample rate are quicker then the
continuance for recorded signal will get smaller but with better resolution.
Sampling system can set difference sample rate and storage depth.
We use 10 times sampling rate to measure the signal clock frequency of 1M, and
storage depth set as "Normal". Sampling system setting steps as below:
Press "
E(ACQUIRE)
" and menu appears.
Press "
F1
" or turn "
CH1 Volts/div
" knob till sample rate setting display
as"
10M
".
Press "
F2
" till storage depth display as "
General
".
Sampling system setting finished (ref to the fig.).
Then press "
F
" and start to sampling data. Display show as figure 20 when
sampling finished.
