Then trigger system setting finished (ref to fig. 16).
Threshold voltage system
Threshold voltage system is to set high/low of the trigger voltage. The system already
fixed the setting for normal logic voltage as CMOS, LVMOS etc. And you can set any
trigger voltage using custom setting.
The signal voltage is 3.3V and we set threshold voltage as "LVCMO3.3/1.7V" as
below steps:
1. Press "1 (Threshold)" key and the menu appears.
2. Press "F1" key till Channel display as "CH00~CH03"
3. Press "F2" key till threshold display as "LVCMOS3.3/1.7V".
Then the threshold setting is finished (ref to fig. 17).
Sampling system
The waveform accuracy reverts from sample data depend on sample rate for
measured signals. The waveform reverted in LA is referring to the sample signals storage
