Set to automatic trigger. The DSO will continuously perform data acquisition
without triggering signal.
Set to normal trigger. The DSO will only perform data acquisition when there is
triggering signal.
Set to single trigger. The DSO will only perform 1 cycle of the data acquisition
when there is triggering signal.
Block the DC component of triggering signal.
Pass through DC and AC components of triggering signal
Reject high-frequency component of the triggering signal (over 80kHz signals).
Reject low-frequency component of the triggering signal (below 80kHz
signals).
Reject high-frequency noise, reduce the probability of mis-triggering.
4.2 Pulse width trigger
For pulse width trigger, the trigger time shall be subject to pulse width of the triggering
signal. You can capture abnormal pulse by setting pulse width conditions.
Table 4-2 Pulse width trigger menu
Set CH1 as the triggering signal source
Set CH2 as the triggering signal source
Set external trigger input channel as the triggering signal source
Set AC power line as trigger source
Block the DC component of triggering signal.
Pass through DC and AC components of triggering signal
Reject high-frequency component of the triggering signal (over 80kHz
signals).
Reject low-frequency component of the triggering signal (below 80kHz
signals).
Reject high-frequency noise, reduce the probability of mis-triggering.
When there is no signal input, the system will automatically collect waveform
data and the scan base line will be displayed on the screen. When there is
signal input, the system will automatically switch to trigger scan.
Stop collecting data when there is no trigger signal, the system will conduct
trigger scan when the trigger signal generates.
The DSO will only perform 1 cycle of triggering when there is triggering signal.
