Trigger
Hold

off
Trigger hold-off can observe the complex waveforms (such as pulse train). Hold-off time is the amount of time
the oscilloscope waits before re-enabling the trigger circuit. During the hold-off period, the oscilloscope will not
trigger until the hold-off time is over. For example, a set of pulse train, which is required to trigger on the first
pulse, the hold-off time can be set to the pulse train width.
Press the HORI MENU on the horizontal control area and then adjust the Multipurpose knob to set the trigger
hold-off time. Input a combined waveform to CH1, and adjust the trigger hold-off time until the waveform can be
triggered steadily, as shown below:
Chapter 4 Sampling System Settings
Sampling is taking analog input signal and converts it into discrete points by using the analog to digital converter (ADC).
Press the ACQUIRE key to enter the sample menu.
