It is typically used for complex waveforms. The correct rejection setting is usually slightly smaller than one
repetition of the waveform. Setting the hold-off time to this time can become the only trigger point for the repetitive
waveform.
Changing the time base setting will not affect the trigger hold-off time.
Using Zoom function, you can tap “Run/Stop” to stop, then horizontally move and zoom the data to find the
position where the waveform is repeated. Use the cursor to measure this time and then set the hold-off time.
Use “SEQ” button for single acquisition
Usually when performing a single acquisition, you must initiate some operations on the measured equipment, and
the oscilloscope is not desired to trigger automatically before these operations. The trigger condition indicator
is displayed in the upper left corner of the screen before starting operations in the circuit (this means the pre-trigger
buffer is filled).
