Use Sequence Mode
Sequence is also an acquisition mode, which does not display a waveform during the
sampling process. This improves the waveform capture rate, to a maximal capture rate of
400,000 wfs/s. So it can capture the small probability events effectively. The oscilloscope
runs and fills a memory segment for each trigger event. The oscilloscope screen is not
updated whilst the oscilloscope is busy acquiring multiple segments. The oscilloscope
continues to trigger until memory is filled, and then displays the waveforms on the screen.
To use the sequence mode, the HORIZONTAL Format must be set to YT.
Do the following steps to use the sequence mode.
1. Press the Acquire button on the front panel to enter the ACQUIRE function menu.
2. Press the Sequence softkey to enter the SEQUENCE function menu.
3. Press the Segments Set softkey; and then turn the Universal Knob to select the
desired value.
Do the following steps to replay the sequence waveform under history mode:
1. Press the History softkey to enable HISTORY function.
2. Press the List softkey to turn on the list display. The list records the acquisition time of
every frame and shows the frame number that is displaying on the screen.
3. Press the Frame No. softkey; and then turn the Universal Knob to select the frame to
display.
