10.4 Record Length and Sampling Rate
The record length is the data volume for each captured waveform. For example, if the record length is 700K, it
means that 700K sample points are captured by one trigger.
In the main menu, tap
to enter the record length setting menu, which can be set by tapping the
corresponding record length.

In normal refresh mode, if it is a single channel, the record length can be set to 14k, 140k, 1.4M, 14M, 28M,
Auto; if it is dual channel, the record length can be set to 7k, 70k, 0.7M, 7M, 14M, Auto; if it is three or four
channels, the record length can be set to 3.5k, 35k, 0.35M, 3.5M, 7M, Auto.
Record length and sampling rate
The record length is data volume collected per waveform capture. For example, if the record length is 0.7M, it
means that 700K sample points are captured by one trigger.
The oscilloscope record length and sampling rate have the following relationship:
