sample interval

Post by mhalqa01 » April 4th, 2019, 12:39 pm

Hi every body,
I saved an waveform as a csv file from my scope(Tektronix DPO 3014). after I opened the file I see that the sample interval is only 20usec. why is this very low? I need it to be higher than this. can any one help with that
Thank you

The sample interval will be a function of two things: The horizontal scale setting (time/div), and the Record Length that you have configured. By default, the Record length is 10,000 samples. If you need a smaller sample interval at a given time/div setting, you would go into the Acquire menu and increase the record length. In the DPO3000 series, I believe the record length can be adjust up to a maximum of 10Msamples.
