Oscilliscope Seconds of Waveform Recording Capability Question
Silver_Is_Money:
The spec sheet for the Hantek TO1154D tablet oscilloscope states that it has 8mpts of storage capacity. How does this translate into seconds of waveform recording capability. Would this mean that it records for 8 seconds from recording start to terminus? And if not, how many actual seconds of waveform recording can it capture for review?

Please search for it on the Internet before you ask, Google "memory depth sample rate" usually throws up good results with examples.

The answer to your question is complex and depends on many settings.
Am I right that you are about to buy your first scope?

Thank you! Time Duration of Waveform Recording = Record Length/Sample Rate
So if a scope advertises a 250 Msa/S sampling rate and an 8M record length:
8/250 = 0.032 seconds (or 32 ms) worth of record length being recorded for review.
Would this be correct?

Yes.
But... on many 'scopes you can reduce the sample rate to get more time.
eg. If a 'scope lets you reduce the rate to 1Msa/sec then you can record for 8 seconds.
