NI Scope configure vertical timing

[LilySamchuk]

Hello. I hope this is a right place to ask my question. 

I quite new to LabView and now trying to understand the NI-Scope initialization procedure. In vertical timing VI, there is min record length. if my minimum sampling rate is 2 MHz and min record length 14000000, does it mean that 14000000 samples will be recorded per second? And the sampling period is 0.5 us?

Thank you

A sample rate of 2MS/s means a sample period of 0.5µs. And it means 2 million samples per second.

A record length of 14M samples means time = (number of samples) / samplerate = 14MS / 2MS/s = 7s…

I believe you mean Horizontal Timing and the Vertical axis is typically volts/div... 

If you consider a typical oscilloscope has 10 divisions on the Horizontal scale:

Record Length =  Time/div (seconds) * Sample Rate * 10 (divisions)

Hello. I am a bit confused with this block  niScope Configure Horizontal Timing specifically with min record length. Can someone explain how it is determined and how it workds? Thank you
