how to set sample clock timebase rate

Postby freemason » Tue Sep 01, 2015 7:06 pm

I am using Picoscope 4824, and have a requirement of setting a sample clock of 6.67MHz, how would i set up this?

i have the following setting on national instruments card and i want to replicate this on picoscope
Device: DAQ::1 (PCMCIA-5102)
Sample Rate (S/s): 6.667M
Record Length: 1.051k
Acquisition Mode: N Samples

The master clock of the 4824 is 80Mhz, and the possible sampling frequencies are related to this value, defined by the equation 80/(n+1) where n is the timebase. So for a timebase of 11 the sampling frequency will be 80/(11+1) or 6.6666666... MHz

So provided this is the frequency you actually require, and not specifcally 6.67MHz, then all you would need to do is select a timebase of 11 in the RunBlock function call.
