I have a 3406b and I am trying to use the sample VI coming with software. I notice two strange thing
- When I use PicoScope3000aExampleStreaming.vi , It does not let the sampling interval go less than 20nS any value smaller than 20 make the VI fives an error.
- When I use the PicoScope3000aExampleRapidBlockBulk.vi , It does let the time base goes less than 2 and even setting it to 2 it gives me a 3.5nS sample interval! I attached the screenshot of the vi with a 40 mhz/25nS as input. As you can see also the sampling rate in maximum case is an odd number of 3.56nS !!!
Can somebody please help me to understand :
1- why sampling rate is to odd 3.56nS and how I can set it to a integer ?
2- The 3000 series supposed to have 1nS sampling rate , how can I set to 1nS ?
Thakn you in advance
