Re: Waveform acquire rate

Thanks for this update. The acquisition speed is now nearly what you quoted for the c code. I am now acquiring data at around 5kHz. Roughly a factor of 20 increase.

Re: Waveform acquire rate

It has been a while since I was able to explore this issue and I have simply lived with the low rates. However, in the past day or to I looked more closely at the Labview example for the 2000 series. The rapid block example seems to be using the wrong function calls. In the 2000 series programmers g...

Re: Waveform acquire rate

Martyn, I am now back in the lab and can check on the specifications you requested. Here are all the details I can think of. I am inputing a 50 ns pulse train at a rate of 20 kHz generated by a function generator. I am triggering on channel A and acquiring channels A and B The timebase is 1 meaning ...

Re: Waveform acquire rate

Martyn, Thanks for your reply. Unfortunately, I will not be near the equipment for a couple of weeks as I have left on vacation.

Waveform acquire rate

I have just starting using Labview 2014 with my new picoscope 2408B. Using the rapidblock example things seem to be working. I am looking at pulses about 20 ns in duration using a 100 ns window for the moment. The waveforms are being acquired well. The example seems limited to acquiring about 350 wa...
