Averaging of multiple acquisitions...
Averaging of multiple acquisitions...
Dear Pico Support & Engineering staff,
I want to average RF radar waveforms to improve SNR. Here are the specs:
5MHz center freq, 10MHz bandwidth,
PRF (pulse repetition frequency) of 10kHz
Record length is 40 microsec per waveform, so at 100Ms/sec, that is 4000 samples.
I am considering the 3206 but I wish to acquire multiple (up to 500) waveforms one after the other. Can I transfer all the samples to my PC in the deadtime between triggers (40us record length, 100us between successive triggers, so 60us inbetween to transfer the 4000 samples).
On the PC, I need to simply store and average 500 acquisitions and then save them to disk.
Is this possible? (I am currently using a regular scope, but as our radar work is outside the lab - I'm a geologist - the scope is heavy and consumes power).
Also, we generate a separate 10MHz signal and input it into the REFERENCE input of our scope so that the sampling clock in the scope and our clock are the same - this is a standard feature in most scopes - do you have an input for that?
Sincerely,
SA

Hi
Thank you for your post.
The data transfer time depends on a number of different things. If you are not using a full buffer then it will be quicker. Using USB2 and a full buffer I believe the transfer usually takes milliseconds rather than microseconds. It would not be possible to improve upon the time enough that it could be done in microseconds.
Best Regards
