Memory and Playback

If I were to use a throttle to reduce my data rate from 50M (record
to 25M, would the fact that I only have 4GB of RAM and a 5GB data file
alright? I seem to be having playback problems with the large data file
current amount of memory. The file played back fine when stored on a 5GB
RAMDisk (8GB total RAM), but I have had to go back to 4GB of memory. I
would like to work with the data while I wait for a memory upgrade.

Hi Paul,

Can you reduce the bandwidth of the recording you are taking? 50M is a
to record unless you carefully design and understand the limits of your
recording media, bus, etc. Even just streaming it and processing the
samples in realtime with no recording may be difficult, depending on

I would suggest that you reduce your bandwidth to 8 MHz or less and
there. Then, once you’ve solved any other problems, you can focus on
getting the full bandwidth if you really need it.

I routinely record long, 1 MHz spectrum files to disk without issue on
commercial OTS hardware.

I hope this helps.

Very Respectfully,

Dan CaJacob
