I'm sorry for the typo, yes after the USRP source block there is a complex to
float followed by a rational resampler for each of the four channels so it
decimates and records to file at 500 kS/s
Thanks for catching that. -Tom

occasionally still see some overruns though it takes a lot
longer for them to show up than with 4 channels at 1MS/s and
they don't always show up eachtime i run the script. The 4
channels at 1MS/s and writing to file at 500 MS/s causes
overruns every time I run the script.
You presumably mean 500kSPS, rather than 500Msps here?
How are you decimating the incoming sample stream down to the
file-write rate?
