Since the X300 creates 16-bit samples, converting the complex floatsamples into complex integer samples would reduce this to 4 bytesper sample. A 60 msps stream would then require only 240Mbyte/secdisk write speed. And if you can stand the loss in samplingresolution, going down to 8-bit samples by using complex short sampleswould further reduce this to 120MBytes/sec.@(^.^)@ EdOn 9/21/21 10:45 AM, Marcus D Leech wrote:Well if you’re recording complex float samples, that’s 8 bytes each. At
60msps that’s 480Mbyte/second. Not too many disk subsystems can keep up
at that rate.
You might try short recordings into a RAM disk filesystem.

I use a USRP x300, when i want to use uhd and file sink in gnuradio ,
for high sample rate like 60M or 80M gnuradio can not record
file.Gnuradio print some character on log: i want to record a sample
not any other thing.
Is there any way that i can record with high sample rate in gnuradio?
my system is powerful:
Core i7
RAM 16
