Hello, I'm using a channel on an x310 to sample the analog receiver on a radar system and store the data continuously on a host PC running CentOS 7. The other channel on the x310 is used to collect timing signals (like a transmit trigger signal) via the GPIO header on a basic Rx daughterboard (with a modified FPGA load)
I'd like to delay a fixed amount of time (say 2 ms) from the trigger signal on the GPIO to process a subset (about 100 us) of the receive signal and calculate RMS power during that interval. I'd like to do this on the Host PC and stream out the result as a UDP message. My question is this: What is my best bet in manipulating the data stream from the USRP block so that I can calculate the RMS power in that window of time delayed from the trigger? Stream to vector? Signal probe vector (I've read these are slow)? ZeroMQ? Thanks, Mark
