Digital scope usrp code

Hi !

I’m planing to use the usrp as a 4-channel 64 MHz transient recorder.
Has anybody done something like that so far ?
Also, I want to send a stimulus signal with the usrp (e.g. a chirp) and
then
record the response of my system. The RX channels have to be
synchronized to
the TX channels. Another feature I want to implement is hardware
averaging of
transients.
