Hi all, I'm trying to run benchmark_tx.py on an E100 (rev.3). When I do, I get a bunch of "S" symbols printed to the screen and nothing shows up on the Spec Analyzer except a CW that appears for an instant and then dies. The reported sample rate is 800ksps. I'm not sure what's going on. Here's the command I used:
./benchmark_tx.py -f 910000000 --tx-amplitude=0.3 --non-differential -v --tx-gain=0.0 --args="type=E100" -m bpsk -r 400000 The output of uhd_usrp_probe is attached. This is the e1xx-003 release. uname -a gives: Linux usrp-e1xx 3.0.0 #1 Mon Mar 26 04:45:32 PDT 2012 armv7l GNU/Linux Thanks for your help! Respectfully, Sean Nowlan
