Hi everyone,
I am still a student and recently I am working with usrp. I have an
USRP1 with Basic TX and I am using uhd driver version 003_004_001. There
are some simple examples embedded with uhd driver.
I tried on tx_waveforms with following command:
tx_waveforms --rate 3200000 --freq 222064000 --spb 10000
I connected usrp1 to Spectrum Analyzer, but I couldn’t see any signals
on Spectrum Analyzer, even the garbage signal.
I tried tx_samples_from_file with following command:
tx_samples_from_file --freq 222064000 --rate 3200000 --file
~/Desktop/mod3.2-128.dat
mod3.2-128.dat is the file I got from CRC-DabMux and CRC-DabMod . This
file works absolutely fine with gnuradio-3.3.0, and I got DAB signal
from this file. But with the same problem, I couldn’t see any signals on
Spectrum Analyzer if using examples of uhd.
Do I have to set any extra parameters for USRP1 to make it work or these
examples do not support for USRP1, just support for USRP2, because I
have one USRP N210, and these examples work finely with N210?
Thank you very much.
