Need help with USRP simulation test


#1

Hi,

I am running siggen and oscope test with USRP1.

I am expecting a smooth sine waveform with this:
C[root@fodora usrp]# usrp_siggen.py --sine -f 1e6 -i256
Using TX d’board A:

But I am getting some error in oscope.py and the attached oscope output
does
not give me the expected waveform
[root@fodora ~]# usrp_oscope.py -g0 -d64

** (python:21011): WARNING **: IPP request failed with status 1030

** (python:21011): WARNING **: IPP request failed with status 1030
uO

Does anyone know what is wrong with my setup?

Thanks,
Pete

This funny message can be ignored. It’s wxPython related.

You have no transmit daughterboard installed on side A.
You’re sending a zero Hz sine wave.

$ usrp_siggen.py --help
Usage: usrp_siggen.py [options]

Options:
-h, --help show this help message and exit
-T TX_SUBDEV_SPEC, --tx-subdev-spec=TX_SUBDEV_SPEC
select USRP Tx side A or B
-f RF_FREQ, --rf-freq=RF_FREQ
set RF center frequency to FREQ
-i INTERP, --interp=INTERP
set fgpa interpolation rate to INTERP
[default=64]
–sine generate a complex sinusoid [default]
–const generate a constant output
–gaussian generate Gaussian random output
–uniform generate Uniform random output
-w WAVEFORM_FREQ, --waveform-freq=WAVEFORM_FREQ
set waveform frequency to FREQ [default=0]
-a AMPL, --amplitude=AMPL
set waveform amplitude to AMPLITUDE
[default=16000.0]
-g GAIN, --gain=GAIN set output gain to GAIN [default=none]
-o OFFSET, --offset=OFFSET
set waveform offset to OFFSET [default=0]

This will get you a sine wave out at 10.0 MHz:

$ usrp_siggen.py --const -f 10M -i 128

This will get you a sine wave out at 10.1 MHz:

$ usrp_siggen.py --sine -w 100k -f 10M -i 128

This will get you a sine wave out at 9.9 MHz:

$ usrp_siggen.py --sine -w -100k -f 10M -i 128
