Hi
I would be grateful if anyone could explain more about the TX/RX calibration
utilities provided by UHD:
uhd_cal_rx_iq_balance: uhd_cal_tx_dc_offset:
uhd_cal_tx_iq_balance:
a) I found them installed in one of the UHD directories. Not sure now, but
wanted to know if the sa
HI
I am presently trying to work with USRP N210 with a SBX daughter board
connected to a Host laptop with Ubuntu 12.10 installed.This laptop had a
version of GRC and UHD installed when I got it.
But even though I was able to run some uhd example programs like tx_waveform
and uhd_siggen_gui.py iw a
om 0.035 V untl 1.5
V? is that within the usrpN210's working levels?
Thanks

Hi,
I am trying to characterize the TX and RX characteristics of USRPN210 with a
SBX board.
I have tried one test : Amplitude Variation effects, by varying the
amplitude in steps and finding out the o/p power through spectrum analyser.
The foll are the readings I got.
Amplitude level 921.25 MHz
