Hi,
Using *uhd_cal_tx_iq_balance* and *uhd_cal_rx_iq_balance*, I am able to
find the coefficients of IQ Imbalance. However, I am having difficulty in
interpreting these results.
1) In calibration file, at lo_frequency=915MHz, correction_real=-0.00548
and correction_imag=0.00960. How can I estimat
Hi,
I want to disable automatic calibration of DC offset and IQ imbalance in
USRP Source block.
I am aware that I need to pass bool value 'false' as the argument to
*set_auto_dc_offset* and *set_auto_iq_balance*. The USRP Source block
itself provide this facility in the tab *FE Corrections*. Howe

Hi,
I am trying to measure IQ Imbalance of USRP N210 with WBX daughterboard:
After running *uhd_cal_rx_iq_balance*, I got following error:
*Error: This dboard has no serial!*
