Error message: failed to set center frequency

GNU Radio
1

Hello,

I am using the USRP2 with the XCVR2450 db and experience the error
message
“failed to set rx center frequency” from time to time. Is this a known
problem
and if so, is there a way to solve it?

I tested with the program usrp2_rx_cfile.py and with different boards.

Regards,

Christoph

The XCVR has a low band range and a high band range

#define LB_FREQ_MIN U2_DOUBLE_TO_FXPT_FREQ(2.3e9)
#define LB_FREQ_MAX U2_DOUBLE_TO_FXPT_FREQ(2.6e9)

#define HB_FREQ_MIN U2_DOUBLE_TO_FXPT_FREQ(4.8e9)
#define HB_FREQ_MAX U2_DOUBLE_TO_FXPT_FREQ(6.1e9)

may I ask what frequency you requested?

Hi,

I requested 2.412GHz. This is within the range.

@ Andrea: I tried it with another board and it worked. But the curious
thing
is that it worked with this specific board a couple of times before and
I
didn’t change the configuration. Maybe it broke just during my task.

Thanks,

Christoph
