[Discuss-gnuradio] Acceptable sampling rate and LO frequency for USRP LFRX

[LD Zhang]

Hi,

 

I have been using GRC and N210 to test my data acquisition scheme. My previous scheme worked well with probably standard sampling rate (10Msps) and LO at DC.

 

When I switched to a non-standard sampling rate (1.2 Msps) and non-standard LO (1.105 MHz), all hell seems to break loose.

 

One message appears to be helpful, says: “Hardware does not support requested sampling rate, request 1.200.. Msps, actual 1.2048… Msps.

 

I suspect my requested LO of 1.105 MHz also may not be met, but there is no message saying that.

 

My question is: how do my find out the LFRX supported sampling rate and LO frequency?

 

Thanks,

 

LD
