Testing Rx LO Frequency

[emonk]

Is there a way to query the 2940R to find out the actual frequency of an LO? 

I ask this because I'm currently using the Coerced LO Frequency output from the Configure Frequency VI in USRP 14.5 to do my input frequency calculations, and occaisionally, after changing frequencies, that output appears to be wrong.

Thanks.

Oops.  A correction:  I'm actually using USRP 15.0.

Sorry.

Hi Emonk,

You should be able to use this property, set it to read, and attach an indicator to it.
