Re: Re: USRP / DBSRX calibration

Staffan,

I am not sure how to post to the list, but…
I came up with a noise temperature of 2291. 5 degrees K.
This would not make for a good front-end type receiver,
but could work as a back-end.

Hi.

I’m trying to estimate the noise temperature in the DBSRX and USRP as a
part of a student project where we compare the USRP as an alternative
for the receiver in a radio telescope. I tried to convert the -165dBm/Hz
to Kelven but I’m not getting a sane value. I may be way out here but
would be very pleased to find out what the noise temperature might be,
in Kelvin.

Thanks
Staffan J.
