This page provides an index containing technical data for the USRP and various daughterboards

Note: Being a TV tuner, TVRX has 75 ω input. When using 50 ω cables and antenna, this will result in an SWR of ~ 1.5 (TBC), which is not that bad considering all other deficiencies of a TV tuner.
Using FFT spectrum analyser (avg. α = 0.07) we could detect a -120 dBm FM signal (3 kHz deviation) at 435 MHz, 250 kHz sampling bandwidth.
DBSRX

Rev | 2.2 |
Frequency | 800 - 2400 MHz |
Noise Figure | 3-5 dB |
Antenna | only one |

Weight (g) | 20 |
This receiver performs surprisingly well. Using the FFT spectrum analyser (avg. α = 0.07) we could detect a -132 dBm CW signal at 2.25 GHz, 250 kHz sampling bandwidth.
Channel Filter
The DBSRX has a programmable channel filter at the output that can be programmed within 1 and 60 MHz.
Python: u.subdev.set_bw(1e6) # set bandwidth to 1 MHz C++: TBD
LFRX
