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).
DBSRX
| Specifications | |
|---|---|
| Rev | 2.2 |
| Frequency | 800 - 2400 MHz |
| Noise Figure | 3-5 dB |
| Antenna | only one |
| GPIO |
|
| Power | 6 V / __ mA |
| Size (mm) | |
| Weight (g) | 20 |
Channel Filter
The DBSRX has a programmable channel filter at the output that can be set within 1 and 33 MHz (upper limit TBC).
Python: u.subdev.set_bw(1e6) # set bandwidth to 1 MHz C++: TBD
