This page provides an index containing technical data for the USRP and various daughterboards
USRP 1
| Specifications | |
|---|---|
| Rev | 4.5 |
| Power | 6 V / _ mA |
| Size (mm) | 160 x 160 |
| Weight (g) | 130 |
| Power consumption | ||
|---|---|---|
| State | DBSRX+TVRX | DBSRX only |
| Switch ON | 770 mA | 600 mA |
| Start | 1.60 A | 1.37 A |
| Stop | 900 mA | 730 mA |
RFX1200
| Specifications | |
|---|---|
| Rev | 3.0 |
| Frequency | |
| Noise Figure | |
| Antenna | TX/RX and RX2 |
| GPIO | |
| Power | __ V / __ mA |
| Size (mm) | 142 x 69 |
| Weight (g) | 49 |
RFX2400
TVRX
| Specifications | |
|---|---|
| Rev | |
| Frequency | 50 - 870 MHz |
| Noise Figure | bad |
| Antenna | |
| GPIO | |
| Power | __ V / __ mA |
| Size (mm) | |
| Weight (g) | 78 |
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
| 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 |
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
