USRP-2922 Front Panel and LEDs
| Connector | Description |
|---|---|
|
RX 1 TX 1 |
Input and output terminal for the RF signal. RX 1TX 1 is an SMA (f) connector with an impedance of 50 Ω and is a single-ended input or output channel. |
| RX 2 | Input terminal for the RF signal. RX 2 is an SMA (f) connector with an impedance of 50 Ω and is a single-ended input channel. |
| REF IN | Input terminal for an external reference signal for the local oscillator (LO) on the device. REF IN is an SMA (f) connector with an impedance of 50 Ω and is a single-ended reference input. REF IN accepts a 10 MHz signal with a minimum input power of 0 dBm(.632 Vpk-pk) and a maximum input power of 15 dBm(3.56 Vpk-pk) for a square wave or sine wave. |
| PPS IN | Input terminal for the pulse per second (PPS) timing reference. PPS IN is an SMA (f) connector with an impedance of 50 Ω and is a single-ended input. PPS IN accepts 0 V to 3.3 V TTL and 0 V to 5 V TTL signals. |
| MIMO EXPANSION | The MIMO EXPANSION interface port connects two USRP devices using a compatible MIMO cable. |
| GB ETHERNET | The gigabit Ethernet port accepts an RJ-45 connector and gigabit Ethernet compatible cable (Category 5, Category 5e, or Category 6). |
| POWER | The power input accepts a 6 V, 3 A external DC power connector. |
