Connector | Use |
---|---|
RX1 TX1 |
Input and output terminal for the RF signal. RX1 TX1 is an SMA (f) connector with an impedance of 50 Ω and is a single-ended input or output channel. |
RX2 | Input terminal for the RF signal. RX2 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 NI 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. |
