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
This terminal is not used for this device.
PPS IN
Input terminal for the PPS timing reference. PPS IN is an SMA (f)
connector with an impedance of 50 Ω and is a single-ended input
channel. 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.
