Table 9. USRP-2943 Module Front Panel Connectors (Continued)
Connector
Use
RF 1 TX1 RX1 Input and output terminal for the RF signal. TX1 RX1 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.
Note
The LED indications described in the following table occur only when you
use the NI-USRP API with the default API image. When you use LabVIEW FPGA,
you customize the LED indications.
