Description
JTAG
A USB port that connects the host computer to the device FPGA for development
and debugging. LabVIEW FPGA does not currently support configuring or
programming the device FPGA using the JTAG connector.
RF 0 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.
AUX I/O
General-purpose I/O (GPIO) port. AUX I/O is controlled by the FPGA.
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.
