PCI RadioProcessor-G Board Connector Information
There are two main connector types on the RadioProcessor-G board: the BNC connectors and the SMA connectors –
see Figure 5 below. BNC connectors are mounted on the PCI bracket and are available outside of the computer. The
SMA connectors are mounted on-board and are available inside the computer only.
BNC Connectors
The four BNC connectors provide the primary interface with the RadioProcessor-G PCI board. All headers are
impedance matched to 50
Ω
. BNC4 is the Analog Input, used for data acquisition. BNC3 is the Analog Output port.
BNC2 and BNC1 are both general purpose digital outputs which can be controlled through the pulse program.
The analog output connector (BNC3), is not equipped with an interpolating filter. This allows for maximum flexibility
in output frequency, but it means that the output may appear somewhat quantized if no filter is used at the output. To
eliminate this behavior and obtain a smooth RF pulse, the user should filter the output with a band-pass or low-pass filter
which will cut off the undesired frequency components above the intended RF signal.
When using coaxial transmission lines, please terminate the lines with a 50 ohm impedance. See Figures 6
and 7 below.
