2.4.2 RMD Pin Descriptions

X4 IF Input Channel 1

X4 is the input connector for the IF Channel 1.

pin description type
X4 IF input channel 1; DC blocked ; 50Ohm SMA connector IN

X3, X2 External Filter Channel 1

X3 and X2 are connectors for an external filter. There is a 70MHz IF filter on-board. If you don't use this frequency, you can connect an external filter. But be careful, you have to change the signal way on the PCB. There are two capacitors, which have to solder in direction of the SMA connectors. The detector is designed broadband. You can use it from 50MHz to 2000MHz.

X3 External filter output; 50Ohm SMA female connector OUT
X2 External filter input; 50Ohm SMA female connector IN

X1 Test-port Channel 1

X1 is a test-port output for channel 1.

pin description type
X1 IF input channel 1; DC blocked; 50Ohm SMA female connector OUT

X5 DC-Output Channel 1

X5 is the output port for the rectified IF signal.

pin description type
X5 DC output; 0..5V; SMA female connector OUT

X10 IF Input Channel 2

X10 is the input connector for the IF Channel 2.

pin description type
X10 IF input channel 2; DC blocked ; 50Ohm SMA female connector OUT

X9, X8 External Filter Channel 2

X9 and X8 are connectors for an external filter. There is a 70MHz IF filter on-board. If you don't use this frequency, you can connect an external filter.
