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.
