|CH 0 IN||Input||CH 0 IN and CH 0 OUT each function as a fixed-gain amplifier. These channels offer a low noise figure and a flat frequency response. CH 0 IN and CH 0 OUT are AC-coupled.|
|CH 0 OUT||Output|
|CH 1 IN||Input||CH 1 IN and CH 1 OUT each function as a programmable amplifier with switchable main and direct paths. The main path offers fixed gain amplification preceded by a step attenuator that is adjustable in 1 dB nominal steps. The direct path bypasses the programmable circuitry and routes the signal directly to the output. The direct path passes DC level to output, whereas the main path is AC-coupled.|
|CH 1 OUT||Output|
Indicates the basic hardware status of the NI RF signal conditioning module.
OFF—The module is not yet functional, or has detected a problem with a PXI power rail.
AMBER—The module is being accessed.
GREEN—The module is ready to be programmed.
Indicates the operational status of the NI RF signal conditioning module.
OFF—The module is in an uninitialized state.
GREEN—The module is in a ready state or in use.
