    Table 1. Connector Descriptions
    Connector Access Function
    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
