4.1.1 Single-Ended Inputs

A single-ended input measures the voltage between the input signal and

ground. In this case, in single-ended mode the PCM-DAS16x/12 measures the

voltage between the input channel and LLGND. The single-ended input con-

figuration requires only one physical connection (wire) per channel and

allows the PCM-DAS16x/12 to monitor more channels than the (2-wire) dif-

ferential configuration using the same connector and onboard multiplexor.

However, since the PCM-DAS16x/12 is measuring the input voltage relative

to its own low level ground, single-ended inputs are more susceptible to both

EMI (Electro Magnetic Interference) and any ground noise at the signal

source. The following diagrams show the single-ended input configuration.
