6.1.2 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/16 measures the voltage between

the input channel and LLGND. The single-ended input configuration requires only

one physical connection (wire) per channel and allows the PCM-DAS16x/16 to moni-

tor more channels than the (2-wire) differential configuration using the same connec-

tor and onboard multiplexor. However, since the PCM-DAS16x/16 is measuring the

input voltage relative to its own low level ground, single-ended inputs are more sus-

ceptible to both EMI (Electro Magnetic Interference) and any ground noise at the sig-

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