Table 1-1: Signal acquisition system characteristics (cont.)
With the same signal applied to each channel, CMRR is the ratio of the acquired signal amplitude to the
amplitude of the MAT H difference waveform, either (Channel 1 - Channel 2), (Channel 2 - Channel 1),
(Channel 3 - Channel 4) or (Channel 4 - Channel 3)

Section 4.11.1 of IEEE std. 1057. It is the ratio of the level of a signal input into one channel to that of
the s ame signal present in another channel due to stray coupling.

Characteristic
Description
This is the range of real-time rates, expressed in samples/second, at which a digitizer samples signals a t
its inputs and stores the samples in memory to produce a record of time-sequential samples. (IEEE
1057, 2.2.1)
