Probing Techniques to Maximize CMRR
The common-mode rejection of the probe is highest when the probe
is applied directly to the circuit, without using adapters. However,
some probing tasks are made easier using accessories included with
the probe. The accessories shown in Figures 3 and 4 achieve a high
CMRR by minimizing the distance between the probe head and the
signal source.
