The following discussion covers block-level theory for the 1141A/1142A differential
probe system. Refer to the block diagram below.
The differential probe system consists of two units, the 1141A Differential Probe with
its accessories and the 1142A Probe Control and Power Module. For purposes of the
following discussion, these will be called the probe and the control module respectively.
