The Input Mode input Mode
button on the probe toggles the
internal probe input selector
switches among the four input
mode selections. The mode can
also be selected from the drop-

signal from a single connection.
A-B mode The A-B Mode is used
for making differential signal
measurements and represents
the traditional differential probe
functionality. Since the A-B Mode
measures the difference between
the A and B input signals, it
eliminates any common mode
voltage, such as a DC bias
common to both inputs, within
the CMRR performance capability
of the probe.
