Differential Probes
Differential Probes determine the voltage drop between two points
in a circuit under test. Differential probes enable you to simultane-
ously measure two points and to display the difference of the two
voltages on your 2212.
Differential signal processing takes place in the probe itself, result-
ing in high common-mode signal rejection at higher frequencies.
Differential probe-tip signal processing minimzes the measurement
errors caused by differences in probes, cable lengths, and input
attenuators.
The common mode rejection ratio is a measure of how effectively
the probe cancels signals which are common to both inputs while
the common mode range indicates the maximum amplitude the
common signal can reach before the probe circuitry is saturated.
The 2212 works with the P6046 Differential Probe. This is a
100 MHz differential amplifier in probe form which connects one
oscilloscope input channel.
