Basic operation
Probe input
The probe is electrically protected against static voltage. However, if you apply voltages above its design limits you may damage
the probe tip ampli
fi er. The limits are shown in the 4.25 V and 42 V range graphs on the following pages. (See Figure 2 on
page 17.) (See Figure 3 on page 18.)
Common-Mode signal range
The common-mode signal range is the maximum voltage that you can apply to each input, with respect to earth ground, without
saturating the input circuitry of the probe. A common-mode voltage that exceeds the common-mode signal range may produce an
erroneous output waveform even when the differential-mode speci
fi cation is met.
To verify the common-mode signal is within speci fi cation, set the probe to the 42 V range, temporarily connect one of the probe
inputs to ground, and connect the other probe input to one output of the differential signal. Repeat the procedure to test the
other output of the differential signal.
Differential-Mode signal range
The differential-mode signal range is the maximum voltage difference between the (+) and (-) inputs that the probe can accept
without distorting the signal. The distortion from a voltage that is too large can result in an invalid measurement.
