P2100 Probe Instructions 1
P2100 Passive Probe
The P2100 is a compact, 1.5 meter passive probe with selectable
1X/10X attenuation. The probe is designed for use with general
purpose oscilloscopes with input capacitance between 18 and 35 pF.
There are no user-serviceable parts in the P2100 probe.
Features and Accessories
Table 3 shows the features and accessories of the P2100 probe.
Table 3: Features and standard accessories
Feature/Accessory Description
10 X1X Probe attenuation. This switch selects the attenuation factor of
the probe.
Hook tip
Hook tip. Connects the probe tip to wires and component leads
for hands-free measurement.
NOTE. For a solid connection, firmly push and twist the hook tip
onto the probe tip before using.
Replacement part number: 013-0318-00
Color
marker
bands
Color marker bands. Attach matching pairs of the color marker
bands onto the strain-relief sections of cable at the probe head
and compensation box. When several probes are connected to an
instrument, the color marker bands enable quick verification of
which probe is connected to which instrument channel.
Replacement part number: 016-0633-00
Ground lead. Use the ground lead for connecting the probe
ground to the circuit.

Probe Compensation
Due to variations in oscilloscope input characteristics, probe
low-frequency compensation may need adjustment after moving the
probe from one oscilloscope to another. If a 1 kHz calibrated square
wave displayed at 1 ms/division shows significant differences
between the leading and trailing edges, perform the following steps
to optimize low-frequency compensation.
2. Connect the probe to the calibration signal on the oscilloscope
front panel.
3. Press AUTOSET or otherwise adjust your digitizing oscilloscope
to display a meaningful waveform.
4. Adjust the trimmer in the probe until you see a perfectly flat-top
square wave on the display. See Figure 4.
