Operating Basics
The P6133 probe is a 150 MHz, 10X, 2 meter, passive voltage probe designed
specifically for use with Tektronix 2400 Series oscilloscopes having bandwidths
less than or equal to 150 MHz.
The P6133 standard probe comes with a 2 meter cable length (1.3 meter length is
also available) and the Tektronix Subminiature probe tip/hybrid assembly, which
is fully compatible with the Tektronix Subminiature family of accessories.
The P6133 Option 25 probe comes with the Compact Series probe tip/hybrid
assembly and is available in 1.3 meter length only. The Compact size probe
tip/hybrid assembly is slightly larger in diameter than the Subminiature, offering
greater durability and ruggedness in those environments and applications where
required. The Compact tip is not compatible with the Subminiature series and is
supplied with its own accessories.
Optional accessories are available for both tip sizes. You can also convert the
Subminiature and Compact probe tip/hybrid assemblies to the Tektronix
Miniature series probe tip by using the subminiature/compact-to-miniature probe
tip adapter (see the optional accessories sections for the individual probe types).
Probe Compensation
WARNING. To avoid electric shock when using the probe, do not touch the
metallic portions of the probe head while connected to a voltage source.
Due to variations in oscilloscope input characteristics, probe low-frequency
compensation should be checked and or adjusted if you move the probe from one
oscilloscope input to another. Connect the probe tip to a 1 kHz square wave
signal (such as the oscilloscope calibrator output) and use a nonconductive
low-reactance alightment tool to adjust the probe compensation capacitor.
See page 9 for complete low-frequency and high-frequency compensation
adjustment procedures.

Inductive Effects of Probe Grounding
Ground lead inductance can significantly reduce the performance of a probe. As
shown in Figure 1, the ground lead inserts inductance into the signal path
forming a series-resonant circuit with the probe input capacitance C
R
as damping. This forms a resonant circuit with f

A six-inch ground lead has approximately 150 nH of inductance, which produces

shown in Figure 2.

Low-Inductance Ground
Lead
The low-inductance ground lead provided with all Tektronix P6133 probes
allows for a substantial reduction in ground-lead inductance, approximately
32 nH instead of 150 nH.
To install the low-inductance ground lead, refer to Figure 3 and perform the
following steps:
1. Unscrew and remove the ribbed-tip shell and slide off the ground collar with
ground lead.
2. Slip on the low-inductance ground lead collar (1) and reinstall the ribbed
plastic tip cover.
3. Install the low-inductance lead (2) from the accessory pack.
