P6136 Instruction Manual

Operating Basics
The P6136 probe is a 350 MHz, 10X, 1.3 meter, passive voltage probe designed
specifically for use with Tektronix 2400 Series oscilloscopes having bandwidths
greater than 150 MHz. The P6136 comes standard with the Tektronix subminia-
ture-size probe tip/hybrid assembly and is fully compatible with the Tektronix
Subminiature family of accessories. The Compact series probe tip/hybrid
assembly comes standard on the P6136 Option 25. The Compact probe
tip/hybrid assembly is slightly larger in diameter than the Subminiature series,
offering greater durability and ruggedness in those environments and applica-
tions where required. The compact tip is not compatible with the Subminiature
series except for the ground collar and the low-inductance (2.3 inch) ground lead.
The P6136 Option 25 is supplied with a complement of accessories; optional
accessories are available for both tip sizes.
You may convert both probe tip assemblies to Tektronix Miniature series probe
tips by using the subminiature/compact-to-miniature probe-tip adapter (See the
optional accessory lists for each probes in the Replaceable Parts section
beginning on page 14).
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.
Probe Compensation
Due to variations in oscilloscope input characteristics, probe low-frequency
compensation should be checked and adjusted after moving the probe from one
oscilloscope input to another. To adjust the probe low-frequency compensation,
apply a 1 kHz square wave (such as an oscilloscope calibrator output) to the
probe tip. Using a nonconductive low-reactance alightment tool, adjust the probe
compensation capacitor through the hole in the compensation box to obtain the
squarest waveform at the front corner edge. See page 9 for complete low- and
high-frequency compensation adjustment procedures.
