Strain Relieving The Probe Heads - Keysight InfiniiMax III N2800A Series User Manual

Strain Relieving the Probe Heads

High-performance probes have small physical geometries to ensure the lowest possible
loading and best electrical response. Because of their small size, probing accessories are
often delicate. It is important to mechanically secure your probes to protect both your
equipment and designs from damage. There are several methods that Keysight
recommends:
Tack-putty
Keysight recommends the use of tack-putty for securing both probe heads and amplifiers.
Wrap a small amount of tack-putty around your probe head cables, taking care to not
pinch them. The mass can then be secured to a rigid body neat your DUT.
A similar techniques can be used to secure probe amplifiers where you apply some
tack-putty to the underside of the probe amplifier body and attach it to a rigid body near
your DUT.

You can also use putty with a positioner, such as the Keysight N2787A. The same
positioner can also be used to support your probe amplifier as shown in
page 28.
