Strain Relieving The Probe Heads - Keysight InfiniiMax III+ 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. Although tack putty
and low-temperature hot glue are recommended, you can also use other methods
such as tape or hook-and-loop strain relief. Keep in mind that different accessories
have different cable stiffness. You should choose a strain relief method appropriate
for the cable stiffness. For instance, it is best to secure the stiffer N5439A near the
SMP connectors and form the cable to the optimal location.
Do not kink cables. Do not crush cables. Do not use aggressive adhesives or high

temperatures.
Tack-putty
Keysight recommends the use of tack putty for securing both probe heads and
amplifiers. Tack putty can be ordered using part number N5439-65201. 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.
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 N2787A as shown in
