P2105A The Versatile Multi-Function Probe

The Picotest P2105A probe is a 50Ohm 1-port transmission line ‘Browser’ probe. With superior user ergonomics, the probe is simple to hold and probe with using integrated spring pins (pogo pins).

However, what sets the P2105A apart from other probes is its unmatched versatility. Users can swap (snap on and off) various heads on the common handle making this probe extremely versatile. It can be used for TDR, voltage ripple (as with other power rail probes), transient load current stepping, and near-field testing applications. In other words, it supports a variety of measurements including impedance. TDT/TDR, ripple, noise, PCB power rail, VRM (Voltage Regulator Module) and PDN impedance, and clock jitter. It has significant advantages in comparison to active probes and other types of passive probes as can be seen by a review of the specifications.

The P2105A is referred to as a ‘browser’ probe for its ability to quickly and easily be moved from point-to-point/rail-to-rail simply by reseating the probe points.

The probe achieves a very low inductance at the tip to mitigate space constraints on a dense PCB, while eliminating the need to add additional SMA connections or other test points necessary for impedance measurements. It is especially useful when there are multiple rails to assess and there is no time or PCB iterations available to provide test point implementations for each. Repeated measurements are simplified because connection is by simply touching the tip to existing trace.

The P2105A 5-in-1 probe uses interchangeable heads to change functionality. Probe heads are available for TDR/Ripple/Impedance, transient load current stepping, and near-field measurements. Different probe pitches are also color-coded.
