The Picotest P2105A probe is 50 ohm 1-port transmission line ‘Browser’ probe for TDR applications. This precision probe supports a variety of measurements using the 1-port reflection methodology including primarily impedance and TDT/TDR, but also ripple, noise, PCB power rail, VRM (Voltage Regulator Module), and clock jitter. It has significant advantages in comparison to active probes and other types of passive probes.
The P2105A is a referred to as a ‘browser’ probe for its ability to easily and quickly 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 not 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 comes in various fixed pin pitches (20, 31, 40, 50, 60, 70, or 100 mil spacing with 1X attenuation; GSG SMA and custom pitches are also available).
The probe is compatible with all 50 ohm instruments, including the J2154A PerfectPulse TDR, vector network analyzers (VNAs), oscilloscopes, and spectrum analyzers. The probe is designed to work with the traditional single ended TDR setup.

All About Probes and Ensuring Accurate Measurements
Power Integrity Expert and Founder of Picotest, Steve Sandler discusses the topic of probes. He explains how they work, why there are so many varieties of them, and how to ensure you get accurate measurements.
Video on Extended Range 2-Port Shunt Thru Measurement
In this video, Steve Sandler shows how to simplify one of the more complicated impedance measurements. The 2-Port shunt thru measurement is powerful and accurate down to very small impedance. Using the Bode 100 you can measure power distribution network impedance and decoupling capacitors with a very wide dynamic range.
Step Load Testing with Picotest P2102A 2-Port Probe
This video demonstrates the new Picotest P2102A 2-port ‘Browser’ probe specially designed for measuring power integrity applications including voltage regulator module (VRM) impedance and stability, power distribution network (PDN) impedance, and power supply transient response.
Picotest P2102A 2-Port Calibration with CMT VNA
This video looks at how to perform a full calibration on the Copper Mountain Compact 2-port VNA using the Picotest P2102A 2-port probe and the P2100A-CAL calibration board that comes with the probe. The Copper Mountain VNA is the ideal benchtop 2-port wide bandwidth network analyzer for power integrity type measurements.
