The Picotest P2105A probe is a 50 ohm single-port line TDR probe designed specifically for TDT/TDR applications. Featuring a 1-port reflector method, the P2105A supports a wide variety of measurements including impedance, ripple, noise, PCB power rails, VRM, and clock vibration. With its low inductance, this probe minimizes space constraints on dense PCBs and eliminates the need for additional SMA connections or other test points.

The P2105A is known as the 'browser' probe because of its ability to move easily and quickly from one point to another simply by resetting the probe points. This simplifies repeatable measurements, especially when there are multiple rails to evaluate and insufficient time or PCB iterations to provide a checkpoint implementation for each rail.

The P2105A comes in a variety of fixed pin steps (20, 31, 40, 50, 60, 70 or 100 mil spacing with 1X attenuation; GSG SMA and custom pitch are also available), making it compatible with all all 50 ohm devices, including the J2154A PerfectPulse TDR, vector network analyzer (VNA), oscilloscope and spectrum analyzer. The P2105A probe is also designed to work with a traditional single-ended TDR setup.
