Key Features
Overview
The Picotest P2105A represents a breakthrough in measurement probe versatility, combining five essential test functions in a single, compact instrument. This precision 50-ohm transmission line probe delivers superior performance across TDR impedance measurements, power rail ripple analysis, transient load stepping, near-field EMI detection, and PDN characterisation applications.
The probe's innovative interchangeable head design allows engineers to adapt quickly between measurement types without investing in multiple specialised instruments. Each head is optimised for specific applications while maintaining the probe's exceptional 15GHz bandwidth and minimal circuit loading characteristics.
Compatible with industry-standard oscilloscopes and network analysers, the P2105A integrates seamlessly with the Picotest J2154A PerfectPulse TDR for complete impedance measurement solutions. The probe's browser-style operation enables rapid point-to-point measurements across multiple PCB locations without recalibration.
Available in multiple pitch configurations and attenuation levels, the P2105A serves applications from prototype validation through high-volume production testing. Its robust construction and ergonomic design ensure reliable operation in demanding laboratory and field environments.

Frequently Asked Questions
Have a Question?
-
Is calibration required for TDR measurements with the P2105A?
While calibration is not strictly required, it significantly improves measurement accuracy. The probe works with standard TDR calibration procedures using open, short, and load standards at the probe tip.
-
What cable length is standard with the P2105A?
The P2105A comes with a 1-metre SMA-Mini SMP PDN cable for low coupling and optimal shielding. Longer cables are available but may affect high-frequency performance.
-
What safety precautions should I observe when using the P2105A?
Never exceed the maximum voltage ratings of 50VAC or 75VDC. Always verify circuit voltage levels before probe contact. The probe is not isolated and should only be used on circuits within its voltage specifications.
-
Can the P2105A be used for power rail ripple measurements?
Yes, the P2105A is one of the lowest-noise power rail probes available, making it excellent for ripple measurements on voltage rails. It offers superior performance compared to many active power rail probes.
-
What is the measurement accuracy of impedance readings?
Measurement accuracy depends on the instrument used and calibration setup. Typical 1-port impedance reflection limits range from ~100mΩ to ~100kΩ. The probe itself introduces minimal error when properly calibrated.
-
How do I change between different probe head types?
The P2105A features a snap-on head design that allows quick changes between TDR/impedance, S10 load stepper, and near-field heads without tools. Each head is colour-coded for easy identification.
-
What oscilloscopes are compatible with the P2105A?
Any oscilloscope or instrument with 50-ohm input impedance can use the P2105A. It works particularly well with high-speed oscilloscopes when paired with the Picotest J2154A TDR generator for complete impedance analysis.
-
Can the P2105A measure both single-ended and differential impedances?
The P2105A is designed for single-ended TDR measurements. For differential impedance testing, use two P2105A probes together or consider the dedicated Picotest P2103A differential TDR Probe.
-
What pitch sizes are available for the P2105A TDR probe?
The P2105A is available in fixed pitches of 20, 31, 40, 50, 60, 70, 80, 100, and 150 mil spacing, plus GSG SMA configuration. Custom pitch sizes can be manufactured to order for specific applications.
