Picotest P2105A Multi-Function TDR Probe - 15GHz Browser Probe

Product Code: P2105A

High-Performance TDR Measurement Solution The Picotest P2105A is a versatile 50-ohm, 1-port transmission line 'browser' probe engineered for precision time domain reflectometry (TDR) measurements. This multi-function probe features interchangeable snap-on heads that enable engineers to tackle five critical measurement types: TDR impedance testing, power rail ripple analysis, transient load stepping, near-field measurements, and PDN impedance characterisation.

Custom pitches available on request. S10 Load Stepper Head: Provides 0-10A transient load stepping with ~3ns rise/fall time for power supply validation testing. Near-Field Head: Available in 31 mil and 100 mil H-field loop configurations with 1GHz bandwidth for EMI troubleshooting. Browser Probe Design The P2105A's 'browser' designation refers to its ability to quickly move from point-to-point across PCBs without requiring permanent test points or SMA connections. The spring-loaded probe tips ensure reliable contact while the slim, ergonomic design provides excellent visibility and access to dense circuit layouts. TDR probe contact demonstration on PCB trace Compatibility and Integration Fully compatible with all 50-ohm test instruments including: Safety Note: Maximum voltage ratings: <50VAC and 75VDC. Always verify DUT voltage levels before connecting the probe.
