1-Port 50 Ohm Browser Probe

The P2105A is one of the lowest noise probes on the market, much lower than most active power rail probes. This makes it the perfect probe for TDR, voltage ripple, and impedance testing. It can measure TDR quantities when coupled with a TDR, voltage ripple in the time domain, and impedance in the frequency domain.

Key Features

  • 15GHz Single-Ended Precise High Bandwidth Probe for all Time Domain Reflectometry (TDR) Applications
  • 1x Attenuation
  • Compatible with the Picotest J2154A PerfectPulse TDR
  • Fixed pitches available: 20, 31, 40, 50, 60, 70, 80, 100, 150 mils, or GSG SMA
  • Compatible with all 50Ohm Instruments
  • Spring pins for easy landing
  • Short pins and integrated, but removable, PDN cable for low coupling and optimum shielding
  • Handheld browser style for repeatable and easy probing; Handle design fits most probe holders
  • Slim low-profile housing for comfort and visibility
  • Compatible with the Picotest Probe Holder

Applications *

  • Power rail measurements of voltage ripple
  • 1-port reflection impedance measurements (> 100mohm)
  • Low-cost PCB coupon tester-Characteristic Impedance PCB traces
  • Measure PCB trace length, characteristic impedance, and dielectric constant
  • Locate and detect impedance mismatches
  • Measure parasitic values of inductance and capacitance such as bond wires, vias, and ESL
  • Measure PCB trace path rise/fall time and overshoot/undershoot
  • Supports cable and trace loss modeling

* When coupled with the J2154A TDR

Custom pitches are available. The probe is compatible with all 50Ohm 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. When used with a TDR, getting it backwards won’t normally result in any damage. The P2104A and P2105A can do damage if connected backwards to an active power rail.
