20 GHz Single-Ended TDR Probe





Features & Benefits

  • 20 GHz Probe Tip Bandwidth
  • 50 Ω Impedance TDR Passive Probe
  • Undisturbed 50 Ω Probe Reference Section
  • Includes 20 GHz Precision SMA Cable
  • Probe Tip Pressure Actuation Feature used to actuate 80A02 EOS/ESD Protection Module


  • Circuit Board Controlled Impedance Testing (TDR)
  • Designed for use with 80A02 EOS/ESD Protection Module

The P8018 Handheld TDR Probe is a greater than 20 GHz, 50 Ω input impedance, single-ended passive probe with a precision 20 GHz bandwidth SMA cable that provides a high performance solution for electrical sampling TDR circuit board impedance characterization and high-speed electrical signal analysis applications. The P8018 probe can be used as a stand alone high bandwidth probe, but it is specially designed with features to be used with the 80A02 EOS/ESD Protection Module for protecting the sampling bridge of Tektronix electrical sampling modules from damage due to electro-overstress (EOS) and electro static discharge (ESD) where large static charges can be stored in the DUT.

The P8018 provides a unique probe tip pressure actuating feature and control circuit which, used with the matching 80A02 EOS/ESD Protection Module, enables a superior technique and performance capability for electrical sampling module EOS/ESD protection of acquired electrical signals and TDR measurements.
