TCS50 Calibration Substrate

An S-parameter calibration substrate with short, open and load standards for vector network analyzer. 

The substrate supports all Agilent PNA and ENA calibration to remove probe and probe tip contact errors. It allows users to move the measurement reference point all the way to the probe tip. This substrate standard can also be used to set impedance reference for Agilent ENA to within 0.5% accuracy.

For S-Probes with probe pitches larger than 1.0 mm, please contact PacketMicro to order TCS50 substrate, which has long patterns to support wider pitches and costs $400, same as TCS60.


  • Substrate: Polished alumina
  • Impedance: Open, short, through, 50 Ω, 100 Ω single-ended standard
  • Contact material: Gold
  • Accuracy: 50 Ω < 0.5%, 100 Ω < 1%
  • Pitch Spacing: 0.2 mm to 1.0 mm
  • Part Number: TCS60
  • Availability: now


  • Support S-parameter calibration and impedance validation for engineering and manufacturing probing.
  • Wide pitch range for single-end probes
  • High accuracy and cost effective solution
  • Suitable for Agilent, Rohde & Schwarz and Anritsu network analyzers

TCS10 TDR Calibration Substrate

TCS10 Calibration Substrate

TCS10 a calibration substrate with short and load standards for TDR impedance validation. It allows users to identify the impedance inaccuracy caused by the test instrument and cables. TCS10 is perfect for used with BladeProbe and any other TDR probes.  This substrate standard can be used to set impedance reference of any TDRs to within 0.5% accuracy.


  • Substrate: ceramic
  • Impedance: Short, through, 50 Ω, 85 Ω, 100 Ω and 50 Ω differential mode standard
  • Contact material: Hard gold
  • Accuracy: < 0.5%
  • Pitch Spacing: 1 mm/0.8 mm/0.5 mm/ 0.4 mm
  • Part Number: TCS10
  • Availability: now
