Condition: Used

This Anritsu WR137M waveguide calibration kit covers 5.85 to 8.20 GHz and provides all the precision standards required for SSLT (Offset-Short, Short, Load, Thru) VNA calibration over the WR137 / WG14 waveguide band. The kit includes metric-series components with individual serial numbers (23UM70 S/N 148664-F, 24UM70 S/N 195851-F, 26UM70 S/N 194860-F, 35UM70N S/N 194635-F), stored in a foam-lined hard carry case.

What is included:
• 23UM70 — 1/8 Offset Short (6.90 mm), S/N 148664-F
• 24UM70 — 3/8 Offset Short (20.71 mm), S/N 195851-F
• 26UM70 — Precision Low Power Termination (Load), S/N 194860-F
• 35UM70N — Precision Waveguide-to-Coaxial Adapter (N-type), S/N 194635-F
• Hard carry case with custom blue foam insert

Please note that we have multiple units in stock, and the images presented are of one of them, therefore the cosmetic condition of the exact item you will receive may slightly differ.

The Anritsu WR137M Waveguide Calibration Kit provides all the precision components and tools required to calibrate a Vector Network Analyser (VNA) or Vector Network Measurement System (VNMS) for accurate, 12-term error-corrected S-parameter measurements in the WR137 waveguide band.

The kit supports the Offset-Short, Short, Load, Thru (SSLT) calibration method, which is the standard approach for waveguide line types. The 23 Series 1/8 offset shorts and 24 Series 3/8 offset shorts are banded waveguide components specifically designed for waveguide calibrations. The 35U Series precision waveguide-to-coaxial adapter transforms the standard WR137 waveguide interface to a coaxial N-connector, enabling convenient microwave coaxial measurements alongside waveguide measurements. The 26UM70 precision termination provides a metrology-grade matched load standard.
