85058B/E 1-5
General Information
Calibration Kit Overview
• 6.3 mm offset short has 2 rings or bands and is identified as Short 2
• 7.12 mm offset short has 3 rings or bands and is identified as Short 3
• 7.6 mm offset short has 4 rings or bands and is identified as Short 4
• offset open has 1 ring and is designed to be 180 degrees out of phase with Short 1. In
addition, the offset open has a rounded edge to help distinguish it from the shorts (see
Figure 1-1 ).

Adapters
Like the other devices in the kit, the adapters are built to very tight tolerances to provide good
broadband performance and to ensure stable, repeatable connections.
85058E (Economy) Kit Contents
The 85058E (Economy) calibration kit contains the following:
• one pair (male and female) of an offset open, offset short, and a broadband termination
• three adapters
• a 5/16 inch, 90 N-cm (8 in-lb) torque wrench for use on the 1.85 mm connectors
• an open–end wrench for the 8 mm flats on some of the components
Refer to Table 6-1 on page 6-3 and Figure 6-2 on page 6-7 for a complete list of kit contents
and their associated part numbers.
Broadband Terminations
The broadband terminations are instrument-grade, 50

terminations that have been optimized
for performance up to 67 GHz. The rugged internal structure provides for highly repeatable
connections. A distributed resistive element on sapphire provides excellent stability and return
loss. The smooth body of the broadband termination allows it to be easily distinguished from an
open and short.
Offset Opens and Shorts
The opens and shorts are built from parts that are machined to the current state-of the-art
precision machining.
The short’s inner conductors have a one-piece construction, common with the shorting plane.
