85058B/E 1-5General InformationCalibration 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. Inaddition, the offset open has a rounded edge to help distinguish it from the shorts (seeFigure 1-1).Figure 1-1 OPEN Calibration Devices: 85058B and 85058EAdaptersLike the other devices in the kit, the adapters are built to very tight tolerances to provide goodbroadband performance and to ensure stable, repeatable connections.85058E (Economy) Kit ContentsThe 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 componentsRefer to Table 6-1 on page 6-3 and Figure 6-2 on page 6-7 for a complete list of kit contentsand their associated part numbers.Broadband TerminationsThe broadband terminations are instrument-grade, 50terminations that have been optimizedfor performance up to 67 GHz. The rugged internal structure provides for highly repeatableconnections. A distributed resistive element on sapphire provides excellent stability and returnloss. The smooth body of the broadband termination allows it to be easily distinguished from anopen and short.Offset Opens and ShortsThe opens and shorts are built from parts that are machined to the current state-of the-artprecision machining.The short’s inner conductors have a one-piece construction, common with the shorting plane.
