At Creativeit Group we have calibration kits for network analyzers.
We have this HP 85050C precision calibration kit, which contains precision calibration standard devices (including an airline) to characterize the systematic errors of network analyzers at the 7 mm interface. This kit also contains adapters to change the gender of the test port, connector gauges to check and maintain the connector interface, and a torque wrench for proper connection.
• Frequency range from DC to 18 GHz
• Standards for performing a full two-port calibration
• 50-ohm precision airline for Thru-Reflect-Line (TRL) calibration
• Torque wrenches to connect the standards correctly
• Adapters to change the gender of the test port
