Operator's Check

Tip: Use Move App to Back to cause the VNA application to move behind this application on the screen.

Overview

The Operator's Check should be performed when you first receive your VNA, and any time you wish to have confidence that the VNA is working properly.

Notes

  • The Operator's Check does not verify performance to specifications. To verify VNA performance to specifications, run System Verification.

  • Allow the VNA to warm up for 30 minutes before considering a failed test to be valid.
