Tests and Adjustments PNA Series Microwave Network Analyzers
Before You Begin N5230A
Before You Begin
Before checking, verifying, or adjusting the analyzer, refer to the following paragraphs to:
• make sure the operating environment is within its requirements
• make sure that proper electrostatic discharge (ESD) protection is provided
• make sure the analyzer has warmed up properly to achieve system stability
• review the principles of connector care
Verify the Operating Environment
Due to their operating specifications, the verification and calibration kit devices determine
your operating environment conditions. Open the calibration and verification kits and
place all the devices on top of the foam inserts so they will reach room temperature. As the
device dimensions change with temperature, their electrical characteristics change as well.
It is necessary to keep the environmental levels within the limits stated in the PNA Series

Protect Against Electrostatic Discharge (ESD)
This is important. If not properly protected against, electrostatic discharge can seriously
damage your analyzer, resulting in costly repair.
CAUTION
To reduce the chance of electrostatic discharge, follow all of the
recommendations outlined in “Electrostatic Discharge Protection” on
page 1-6, for all of the procedures in this chapter.
Allow the Analyzer to Warm Up
NOTE
To achieve the maximum system stability, allow the analyzer to warm up for
at least 90 minutes.
