Before You Begin
Before checking, verifying, or adjusting the analyzer, refer to the following
paragraphs to:
— Make sure the operating environment is within 19 to 27 °C and 5 to 95%
humidity.
— Make sure that proper electrostatic discharge (ESD) protection is provided.
— Review the principles of connector care.
Protect Against Electrostatic Discharge (ESD)
This is important. If not properly protected against, electrostatic discharge can
seriously damage your analyzer, resulting in costly repair.
Allow the Analyzer to Warm Up
Before testing or adjusting the FieldFox analyzer, allow it to warm up as
described under “DUT Warmup” in the “Getting Started” section of the N7841A
help file.
Review the Principles of Connector Care
Proper connector care and connection techniques are critical for accurate and
repeatable measurements. Refer to Table 3-1 for tips on connector care.
Prior to making connections to your analyzer, carefully review the information
about inspecting, cleaning, and gaging connectors. Refer to the calibration kit
documentation for detailed connector care information.
For course numbers about additional connector care instruction, contact
Keysight Technologies. Refer to “Contacting Keysight” on page 28.
To reduce the chance of electrostatic discharge, follow all of the recommendations outlined in
“Electrostatic Discharge Protection” on page 12 for all of the procedures in this chapter.
