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

well-ventilated area. Allow all residual alcohol moisture to evaporate, and the fumes to dissipate prior to
energizing the instrument.
