Caution
Network Analyzer
Do not exceed the operating input power, voltage,
and current level and signal type appropriate for the
instrument being used, refer to your instrument's Function
Reference.
Electrostatic discharge (ESD) can damage the highly
sensitive microcircuits in your instrument. ESD damage is
most likely to occur as the test fixtures are being connected
or disconnected. Protect them from ESD damage by wearing
a grounding strap that provides a high resistance path to
ground. Alternatively, ground yourself to discharge any static
charge built-up by touching the outer shell of any grounded
instrument chassis before touching the test port connectors.
