Initial Instrument Functionality Check

Power on the instrument and allow the instrument to boot up. Run an alignment and display the

measurement screen. (The instrument will probably display a spectrum analyzer screen and you will

see the instrument sweeping.)

There should be no alignment failures. If there are failures, investigate and fix the problem before

continuing.

Before you disassemble the instrument, turn the power switch to Standby. After the instrument

has completely shut down, unplug the instrument. Failure to unplug the instrument can result in

personal injury.

Electrostatic discharge (ESD) can damage or destroy electronic components. All work on

electronic assemblies should be performed at a static-safe workstation. Refer to the

documentation that pertains to your instrument for information about static-safe workstations

and ordering static-safe accessories.
