Introduction

Environmental Requirements

3. A packaged item supplied with the analyzer is missing.
4. A fault has been detected in the subsequent operation check of the
Environmental Requirements
Set up theE4990A where the following environmental requirements are met.

Operating Environments

Ensure that the operating environment meets the following requirements.
Temperature
Temperature range at
the error-correction
Humidity
Altitude
Vibration
Above environmental requirements are NOT for the specifications and
measurement accuracy of the analyzer, but for the operating environment
of the analyzer.

Ventilation Requirement

To ensure safety requirements, the specifications and measurement accuracy
of the analyzer, you must keep the environmental temperature within the
specified range by providing appropriate cooling clearance around the analyzer
or, for the rack mount type, by forcefully air- cooling inside the rack housing.
For more information on environmental temperature to satisfy the
specifications and measurement accuracy of the analyzer, see the specification
in the E4990A Datasheet.
When the environmental temperature around the analyzer is kept within the
temperature range of the operating environment specification (See Section
"Operating Environments" on page

If an abnormality is detected in step 1, contact the company that
transported the analyzer as well as your nearest Keysight Technologies
sales and service office.
