E7495A/B Base Station Test Set Specifications

Specifications describe the test set's warranted performance and are valid over the
entire operating/environmental range unless otherwise noted.

The E7495A/B Base Station Test Set has been tested to the specifications of IEC
529 “Degrees of Protection Provided by Enclosures (IP Code).” Using this standard,
the E7495A/B is rated IPX4.

Supplemental Characteristics are intended to provide additional information useful
in applying the test set by giving typical, but non-warranted performance
parameters.

Characteristics and specifications are shown as follows:

• Bold type indicates a warranted, hard specification.

• Normal type indicates a nominal value. Nominal values are design center values
and not normally tested during manufacturing.

Supplemental characteristics are intended to provide additional information useful
in applying the instrument by giving typical, but non-warranted, performance
parameters. These characteristics are shown in italics or labeled as “typical,” or
“usable to”.
