PXI-2535 Specifications

These specifications apply to the PXI-2535 .

All specifications are subject to change without notice.

Notice The protection provided by the PXI-2535 can be impaired if it is used in a manner not described in this document.

About These Specifications

Specifications characterize the warranted performance of the instrument under the stated operating conditions. Data in this document are Warranted unless otherwise noted.

Typical Specifications are specifications met by the majority of the instrument under the stated operating conditions and are tested at 23 °C ambient temperature. Typical specifications are not warranted.

All voltages are specified in DC, AC_pk, or a combination unless otherwise specified.

Notice To ensure the specified EMC performance, operate this product only with shielded cables and accessories.
