PXI-2597 Specifications

PXI-2597 Specifications

These specifications apply to the PXI-2597.

All specifications are subject to change without notice.

Notice The protection provided by the PXI-2597 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, ACpk, or a combination unless otherwise specified.

Caution The protection provided by the PXI-2597 can be impaired if it is used in a manner not described in this document.

Input Characteristics

Caution Use precaution when using the PXI-2597 to avoid electrical shock.
Caution This module is rated for Measurement Category I and intended to carry signal voltages no greater than 100 V. This module can withstand up to 500 V impulse voltage. Do not use this module for connection to signals or for measurements within Categories II, III, or IV. Do not connect to MAINs supply circuits (for example, wall outlets) of 115 or 230 VAC.
Caution When hazardous voltages (>42.4 Vpk/60 V DC) are present on any channel, safety low-voltage (≤42.4 Vpk/60 V DC) cannot be connected to any other channel.
