PXI-2799 Specifications

These specifications apply to the PXI-2799.

All specifications are subject to change without notice.

Notice The protection provided by the PXI-2799 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 Specifications 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.

Caution The protection provided by the PXI-2799 can be impaired if it is used in a manner not described in this document.

PXI-2799 Pinout

Use the pinout to connect to terminals on the PXI-2799.

Table 1. Signal Descriptions
Signal	Description
COMx	Routing destination for corresponding signal connections
NCx	Normally closed signal connection
NOx	Normally open signal connection

Input Characteristics

Maximum voltage (cold-switching only)

30 V_rms

Caution Do not switch active RF signals. As a relay actuates, the channel is momentarily unterminated. Some RF sources can be damaged by reflections if their outputs are not properly terminated. Refer to your RF source documentation for more information.

Maximum carry current (per channel)	0.6 A_rms
Maximum RF carry power (50 Ω load)	18 W

Note The switching power is limited by the maximum switching current and the maximum voltage. Channel to common switching power must not exceed 18 W.

Note National Instruments recommends against switching RF signals below -35 dBm with this device.
