Visit ni.com/manuals for the most current specifications. Topology ........................................................... 2-SPDT Refer to the NI Switches Help for detailed topology information. To ensure the specified EMC performance, operate this product only with shielded cables and accessories. Caution Caution Device relays might change state momentarily during electrostatic discharge. Caution Refer to the Read Me First: Safety and Electromagnetic Compatibility document at ni.com/manuals for important safety and compliance information. About These Specifications Specifications characterize the warranted performance of the instrument under the stated operating conditions. Typical Specifications are specifications met by the majority of the instrument under the stated operating conditions and are tested at 23 °C. Typical specifications are not warranted. Input Characteristics Maximum voltage............................................. 30 Vrms (cold switching only) Caution Active RF signals must not be switched. 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 .................................... 0.6 Arms (per channel) Maximum RF carry power ............................... 18 W (50 Ω load) The switching power is limited by the maximum switching current and the maximum voltage. Channel to common switching power must not exceed 18 W.
