A GREATER MEASURE OF CONFIDENCE
Plug-in RF switching module for Integra mainframes
SWITCH/MEASURE SYSTEMS
7711 2GHz 50ΩRF Module
• Outstanding signal routing
performance to 2GHz
• Dual 1x4 configuration
• Rear panel SMA connections
• On-board switch closure
counter
• On-board S-parameter storage
• Switch up to 60VDC
The Model 7711 2GHz RF module is part of Keithley’s Integra Series of flexible
measurement/control solutions. This new module is designed to plug into
either the two-slot Model 2700 or five-slot Model 2750 mainframe, adding RF
signal routing capability to the Integra Series’ robust DC switch and measurement performance. This module’s outstanding low frequency performance
and low cost make it useful for a wide variety of applications, including switching power supply ripple testing.
The Model 7711’s outstanding high frequency performance and on-board
S-parameter storage make it ideal for routing RF signals to instrumentation
and devices with bandwidths up to 2GHz. Its addition to the Integra Series
allows users to build cost-effective, high performance hybrid DC/RF systems
simply and economically. Like every Integra Series module, the Model 7711
has on-board switch closure counters that can be used to track relay life, simplifying preventative maintenance in production test applications.
