Keithly 708A Switching Matrix Mainframe Matrix testing This appears to be brand new The manual still is shrink wrapped. It is in original box. I opened it to plug it in powers up! The high-density single-slot Model 708A Switching Matrix builds upon the strengths of the original Model 708 to offer even greater capabilities for production testing in industrial environments. For example, the Model 708A requires only 31⁄2inches of vertical space in a standard 19-inch rack, so it’s easy to fit into virtually any testing setup. The Model 708A is compatible with all existing DC and RF switch cards for the original Model 707 and 708 switch mainframes. This card line offers both general-purpose and application-specific cards for use in semiconductor and telecommunica- tions testing. There’s even a Universal Adapter Card that provides access to the digital and analog backplanes, as well as a prototyping area for custom circuit designs. The Model 708A can control up to 96 channels (expandable to 480) from the front panel to simplify test development. Sixteen chan- nels of digital I/O allow the operator to control and read-back the state of other equipment in the Optimized for Industrial Production Testing Environments The Model 708Ahas been specifically engineered so that it does not require ventilation holes or an inter- nal fan. This design makes the 708Aideal for automated production test applications in harsh industrial environments. Dust and other contaminants are sealed outside the enclosure, minimizing the potential for equipment failures. Eliminating the fan also makes the 708A suitable for cleanroom applications. In many production test applications, it’s desirable to locate the switching matrix as close to the device under test as possible. With the 708A, test engineers have the option to install the switching card through the rear panel or through the front panel, which can simplify connections and shorten the amount of wiring required. This also makes maintenance easier because it offers access to the card and connections from the front of the rack. • Optimized for industrial • Requires just 31⁄2 ̋ of rack space • Low heat producing design — no • Card accessible from either front • Front panel relay status display • “One touch” programming • Control up to 96 channels of • Compatible with a wide range of CARD INSTALLATION: Configurable for front or rear installation.
