Page 10: Installation
Installation Introduction System 40 Custom Coaxial RF Signal Routing Systems provide an integrated signal routing solution designed and built to cus- tomer specifications. The System 40 typically includes a Keithley Model 7001 or 7002 switch control unit, microwave coaxial switches, a power supply, and a 19-inch rack mount assembly. The IEEE-488 compatible switch controller operates the coaxial switches and provides an easy to read display of switch status. -

10-32x5/8 PPH panel to rails. Parts list Table 1-1 lists the supplied parts required to rack mount a typical System 40 chassis. Rack preparation 1. Select a location in the rack. 2. Hold up the system at the selected location in the rack. The four slotted mounting holes in the front panel dictate the location of the captive nut fasteners on the front rack rails. -

Shelf mount Rack preparation 1. Select a position in the rack. In most cases, the weight of the System 40 dictates a position in the lower half of the rack. The System 40 typically takes up 10.5” of vertical space. - Page 13 7020-MWS\QCC switch card, installed in the 7001/2 mainframe, to the System 40 chassis mounted RF switch terminals using a ribbon cable terminated with a 96-pin DIN connector. One piece System 40’s may be shipped from the factory with this cable connected, two piece systems must be connected after rack installation. The ribbon cable 96-pin DIN connector label identifies the mating 7020-MWS connector.

Page 14: Operation
Operation Introduction System 40 Custom Microwave Switch Systems are derived from the Keithley Model 7116-MWS. Because each System 40 is unique, the 7116-MWS will be used to represent a typical configuration for switch system operating principles and troubleshoot- ing procedures. -
Page 15: Operating Instructions
Operation Operating instructions To select an input channel, the Model 7001 must close two switches at the same time. Table 2-1 lists which Model 7020-MWS digital outputs must be activated to select each respective RF input. The table also shows 7001 channels used to select the inputs. Table 2-1 Model 7001 channels and memory locations for 1x16 multiplexer 7020-MWS Digital Outputs... -
Page 16: Switch Life
The life of a switch is usually specified in cycles, that is the number of times it switches from one position to another and back. System 40 RF switches have lives from one-million to ten-million (1,000,000 to 10,000,000) cycles per switch position without noticeable performance degradation. -
