General Purpose SwitchModulesMost VXI test environmentsrequire general purpose switchingcapabilities to enable and disableparticular I/O circuits, especiallyduring fault analysis routines andsubroutines. ASCOR generalpurpose switch modules are idealfor low frequency switching andpower switching applications.These VXI Switching Modules aretailored for maximum flexibilityfor system integration. The modulesare all C-size with up to 96 SPSTForm A relays rated at 5 amps 250VAC, as well as 48 SPST relaysrated at 10 amps 250 VAC or 48SPDT relays rated at 5 amps 277VAC, each meeting requirementsfor high current switching in ATEsystems. They are the industry’shighest density general purposeswitches and include Models3000-2, 3000-12, 3000-42, 3000-43and 3000-53/53A.Shielded Relay Scanner& Matrix ModulesASCOR’s shielded relay scanners,such as the Model 3000-3and 3000-8, are ideal for generalscanning purposes, includingDigital Multi-Meters (DMMs).Using shielded relays in scanneror multiplexer applications wherethere are a large number ofchannels will provide excellentsignal isolation and low crosstalkcharacteristics. Channels areindividually controlled for maximumversatility. When usingshielded relays, ASCOR coaxiallyties the relay shields to a separateanalog ground plane in order toensure minimal crosstalk andsignal interference.The switch matrix modules areavailable from combinations of2x128 single-wire (3000-34) to2x128 (3000-44), 4x64 two-wire(3000-45) and 8x32 two-wire(3000-47). Bandwidths rangefrom a low of >40 MHz to a highof >90MHz ensuring a low noiseenvironment. If crosstalk is nota major concern, most of theshielded modules are also availablewith non-shielded relays.High Frequency Shielded CoaxSwitchesASCOR offers a variety of HighFrequency Coax Switches. All ofthe Coax Switch VXI modulesuse internally cabled switch pathat 50 ohms. Also available uponrequest is a 75 ohm switch path.The ASCOR Coax Switchesinclude matrices from 2x32 at>350 MHz for the worst path(3000-5) to 1x8 multiplexers at>500 MHz (3000-32). Theseswitch modules are ideal for usewith oscilloscopes, frequencycounters and other instrumentsthat require clean coax signals.
