Keithley 7002 Switch/Control Mainframe

Keithley 7002 Switch/Control Mainframe

Specifications

• Capacity: 10 plug-in cards per mainframe.
• Memory: Battery backed-up storage for 500 switch patterns.
• Switch Settling time: Automatically selected by the mainframe. For different switchcards, 7002 will be set to the slowest relay settling time. Additional time from 0 to 99999.999 seconds can be added in 1ms increments.
• Trigger Sources: External Trigger (TTL-compatible, programmable edge, 600 ns minimum pulse, rear panel BNC).IEEE-488 bus (GET, *TRG)

Trigger Link

• Manual (front panel)
• Internal Timer, programmable from 1.0ms to 99999.999 seconds in 1.0ms increments.
• Status Output: Channel Ready (TTL-compatible signal, rear panel BNC). Low going pulse (10µs typical) issued after relay settling time.
• Switching Sequence: Break-before-make (programmable).
• Mainframe Digital i/o: Four open collector outputs (30 V maximum, 100 mA maximum sink current, 10? output impedance), one TTL compatible input, one common, one +5 V.
• Relay Drive: 3.5 A maximum for all 10 card slots.
• Card Size: 32 mm high × 114 mm wide × 272 mm
• Card Compatibility: Fully compatible with all 7001 cards
• Signals: Four 3-pole rows (Hi, Lo, Guard). These signals provide matrix and multiplexer expansion between cards within one mainframe.
• Maximum Voltage: 250 V DC, 250 V rms, 350 V AC peak
• Maximum Current: 1 A peak.
• Channel Crosstalk: < -65 dB @ 1MHz (50? load).
• Bandwidth: <3 dB loss at 100MHz (50? load)
