Keithley 7002 Switch/Control Mainframe
The Keithley Model 7002 Switch System is a 10-slot mainframe that supports up to 400 2-pole multiplexer channels or 400 matrix crosspoints. The front panel includes a unique interactive display of channel status for quick programming. Scanning speeds of up to 300 channels per second are possible with the high density switch cards. The wide selection of more than 30 different switch cards makes the 7002 one of the most flexible switching mainframes available.

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)
