Keithley 7001 Specs
Capacity: 2 plug-in cards per mainframe.
Memory: Battery backed-up storage for 100 switch patterns.
Switch Settling Time: Automatically selected by the mainframe for each card. Additional time from 0 to 99999.999 seconds can be added in 1ms increments.
External Trigger (TTL-compatible, programmable edge, 600ns mini-mum pulse, rear panel BNC).
IEEE-488 bus (GET, *TRG)
Manual (front panel)
Internal Timer, programmable from 1ms to 99999.999 seconds in 1ms increments.
Status Output: Channel Ready (TTL-compatible signal, rear panel BNC). Low going pulse (10µs typical) issued after relay settling time. For two different switch cards, 7001 will be set to the slowest relay settling time.
Switching Sequence: Automatic break-before-make.
Mainframe Digital I/O: 4 open-collector outputs (30V maximum pull up voltage, 100mA maximum sink current, 10 output impedance), 1 TTL compatible input, 1 common.
Relay Drive: 700mA maximum for both card slots.
Card Compatibility: Fully compatible with all 7XXX cards.
