utput characteristics:
• In addition to trigger events from other trigger objects, the TSP commands
trigger.digout[N].assert() and trigger.tsplinkout[N].assert() also trigger
events.
• The physical line state does not change until all drives (internal and external) release the line.
• Action overruns occur if the internal drive is not latched low and a source event is received.

Connecting the 2470 to a Trigger Link system
Trigger Link (TLINK) is a Keithley Instruments proprietary trigger bus that is available on many
Keithley Instrument products. The 2470 supports TLINK systems. You can connect the 2470 to a
TLINK system using the Model 2450-TLINK Trigger Link Cable. Configure the appropriate 2470 digital
I/O lines as open-drain inputs or outputs for compatibility with TLINK.
