Model DMM7510 7½ Digit Graphical Sampling Multimeter Reference Manual
Input characteristics:
•
The falling edge is detected as the external drive pulses the line low, and the internal drive
latches the line low.
Output characteristics:
•
In addition to trigger events from other trigger objects, the TSP commands
trigger.digout[N].assert() and trigger.tsplinkout[N].assert()
•
The physical line state does not change until all drives (internal and external) release the line.
