6.7 Set Programmable Pulse Mode 45
6.7.7 Prog Pulse – Pulse Polarity
Use “Pulse Polarity” to change the pulse’s OFF-to-ON behavior as follows:
1. Positive: the voltage is held low (0 Vdc) when the pulse is off and transitions high (5 Vdc)
when on.
2. Negative: the voltage is held high (5 Vdc) when the pulse is off and transitions low (0 Vdc)
when on.
To set up the pulse polarity, first set up the programmable pulse mode (e.g. Single Trigger) and then
go back into the Prog Pulse menu and set up the polarity separately.
RS-232C: see Section 9.2.10 .
