Trigger Out BNC

This chassis-referenced digital output can be programmed to supply a pulse output at the leading or trailing edge of a step or pulse, or at the leading edge of any point in a list sequence. The output signal is nominally a 10 microsecond low-true pulse. To enable the Trigger Out connector, use:

OUTPut:TTLTrg:STATe ON

At *RST, the Trigger Out connector is off.

To select a trigger source for the Trigger Out connector, use:

OUTPut:TTLTrg:SOURce BOT EOT LIST

BOT - specifies that the pulse is output at the beginning of a transient. This is the *RST setting. EOT - specifies that the pulse is output at the end of a transient.

LIST - specifies that the pulse position is defined by the LIST:TTLTrg command.

You can also specify the Trigger Out connector as a trigger source for measurement trigger sequences. Use:

TRIGger:SEQuence3:SOURce TTLT or

TRIGger:ACQuire:SOURce TTLT
