Agilent Technologies 6812B, 6834B Remote Inhibit and Discrete Fault Indicator, Trigger Out BNC

Programming Examples - 4

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

		OUTP:TTLT:STAT
OUTP:TTLT:SOUR		OFF

Remote Inhibit and Discrete Fault Indicator

The remote inhibit and discrete fault indicators are implemented through the respective INH and FLT connections on the rear panel. Refer to "Operating Characteristics" in appendix A of the User’s Guide for the electrical parameters.
