4.11.4 External Trigger Output
OUTPut:TTLTrg:MODE
This command sets the operation of the Trigger Out signal to either Function Strobe or
Trigger mode. Note that on Series II MX/RS/BPS system having firmware revision 4.00 or
higher, factory default is Trigger state which means the OUTP:TTLT:STAT command is
required to generate outputs. On Series I MX units having firmware 1.00 or higher, default
mode is FSTR. This command does not apply to Series I units. On Series I units, the
OUTPUT:TTLT 1 command will force the mode to trigger output mode. In Function Strobe
mode, an output pulse is generated automatically any time an output parameter such as
voltage, frequency or phase is programmed. The AC source Trigger Out signal is available
at the BNC connector on the rear of the power source.
Note that the desired mode must be set after turning on the power source as it is not
retained as part of the INIT subsystem.

OUTPut:TTLTrg[:STATe]
This command enables or disables the Trigger Out signal, which is available as a BNC
connector on the rear panel of the AC/DC source. This signal is the same as the Function
Strobe BNC output on the rear panel. If the Trigger Out state is OFF (0), these outputs
operate as a function strobe. If the Trigger Out state is ON (1), an output is generated only
when a 1 is placed in the TTLTrigger list.
Refer to the User Manual for pin out information and signal levels for the Trigger out or
Function Strobe signal. signal.)

This command selects the signal source for the Trig Out signal as follows:
• BOT
Beginning of transient output
• EOT
End of transient output
• LIST
Specified by the TTLTrg list
When an event becomes true at the selected TTLTrg source, a pulse is sent to the the
function strobe on the system interface connector on the rear panel of the AC/DC source.
