4.6.6 Trigger Signal
The trigger signal can be used as a synchronous signal to observe waveforms generated by the switching operation on
the oscilloscope. This signal is also used to remove a pause from the sequence operation.
(a) Trigger signal output
The trigger signal is output from J1 terminals 3 and 4 on the rear panel and the TRIG OUT terminals on the
subpanel.(See the figure below.)
The trigger signal is output when:
• the trigger output is specified in the sequence operation,
• a signal is input to the trigger input terminals,
• the “GET” command is input to GPIB, or
• the trigger signal is set to be output by a switching operation.

NOTE
The trigger signal is characterized by an output voltage of about 3.5 V, pulse width of not less than 5 µ s, and
output impedance of about 10 k Ω . The trigger output terminals are isolated from any other terminals.
(b) Trigger signal input
The trigger signal is input to J2 terminals 3 and 4 on the rear panel. When the signal voltage, whose maximum
allowable voltage is 6 V and pulse width is not less than 20 µ s, is input to these terminals, the load unit can be
synchronized with another load unit (see the figure below).

NOTE
When the pulse input to the trigger signal input terminals rises, the trigger signal is generated on the
trigger signal output terminals. The input terminals are connected to COM via about 100 k Ω resistance,
and the maximum allowable voltage is 6 V. The operating threshold level is TTL.
