Check
Do not connect any equipment other than the FG410 and FG420 not specified
by YOKOGAWA to the frequency reference output.
The special signal that is output from this terminal during synchronization may
make the operation of such connected equipment unstable.
3.2.7 Multi-I/O ( MULTI I/O)
FG420 FG410
MULTI I/O MULTI I/O
MULTI I/O can be used for sweep control and sequence control. It outputs the step synchronization
code for the sequence.
Control input for sweep oscillation mode
The following types of control for sweep oscillation can be done with 3-bit logic input.

p. 98
Start Start the sweep from the start through fall input.
ORed with external trigger input.
Stop Stop the sweep through fall input.
Hold/resume Hold the sweep through fall input during sweep execution.
The sweep is resumed from where it was held through rise input during hold.
Control input for sequence oscillation mode
The following types of control for sequence oscillation can be done with 4-bit logic input.

“6.2 Basics” in the Application Instruction Manual
Start or state branch Start control and state branch control can be selected.
During start control, the sequence is started from the beginning through fall input.
ORed with external trigger input.
During state branch control, the sequence is branched to the specified destination
step through low level input upon step completion.
Stop Stop the sequence through fall input.
Hold/resume Hold the sequence through fall input during sequence execution.
The sequence is resumed from where it was held through rise input during hold.
Event branch The sequence is branched to the specified destination step through fall input.
In the sequence oscillation mode, the 4-bit step synchronization code specified for each step is output.
