Executing Programs (See section 6.7 for the procedure)
Operations When the Program Trigger Is Set to Norm
You can use the RUN, STEP, and HOLD keys and external triggers to control the
program execution. The program interval time specifies the execution interval for each
step in the program.
When you press the HOLD or STEP key, the trigger busy (TrigBusy) and source change
completion (Ready) signals change as shown in the following example.
Program Setup Example
Step 1: 1 V
Step 2: 2 V
Step 3: 3 V
Program Conditions
• Repeat mode is off.
• Program interval time is 5 s.
• Program slope time is 3 s.
Ts: Program slope time
Ti: Program interval time

The low pulse that indicates source change completion (Ready) is generated 10 ms after Ts elapses.
HOLD and STEP
When you press the HOLD key to pause program execution, the paused step is said
to be in the “mid-execution” state. If you press the STEP key while the GS200 is in this
state, the current step that was in the mid-execution state is re-executed. When this step
completes, the GS200 pauses the program again. If, on the other hand, you press the
HOLD key while the GS200 is in this state, the GS200 continues program execution from
the point that it was paused in the step that was in the mid-execution state.
For example, assume that we have a program that begins at 0 V and ends at 10 V. Each
step specifies an increase of 1 V, and a step is executed each second. Now assume that
we execute the program and press HOLD when 4 V has been generated for only 0.5
seconds.
• If the STEP Key Is Pressed
The GS200 does not generate 5 V as specified by the next step, but rather generates
4 V for 1 second as specified by the step that was in the mid-execution state, and then
pauses execution again. If you press the STEP key once more, 5 V is generated for 1
second, and then the program execution is paused again.
