During Program Execution
When you execute a program, the trigger busy signal is set to low level, and the source
level changes. The source change completion (Ready) signal, which is a low-level pulse
signal, is generated 10 ms after the source level changes. When each program interval
time completes, the trigger busy signal is set to high level. The program proceeds from
step to step by repeating this pattern.

Output ON/OFF (See section 5.5 for the procedure)
There are two output modes: OFF or ON.
OFF: The output is disconnected, and the specified source level is not generated. In
this mode, program and measurement functions are disabled.
ON: The output is connected, and the specified source level is generated. In this
mode, program and measurement functions are enabled.
Note
A mechanical relay operates when the GS200 switches between output on and output off. Note
the following points when using the GS200.
• It takes approximately 20 ms for the relay to stabilize.
• As the number of on/off operations increases, effects begin to appear such as the relay
taking longer to stabilize. Though dependent on the load, the electrical life of the relay is
around 100,000 operations.
DUT Protection Using Limiters (See section 5.4 for the procedure)
CAUTION
If a current source that exceeds the current limiter setting is connected in voltage
source mode; if a voltage source that exceeds the voltage limiter setting is
connected in current source mode; or if a load that exceeds the source range listed
above is connected, an abnormal load is detected, and the output is turned off (the
output trips). Do not connect these types of loads to the GS200. Doing so may
damage the instrument.
Voltage Limiter and Current Limiter
If a limiter is set, an additional limit can be placed within the source range. This limit can
prevent damage to the connected device due to overcurrent or overvoltage. In voltage
source mode, the current limiter is enabled. In current source mode, the voltage limiter is
enabled.
