Explanation
DC Source Mode
If the sweep mode (see section 2.6, “Sweep”) is ON in DC source mode, the source level
changes after a time specified by the source delay elapses from the point in which the
trigger is activated. Then, measurement starts after a time specified by measurement
delay elapses. When the measurement and computation are complete, one source
measure cycle is finished.
However, if you change the source level with a key or a communication command in the
middle of a source measure cycle, the source level changes immediately without waiting
for the source delay or measure delay, and the internal trigger phase is reset.
If the sweep mode is OFF, the source level is maintained, and the source measure cycle
is carried out.
If the measurement function is turned OFF (see section 2.4, “Measurement”), measure
delay, measurement, and computation are not carried out. The time when the source
level changes is the end of the source measure cycle.

Note
The output capacitance indicated below exists between the Hi OUTPUT and Lo OUTPUT
terminals of the GS610. This capacitance produces the following effects.
• If the load changes drastically such as when a short circuit occurs when generating
voltage, a large transient discharge current is generated from the output capacitance.
• If a voltage source (power supply, amplifier, signal generator, etc.) is connected as a load,
the load voltage source may be unstable due to the output capacitance.
• Take the time it takes for the output capacitance to be charged and discharged when
determining the response time of the source voltage.
