Except for the
last SMU,
SMUs start the
source value
output. And
SPGUs and the
last SMU start
the base value
output. The

After the base hold
time, the last SMU start
the source value output
and SPGUs start pulse
output simultaneously.
SMUs continue the source
value output and SPGUs
continue pulse output until
the specified time elapses
or the repeat count reaches
the specified number.
After that, the last SMU
outputs the base or source
value set by the Output
Value after Measurement,
and SPGUs output the base
value.
If the bias
hold
function is
ON, all
source
channels
continue
the output.
Else, all
source
output
goes to 0 V
in the

definition.
Free run The last SMU outputs the
base or source value set by
the Output Value after
Measurement, and SPGUs
continue pulse output.
If the bias hold function is
OFF, SPGUs output the
base value.

After the specified time
elapses or the repeat

The last SMU outputs the
base or source value set by
the Output Value after
Measurement, and SPGUs
output the base value.
