To Optimize the Source/Measurement Wait Time
If measurement speed is given top priority or is more important than reliability, set
the wait time shorter by using the WAT command. The source wait time is the time
the source channel always waits before changing the source output value. The
measurement wait time is the time the measurement channel always waits before
starting measurement. The time is given by the following formula:
wait time = initial wait time
×
A + B
where, initial wait time is the time the E5260/E5270 automatically sets and you
cannot change. The initial source wait time is not the same as the initial
measurement wait time . A and B are the command parameters of the WAT
command.
The wait time settings are effective for all modules.
Figure 1-1 Source/Measurement Wait Time
NOTE The wait time can be ignored if it is shorter than the delay time.
It is not easy to determine the best wait time. If you specify it too short, the
measurement may start before device characteristics stable. If too long, time will be
wasted.
The initial wait time may be too short for measurements of high capacitance or slow
response devices. Then set the wait time longer.
For measurements of low capacitance or fast response devices, if measurement
speed has top priority or is more important than reliability and accuracy, set the wait
time shorter.
