SMU Measurement Time
Wait Time
Wait time is the time after starting source output until changing the source output
value or until starting measurement. You can set the source wait time and the
measurement wait time individually.
The source wait time is the time the source channel always waits after it starts output
until it changes the output value. The measurement wait time is the time the
measurement channel always waits after the source channel starts output until the
measurement channel starts measurement. Refer to
Figure 4-33. The wait time is
given by the following formula:
wait time = N reference
where reference is the wait time the B1500 automatically sets according to the
present settings; this wait time cannot change. Available N values are 0 to 10, 0.1
step. Initial value is 1.
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. 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. The initial wait time may be too short for
measurements of high capacitance or slow response devices. Then set the wait time
longer.
Figure 4-33 Source/Measurement Wait Time
NOTE In the GPIB remote mode, if the delay time is longer than the wait time, the wait
time can be ignored.
The EasyEXPERT does not support the step delay time.
