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 6-9. The wait time is
given by the following formula:
wait time = N × reference
where reference is the wait time the Keysight E5260/E5270 automatically sets
according to the present settings; this wait time cannot changed. 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.

NOTE In the local mode, you cannot set the hold time, delay time, and step delay time.
They are automatically set to 0 s.
In the remote mode, if the delay time is longer than the wait time, the wait time can
be ignored.
