Function Details
I/V-t Sampling Measurement
Source Output Sequence and Time Origin
When the Output Sequence is SEQUENTIAL, source channels start output in order.
The order is top to bottom of the channels defined in the Channel Setup screen. The
order of bias stop is bottom to top.
When the Output Sequence is SIMULTANEOUS, sour
ce channels start output
simultaneously. And the source channels stop output at the same time.
The time origin is when the source output value is changed from Base to Source.
Sampling Completion
The sampling measurement completes when one of the following conditions is
satisfied:
• The event of the stop condition occurs. See “Stop Condition” on page 7-18.
• The measurement channels obtain the specified number (No of Sampl
es) of
measurement data.
• The total measurement time runs over the time Interval × No of Sa
mples for the
linear sampling with Interval < 2 ms.
• The Stop button is clicked.
• An emergency condition occurs on Agilent B1500A.
• Interlock terminal is opened
when a chann
el is in the high voltage output status.
Stop Condition
The stop condition is defined by using the Stop Condition fields on the
Measurement Setup screen. This function stops the measurement as shown below.
1. Compares the value of parameter set to the Name field and the value defined in
the Thr
eshold field.
2. Counts how many times the selected Event occurs.
3. When the count reaches the value defined in the No. of Events field, sampling is
stopped immediately.
For the setup parameters of the stop condition, see “I/V-t Sampling” on page 5-21.
