Function Details

I/V-t Sampling Measurement

1. When the Output Sequence is SEQUENTIAL, source channels start the Source

value output in order, and the last source channel starts the Base value output

(Starts sampling). See “Source Output Sequence and Time Origin” on page

7-18.

When the Output Sequence is SIMULTANEOUS, source chann

els start the Base

value output simultaneously (Starts sampling).

Base value is available for all output channels for the SIMULTANEOUS mode

and the las

t source channel for the SEQUENTIAL mode.

2. Base Hold Time later, th

e source channels change the output to the Source value.

The channels keep the value until the end of the sampling measurement.

3. Another Hold Time

later, the measurement channel starts measurement for the

first sampling point. If multiple channels are used, the channels perform

measurement in order. See “Multiple Measurement Channels” on page 7-61.

4. After that, the following operation is repeated with the specified time Interval.

This op

eration is repeated until the number of measurement result data reaches

the specified No

of Samples of measurement data.

• Measurement channels start measurement if they

are ready to measure.

• Measurement channels keep the condition if they

are busy.

For the log sampling, the B1500A holds only the data that can be plotted on the

log scale i

n the same distance as close as possible. Only the held data is counted

in the number of measurement result data.

For the linear sampling with Interval

< 2 ms, if the total measurement time runs

over the specified time Interval × No of Samples, the sampli

ng measurement will

be stopped even if the number of measurement result data is less than the

specified No of Samples.

5. The source channels stop the output, and the I/V-t sampling measurement is

completed.

the bias hold function is enabled, the source channe

ls force the Base or Source

value.

NOTE Time data and index

For the log sampling, the recorded data will be only the data that can be plotted on

the log scale in the same distance as close as possible. The index of the first data is

1. And the index of the following data will increase by 1. For the linear sampling,

see “Time Data and Index” on page 7-17.
