Agilent B2901/02/11/12A Precision Source/Measure Unit
How to make a list sweep measurement
This material shows how to perform a list sweep measurement through an example of the Photovoltaic Cell IV
measurement. Figure 1 illustrates the connection and condition supposed in the example of measuring Photovoltaic Cell
using the B2901/02/11/12A.

Figure 2 shows the timing chart for the list sweep measurement with the front panel operation. In this case, the specified
source value is sourced immediately after turning on
. Then, when you press
, the instrument will
make a list sweep measurement. If it is necessary, you can specify any measurement trigger delay time which is the wait
time after sourcing each source value and before making a measurement. The measurement time consists of
Measurement Speed and some overhead time. Measurement Speed is the parameter specified by the user. Overhead
time includes the time to change the measurement range, etc.
