5. (Optional) Configuring the measurement speed
In the default setting, the instrument selects the appropriate measurement speed and
range automatically to get the fine accuracy. However, you can also specify these
parameters on the GUI of the B2900A Series SMU to meet a variety of the requirement
to the measurement conditions.
For example, let’s try to change the measurement speed to NORMAL to make a mea-
surement more carefully. If you select NORMAL, the aperture time is set to 1 PLC. Here,
PLC stands for power line cycle and the specified number of power line cycles is used
per a measurement.
1) Press to edit the
Measurement speed
, and then select to set the
Measurement speed
to
NORMAL
. (If you can’t see in Assist keys, press
to change the keys shown in Assist keys.)
6. (Optional) Configuring the measurement range operation
The parameters which configure the measurement range operation can be displayed in
the Range Sub-panel in the Channel 1 Single View. In the default setting, the B2900A
Series SMU performs the current measurement using a 1 μA current minimum measure
-
ment range with AUTO range operation. With AUTO range operation, the B2900A Series
SMU selects the proper range for the measurement with the specified minimum mea
-
surement range so that you don’t need to take care about it. To know how to change the
measurement range setting, try to configure to use the 10 μA current minimum mea
-
surement range with AUTO range operation.
1) Rotate and press to edit the
Current minimum measurement range
and then
select to set it to
10 μA
.
If you’d like to fix the measurement range, you can select FIXED range operation as below.
2) Rotate and press to edit the
Current measurement range operation
. Then
Select to set the
Current measurement range operation
to
FIXED.
