03 | Keysight | Using Source/Measure Unit as an Ammeter – Demo Guide
Figure 1. Connection diagram and basic condition
Concept
Figure 1 illustrates the connection diagram used in the demo to use the Keysight B2900A
Series SMU as an ammeter. Since the current polarity of the SMU is opposite to an ammeter,
the Low Force terminal of the channel has to be connected to the current output port of the
device under test (DUT).
In this demo, a 1.1 kΩ resistor combined with a power supply is used as a DUT, a current source
circuit. The channel 2 of the B2902A/12A is used as a power supply. However, you can also use
your own power supply for it.
Setup
1. Connect the
yellow banana plug
of the 11059A to the
Ch 1 Low Force
Terminal.
2. Connect the
red banana plug
of the 11059A to the
Ch1 High Force
Terminal.
3. Clip the
end of the 1.1 kΩ
resistor with the
black gold-plated tweezers
of the 11059A.
4. Connect the
black banana cable
of the U8201A to the
Ch2 Low Force
Terminal.
5. Connect the
red banana cable
of the U8201A to the
Ch2 High Force
Terminal.
6. Clip the other
end of the 1.1 kΩ
resistor with the
red alligator clip
of the U8201A
7. Connect the
red gold-plated tweezers
of the 11059A to the
black alligator clip
of the U8201A.
