LAB1: Use Source/Measure Unit as an Ammeter
Objective
This demo illustrates the current mea-
surement function as an ammeter by
sourcing 0 V voltage and measuring the
current from the resistor biased by a
power supply using a Source/Measure
Unit.
Procedure
1. Configure the low terminal state to
FLOATING
2. Measure current using the SMU
(Channel 1) as an ammeter
3. Enable the DUT, the current soure
circuit
4. Confirm measured current
5. (Optional) Configuring the
measurement speed
6. (Optional) Configuring the
measurement range operation
Demonstration
In the default setting, the low terminal of the channels in the Keysight B2900A Series SMU is grounded
internally. However, the low terminal can be disconnected from the ground and kept floating. Configur
-
ing the low terminal state to FLOATING, which enables you to connect the low terminal to any potential
up to ±250 V, and measuring current with sourcing 0 V from the channel, which makes it possible to
use the channel as an ammeter.
1. Configure the low terminal state to FLOATING
1) If you aren’t on the top of the Function menu, press repeatedly to return to the top level.
2) Press , , and then press to open the
Output Connection
dialogue.
3) Press and select to specify the channel which the
Low terminal state
is
configured for.
