Section 3: Brief Technical Description
AM450e is a source-measure unit (SMU).
3.1 Basic Operation
AM450e is more than the just a power supply. It is fast-response, read-back voltage and
current sources with high accuracy measurement capabilities. It is designed for circuit and
device evaluation where a DC signal must be applied to a device under test (DUT) and the
response to that signal measured. AM450e is capable of multi-quadrant operation, such as
acting as a positive DC source or as a sink (Load).
AM450e can be set up to function as a voltage source/current monitor, current source/voltage
monitor:
1. Source Current, Measure Voltage / Current
a. This configuration turns AM450e into high-impedance current source
b. The voltage developed is limited by compliance setting
c. If current is 0A, AM450e becomes a voltmeter
2. Source Voltage, Measure Current / Voltage
a. This configuration turns AM450e into low-impedance voltage source
b. Current flow is limited by compliance setting
