Power of Five Instruments in One (IV Source,
IVR Measure)
The tightly coupled nature of a SourceMeter SMU
instrument provides many advantages over solutions
configured from separate instruments, such as a
precision power supply and a digital multimeter. For
example, it provides faster test times by reducing GPIB
traffic and simplifies the remote programming interface.
It also protects the device under test from damage due
to accidental overloads, thermal runaway, etc. Both
the current and voltage source are programmable with
readback to help maximize device measurement integrity.
If the readback reaches a programmed compliance limit,
then the source is clamped at the limit, providing fault
protection.
I-V Characteristics
All SourceMeter SMU instruments provide four-quadrant
operation. In the first and third quadrants they operate
as a source, delivering power to a load. In the second
and fourth quadrants they operate as a sink, dissipating
power internally. Voltage, current, and resistance can be
measured during source or sink operation.
Automation for Speed
A SourceMeter SMU instrument streamlines production
testing. It sources voltage or current while making
measurements without needing to change connections. It
is designed for reliable operation in non-stop production
environments. To provide the throughput demanded by
production applications, the SourceMeter SMU instrument
offers many built-in features that allow it to run complex
test sequences without computer control or GPIB
communications slowing things down.
Standard and Custom Sweeps
Sweep solutions greatly accelerate testing with
automation hooks. Three basic sweep waveforms are
provided that can be programmed for single-event or
continuous operation. They are ideal for I/V, I/R, V/I, and
V/R characterization.
• Linear Staircase Sweep: Moves from the start level to
the stop level in equal linear steps
• Logarithmic Staircase Sweep: Done on a log scale
with a specified number of steps per decade
• Custom Sweep: Allows construction of special
sweeps by specifying the number of measurement
points and the source level at each point
• Up to 1700 readings/second at 4½ digits to
the GPIB bus
• 5000 readings can be stored in the non-volatile
buffer memory
