Keithley SourceMeter (SMU) Instrument with GPIB & RS Interfaces, 3A – at the Test Equipment Depot. The High Voltage SourceMeter is a 60W instrument designed to source and measure voltage from ±5µV (source) and ±1µV (measure) to ±60V and current. Keithley’s Model High-Voltage SourceMeter is designed specifically for test applications that demand tightly coupled sourcing and measurement.

View Cart My Account Done on a log keithldy with a specified number of steps per decade – Custom Sweep: Unique 6-Wire Ohms Technique SourceMeter SMU instruments can make standard 4-wire, split Kelvin, and 6-wire, guarded ohms measurements and can be configured for either the constant current or constant voltage method.
The 6-wire ohms technique:. The result is a compact, single-channel, DC parametric tester.
Other capabilities of the interface include:. Three basic sweep waveforms are provided that can be programmed for single event or continuous operation.
Allows construction of special sweeps by specifying the number of measurement points and the source level at each point.
For example, it minimizes the time required for test station development, setup, and maintenance, while lowering the overall cost of system ownership.
Sweep solutions greatly accelerate testing with automation hooks. Both the current and voltage source are programmable with readback to help maximize device measurement integrity. It simplifies the test process itself by eliminating many of the complex synchronization and connection issues associated with using multiple instruments.
If the readback reaches a programmed compliance limit, then the source is clamped at the limit, providing fault protection.
The multimeter capabilities include high repeatability and low noise. For example, it provides faster test times by reducing GPIB traffic and simplifies the remote programming interface. In the first and third quadrants they operate as a source, delivering power to a load.
Providing the finest test equipment solutions since 1992
Advantages of a Tightly Integrated Instrument By linking source and measurement circuitry in a single unit, the C offers a variety of advantages over systems configured with separate source keitthley measurement instruments.
All SourceMeter SMU instruments include Keithley’s unique Trigger Link interface which provides high-speed, seamless communications with many of Keithley’s other instruments. SourceMeter SMU instruments can make standard 4-wire, split Kelvin, and 6-wire, guarded ohms measurements and can be configured for either the constant current or constant voltage method. It sources voltage or current while making measurements without needing to change connections.
Other capabilities of the interface include: 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. Done on a log scale with a specified number of steps per decade.
The 6-wire ohms technique: 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.
It is designed for reliable operation in non-stop production environments. Moves from the start level to the stop level in equal linear steps. In operation, this instrument can act as a voltage source, a current source, a voltage meter, a current meter, and an ohmmeter.
Manufacturers of components and modules for the communications, semiconductor, computer, automotive, and medical industries will find the C invaluable for a wide range of characterization and production test applications. Moves from the start level to the stop level in equal linear steps – Logarithmic Staircase Sweep: The power source characteristics include low noise, precision, and readback. In the second and fourth quadrants they operate as a sync, dissipating power internally.
By linking source and measurement circuitry in a single unit, the C offers a variety of advantages over systems configured with separate source and measurement instruments.
And its compact half-rack size conserves precious “real estate” in the test rack or bench.
