SHORT DESCRIPTION

Multimeter calibrator Keithley 2401 American company Keithley is a multifunctional device that combines the capabilities of a precision voltage and current source with an accurate 6.5-digit multimeter (measures voltage, current, resistance). This combination provides three main benefits: simplification and acceleration of testing tasks, cost reduction, reduction in the number of wires and space occupied by devices. The Keithley 2401 differs from other 2400-series SMUs in its reduced voltage generation/sensing level (up to 20 V).

Main characteristics:
Resolution: 6.5 bits. Basic Accuracy (DCV): 0.012%.
Voltage: 5 µV to 20 V (generation), 1 µV to 21 V (measurement).
Current: 50 pA to 1 A (generation), 10 pA to 1.05 A (measurement).
Resistance: from 100 µΩ to 200 MΩ (measurement). Output power: up to 20 W.
4-quadrant operating area (voltage/current generation or load operation).
2-wire, 4-wire and 6-wire connection scheme. Speed: up to 2,081 measurements per second.
Built-in pass/fail comparator for automatic rejection.
Ability to automatically generate a series of control points.
Free PC software and LabVIEW driver.
Interfaces: IEEE-488.2 (GPIB), RS-232, Keithley Trigger Link. Weight: 3.21 kg.
Inexpensive Low Voltage Calibrator Multimeter (SMU) up to 20V

Areas of use:
- ultra-bright LEDs (dc and pulsed)
- photovoltaic cell efficiency test (source and load)
- accurate voltage/current source and meter
- discrete semiconductor devices
- passive electronic components
- laser diodes and diode modules, LEDs, photodetectors
- connectors, switches, relays
- low voltages/resistances
- LIV (light-current-voltage)
testing - IDDQ testing
- construction of current-voltage characteristics (CVC)

 

DETAILED DESCRIPTION

Series 2400 company's multimeter calibrators Keithley specifically designed for measurement applications that require a close relationship between the test signal source and the meter. The calibrator-multimeter in English is called Source Measure Unit (source-measurement device) or abbreviated SMU. All 2400 Series SMUs contain a highly stable voltage and current source, as well as a precision multimeter. The built-in power supply has low noise, high accuracy, and the ability to control the accuracy of the output voltage and current. The built-in multimeter has low noise and high repeatability of measurement results. All these features come together in a single package, resulting in a compact, single-channel DC parametric tester. Also, the Keithley 2400 series multimeter calibrators can operate as a simple voltage, current, voltage, current, resistance meter.

 

Comparing the Capabilities of the Keithley 2400 Series Multimeter Calibrators

There are currently 8 instrument models in the 2400 series, six of which have the -C modification (automatic test of connection contacts). The series is regularly updated with new models for the optimal solution of various tasks. Model 2401 is completely similar to model 2400, only cheaper and has a reduced voltage (up to 20 V). Below is a comparison table of the capabilities of the series devices.
