Applications
Reliability test of semiconductors and electronic components
To secure the reliability of electronic components such as semiconductor and sensors, aging tests with current applied are conducted on the devices.
Such tests require highly stable voltage sources. In some tests, the normal operating range of the devices is verified by changing the supply voltage. With its low noise, high stability and high sourcing resolution, the 6146/6156 offers high reliability in these tests.
• The 6146/6156 is used as power source to the devices or input signal.
• A digital multimeter monitor’s output voltage of the devices.
• The 6146/6156 and the digital multimeter can acquire long-time aging data using GPIB or USB.
Embedded power source or signal source in a board tester
Control boards used in home electric appliance and industrial equipment undergo functional tests at shipping and incoming inspections. The 6146/6156 can be used as embedded power source in a board tester, applying voltage to a board under test and applying voltage or current as pseudo sensor signal. As the 6146/6156 stabilizes its output values with a settling time of 10 ms or less, the time of a multi-item test can be reduced. In addition, the 6146/6156 is equipped with GPIB and USB interfaces for remote control as standard, allowing highly flexible system architect.
The 6146/6156 supplies power and applies voltage as pseudo sensor signal to the board under test. The 6146 has a minute voltage resolution of 1μV and the 6156 has that of 100nV. Thus, the 6146/6156 can be used as a substitute for sensor signal and make correct PASS/ FAIL judgment on the board.
Calibration of meters and measuring instruments
Meters or measuring instruments used in plants or instrumentation systems need to be calibrated periodically. The 6146/6156 is suitable for calibration of these meters or instruments with its high source accuracy. The calibration time can be reduced by storing voltages or currents of points to be calibrated in the memory of the 6146/6156 and reading them out by turns.
Various meters including digital multimeters can be calibrated using the 6146/6156. Zero point and full-scale calibrations are available by easy operation.
Characteristic test of strain sensors (strain gauges)
A strain gauge used in a strain or pressure sensor utilizes subtle variation in resistance. In a strain gauge test, resistance with a known load applied is measured using a Wheatstone bridge circuit. As a voltage source for the Wheatstone bridge circuit, the 6146/6156 is best suited with its high stability. The output voltage is measured by using a digital multimeter such as the 7461A.
Calibration of thermometers (6156 only)
When calibrating a thermometer that uses a thermocouple as a temperature sensor, DC voltage corresponding to thermal electromotive force of the thermocouple needs to be applied. The 6156 generates easily thermal electromotive force of thermocouples compliant with JIS. For reference junction compensation, the 6156 has a “room temperature compensation ON/OFF” function that generates thermal electromotive force to arbitrary temperature just by setting the source temperature and the room temperature.
• Set the temperature to be calibrated and the room temperature using the 6156 “thermal electromotive force output function.
• The 6156 generates voltage corresponding to the setting temperature.
• Calibrate the thermometer to the setting temperature.
Evaluation test of secondary battery control circuits
As a secondary battery such as a lithium ion battery is high-energy density, the control circuit plays an important role in monitoring the charge-discharge characteristics.
To test the operation of this control circuit, the 6146/6156 can be used as a battery simulator. The control circuit is tested correctly by changing the voltage of the battery simulator for each test item.
The 6146/6156 realizes such precise characteristic measurement with its wide measurement range, high sourcing resolution and low output noise.
