Low Power, Portable Devices; Power Supplies with Advanced Measurement Capability
Verifying Device Power Consumption Requires Low Current Measurement
To properly design and test low power, portable devices such as consumer products (cellular phones, tablets,
laptops), industrial products (wireless transmitters, intrinsically safe instruments), or implantable medical devices
(pacemakers, defibrillators, neurological stimulators), it's essential to verify that the goals for maximum battery
life, maximum time between re-charges, or minimum current consumption can be met. But, these tests, which
include measuring the sleep mode and standby mode currents drawn by these devices, require precise low
current measurements that are often in the range of micro-amps to hundreds of micro-amps. In addition to
good measurement techniques, sensitive instrumentation with special capabilities for measuring very small load
currents is typically necessary, adding cost and complexity to the test circuit. It would be very convenient if the
power supply used to power the device during testing could measure very low load currents, but conventional
programmable power supplies have a current measuring resolution of only 0.1mA at best and, therefore, cannot
be used to measure the ultra-low standby and sleep mode currents in today's and the next generation's low
power products.
Now there is a power supply that can make very low load current measurements and provide a cost-effective
solution. The Series 2280S Precision Measurement, Low Noise, Programmable DC Power Supplies provide the
necessary sensitivity to measure low sleep mode and standby mode currents. With 6◦ Jabse Service Manual Search 2024 ◦ Jabse Pravopis ◦ onTap.bg ◦ Other service manual resources online : Fixya ◦ eServiceinfo
