Soaring demand for cell phones, pagers mobile radios and base-stations, is
putting pressure on test engineers to shorten production test time. This may
require selection of new test equipment that can improve throughput and
accuracy in several areas, including a wide variety of DC and low-frequency
board-level tests, and battery testing or simulation.
To test portable communication devices under realistic conditions, you may need
a power supply that can simulate a battery under various discharge states. This
requires a power supply with a variable output impedance, which closely
duplicates the voltage characteristics of a battery during energy drain. These
power supplies should also have an ultra-wide bandwidth output stage to
