The single-channel Model 2302 Battery
Simulator and dual-channel Model 2306 Battery/
Charger Simulator were designed specifically for
development and test applications of portable,
battery-operated products, such as cellular and
cordless telephones, mobile radios, and pagers.
These precision power supplies have ultrafast
transient response so they can have output
characteristics identical to actual batteries.
These supplies employ a unique variable output
resistance so the voltage output can emulate a
battery’s response (U.S. Patent No. 6,204,647).
They provide stable voltage outputs, even when
a device-under-test (DUT) makes the rapid tran-
sition from the standby (low current) state to the
RF transmission (high current) state. In addition,
they can monitor DUT power consumption by
meas uring both DC currents and pulse load cur-
rents. The Model 2302’s and the Model 2306’s
battery-simulator channel can be programmed
to operate like a discharged rechargeable battery, sinking current from a separate charger or from the
Model 2306’s charger- simulator channel.
Maximize Test Throughput with accurate Battery Simulation
The battery-output channels of the Models 2302 and 2306 are designed to simulate the output
response of a battery. This capability, combined with their fast transient response, makes it possible
to power the device during testing in exactly the
same way as a battery will power the device
during actual use. The output resistance of the
Model 2302’s and the Model 2306’s battery chan-
nel can be programmed (with 10m Ω resolution)
over the range from 0 Ω to 1Ω so that the out-
put resistance can be set to the same level as the
output resistance of the battery that powers the
device. See Figure 1.
Portable wireless devices make great demands
on their battery power sources. The battery must
source load currents that can jump virtually
instantaneously from a standby current level
(100–300mA) to a full-power RF transmission
current level (1–3A). In other words, the load
current on the battery can increase rapidly by
a factor of 700–1000%. As a result, the battery
voltage drops by an amount equal to the value
of the current change multiplied by the battery’s
internal resistance. The Models 2302 and 2306
power supplies enable test systems to duplicate
this voltage drop by programming their output
resistance to be equivalent to that of the battery
that will power the device. This allows wire-
less device manufacturers to test their products
under the same power conditions that they will
encounter in actual use. (See Figure 2.)
