Figure 1. Comparison of the voltage outputs of a lithium-ion battery (with an internal resistance of
260m
) and the Model 2306’s battery channel (programmed with an output resistance of 260m
)
when powering a cellular telephone as it makes the transition from standby mode to transmit mode.
The single-channel Model 2302 Battery Simulator
and Model 2306 Dual Channel Battery/Charger
Simulator were designed specifically for develop-
ment and test applications for portable, battery-
operated products, such as cellular and cordless
telephones, mobile radios, and pagers. These pre-
cision 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 transition from the standby (low
current) state to the RF transmission (high cur-
rent) state. In addition, they can monitor DUT
power consumption by measuring both DC cur-
rents and pulse load currents. 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 sepa-
rate charger or 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 channel can be programmed (with
10m
resolution) over the range from 0
to 1
so that the output resistance can be set to the same
level as the output resistance of the battery that powers the device.
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 sup-
plies enable test systems to duplicate this voltage drop by programming their output resistance to be equiv-
alent to that of the battery that will power the device. This allows wireless device manufacturers to test their
products under the same power conditions that they will encounter in actual use. (See
Figure 1
.)
In response to large load changes, the Model 2302 and the battery channel of the Model 2306 have tran-
sient voltage droops of less than 100mV and transient recovery times of less than 60μs, even when the
