SPECIALIZED POWER SUPPLIES

A GREATER MEASURE OF CONFIDENCE

Fast transient response power supplies

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 10mΩ resolution)

over the range from 0Ω 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.)
