(U.S. only)

these external trigger inputs with built-in test sequencing to create an extremely fast voltage supply

and measurement instrument that minimizes the need for computer and GPIB interaction.

External Triggering Allows High Speed Control of Output Channels

When triggered, the output channels can be instructed to operate at pre-defined voltages or to initi-

ate current, voltage, or pulse current measurements. The availability of two inputs makes it possible

to program each channel to act independently or, if the test developer prefers, to act in parallel. For

example, Channel #1 can be programmed to operate at user-specified voltage levels while Channel

#2 is triggered to take measurements. Measurements are stored in a reading buffer and can be

downloaded to a PC controller after the test routine is complete, minimizing GPIB command and

data transfer delays. Trigger outputs indicate event completion, allowing users to minimize step

delays between trigger-in sequences.

External triggering also allows the Model 2306-VS to exercise tight control over signal capture timing

for greater measurement and load condition coordination. As a result, manufacturers can achieve

greater confidence in their own compliance testing and can offer their customers more accurate com-

ponent specifications.

This precision power supply has ultra-fast transient response to duplicate the output characteristics

of actual batteries. In response to large load changes, voltage droops on the Model 2306-VS’s battery

channel are less than 100mV and transient recovery times are less than 60µs, even when the instru-

ment is used with long test leads. The Model 2306-VS also employs a unique variable output resist-

ance so that the voltage output can emulate a battery’s true response (U.S. Patent No. 6,204,647). By

providing stable output voltage, a device-under-

test (DUT) can transition from standby power

(low current) to RF transmission (high current)

seamlessly without nuisance tripping.

Built-in Test Sequencing

Maximizes Throughput

The Model 2306-VS’s built-in test sequencing

capabilities allow setting up and executing

up to 20 individual voltage and measurement

sequences. By minimizing the need to transfer

instrument commands or data over the GPIB

Dual-Channel Battery/Charger

Simulator with External Triggering

G R E A T E R

M E A S U R E

The dual-channel Model 2306-VS Battery/

Charger Simulator with External Triggering is

designed specifically for development and high

speed production testing of DC battery-operated

products, such as cellular handsets, cellular com-

ponents like RFIC power amplifiers, and other

high volume precision electrical components

that require a DC voltage supply. Like Keithley’s

original single- channel Model 2302 Battery

Simulator and dual-channel Model 2306 Battery/

Charger Simulator, this precision power supply

has ultra-fast transient response to provide out-

put characteristics identical to actual batteries.

However, in addition to the capabilities offered

by these models, the Model 2306-VS (voltage

step) provides two external trigger inputs, which

allow independent control of the instrument’s

output channels. These trigger inputs speed and

simplify control of the output channels by elimi-

nating the time lags associated with GPIB data

communications. The Model 2306-VS combines

... The Model 2306-VS also eliminates the large stabilizing capacitors needed at the DUT to compensate for the large voltage droop that occurs when testing with conventional power supplies. By varying the output resist ance, which can be done while the output is turned on, test engineers can simulate the operation of different battery types as well as batteries nearing the end of their useful lives ...
