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 components like RFIC power amplifiers, and other
high volume precision electrical components
that require a DC voltage supply. LikeKeithley’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 output 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
allowindependent control of the instrument’s
output channels. These trigger inputs speed and
simplify control of the output channels by eliminating the time lags associated with GPIB data
communications. The Model 2306-VS combines
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 GPIBinteraction.
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 initiate 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-insequences.
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 component specifications.
This precision power supply has ultra-fast transient response toduplicate 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 instrument is used with long test leads. The Model 2306-VS also employs a unique variable output resistance so that the voltage output can emulate a battery’s trueresponse (U.S. Patent No. 6,204,647). By
providing stable output voltage, a device-undertest (DUT) can transition from standby power
(low current) to RF transmission (high current)
