Measure Load Currents for Power Consumption Verification or Analysis
The Model 2306-VS is based on Keithley’s expertise in low current measurement technologies, so it
is well-suited for making accurate measurements of load currents. With 100nA resolution and 0.2%
basic accuracy, it provides the precision needed to monitor the low sleep mode currents of today’s
battery-operated products.
The Model 2306-VS can monitor DUT power consumption by measuring both DC currents and pulse
load currents. The instrument’s battery-simulator channel can be programmed to operate like a dis-
charged rechargeable battery, sinking up to 3A from the charger-simulator channel.
Maximize Test Throughput with Accurate Battery Simulation
The Model 2306-VS’s battery-output channel is designed to simulate the output response of a battery.
This capability, combined with its fast transient response, makes it possible to power the device
during testing in exactly the same way as a battery powers the device during actual use. The output
resistance of the battery channel can be programmed (with 10mW resolution) over the range from
0W to 1W 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 Model 2306-VS enables 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
wireless device manufacturers to test their products under the same power conditions that they will
encounter in actual use.
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.
The Model 2306-VS ensures maximum production throughput when testing portable devices by
minimizing false failures, minimizing the number of test setups by performing multiple tests with
the same power supply, and minimizing test fixture complexity by eliminating the need for voltage-
stabilizing capacitors.

Open Sense Lead Detection
The Model 2306-VS has an automatic open-sense
lead detection capability, which indicates if there is
a broken remote sense lead or an open connection
from a remote sense lead to the test fixture. To ensure
that the output voltage does not change from the pro-
grammed level, which could cause production devices
to be improperly calibrated, the user can set high and
low limits around the desired voltage level.
Independent Digital Voltmeter Inputs
Many programmable power supplies offer output read-
back capabilities, but the Model 2306-VS also offers
two digital voltmeter (DVM) inputs. These inputs can
be used to measure signals from –5V to +30V DC any-
where in the test system with the same rated accuracy
as the voltage readback. For many applications, this
built-in DVM eliminates the expense and space other-
wise required to add a separate voltage measurement
instrument to the system.
