Model 2303/2304A Block Diagram showing
DC DVM measurement capability
The Models 2303/2304A perform a continu-
ous integration to make peak, average, and
baseline measurements on complex load
current waveforms. Integra tion times can be
programmed with 33.3µs resolution.

Fast Measurements for
Power Consumption Analysis
As manufacturers of portable devices strive
to extend battery life and the length of time
between recharges, power consumption has
become an im por tant performance indicator.
Therefore, in production testing, accurate peak
power and average power measurements are criti-
cal. These mea sure ments are complicated by the
fact that wireless tele com munication devices draw
full load current in short pulses. The Mo dels
2303/2304A’s pulse readback mea sure ment mode
makes it possible to capture peak and average
values on pulses as short as 60µs. This allows the
power supply to power a device-under-test and
determine its current con sump tion to qualify the
device for its specified power consumption.
In addition to making measurements on short
pulses, the 2303/2304A power supplies can
measure a current pulse peak or a current pulse
train that is as long as 833ms. For random pulse
trains that have periods longer than 833ms, the
power supplies have a special long integration
mode that can make an average current meas-
urement on up to 60s of data. To capture low
current pulses from very low power devices, the
Model 2303-PJ provides pulse measurement on
both the 5A and 500mA ranges.
Accurate Low Current Measurements
The Models 2303/2304A are well-suited for
making fast, accurate measurements of sleep and
standby mode currents because they are based on
Keithley’s ex per tise in low current measurement
tech nol o gies. With 100nA resolution, the power
supplies offer the precision needed to monitor
the low sleep mode currents in today’s products
and in future products. They can also measure
these low currents with 0.2% basic accuracy.
High Current Sinking Capacity
Keithley’s power supplies can act as an electron-
ic load and sink as much as 3A (Model 2304A)

and 2A (Model 2303), so they can simu late a
discharged rechargeable battery. Therefore,
they can be used to verify the performance of a
portable device’s charger. The power supplies’
cur rent dissipation capacity allows them to test
even high-current fast chargers.
Independent Digital Voltmeter Inputs
While many programmable power supplies offer
output readback ca pa bilities, Keithley’s power
supplies are the only instruments available that
also of fer a set of DVM inputs. These inputs allow
the Model 2304A to measure signals from 0 to
+20V (0 to +15V for the Model 2303) anywhere
in the test system with the same rated accuracy
as the voltage readback. The DVM and the power
source can operate simul taneously. For many
applications, the power supplies’ built-in DVM
elimi nat es the expense and space that a separate
voltage measurement in stru ment would require.
Remote Display Option
If the Model 2303 or 2304A must be mounted
in a location in which the display is not readily
visible, an optional Model 2304-DISP Display
Module can be mounted at a more convenient
point, then plugged into the power supply unit.
The display module also includes all in stru ment
controls, so that the power supply can be oper-
ated remotely from the more ac ces sible location.
