2308
Test a device’s charge control circuitry
Both channels of the Model 2308 sink up to 3A of current continuously.
Therefore, the battery channel can act like a discharged re-chargeable
battery. The charger channel can supply a charging voltage for use in
testing the operation of the DUT’s charging control circuitry. Because the
charger channel can also act as an electronic load, the battery channel can
operate the device and the charger channel can act as a load to test a bat-
tery capacity monitor or some other device function that requires a load.
For charger control circuit testing, the Model 2308’s battery channel
can sink current to simulate a discharged battery while the charger
channel simulates a charger. One instrument provides high versatility
for portable device testing.
Reduce testing errors and retesting costs
with remote sense lead monitoring
Remote sensing capabilities let the Model 2308 ensure the voltage pro-
grammed is what is actually applied to the load. As DUTs are continuously
inserted and removed from test fixtures, the instrument ensures this pro-
grammed voltage is maintained with an open sense lead detection mon-
itor—any break in a sense lead connection is detected immediately. The
open sense lead detection monitor eliminates the possibility that numerous
devices could be tested or calibrated at an incorrect voltage.
The Model 2308’s charger channel contains a built-in DVM, eliminating
the need for a separate instrument in many test systems.

Save with multiple instruments in one package –
two power supplies, a DVM, digital controls, and a
remote display
The Model 2308 saves on both instrumentation costs and rack space by
packing two independent power supply channels in one compact, 2U half-
rack enclosure, along with additional capabilities power supplies rarely
offer. For example, the built-in DC digital voltmeter can measure voltages
in the DUT circuitry from -5VDC to +30VDC. The DVM and the battery
channel voltage source can operate simultaneously. For many applications,
the Model 2308 can eliminate the need for a separate DMM.
The digital outputs the Model 2308 provides can sink up to 100mA to con-
trol relays. External relays can be powered either by the internal 5V source
or an external source with a maximum voltage of 24V. For applications that
require only a few digital control lines, the Model 2308 eliminates the need
for an additional control module.
Need to reduce your test
system size or want more sys-
tem organization flexibility?
Then mount the Model 2308
in the back of a test rack or
near the test fixture—mount-
ing the instrument in the
test rack is unnecessary. The
Model 2308’s tiny (4.6 in. ×
2.7 in.) remote display can be
mounted anywhere for easy
viewing of the outputs of both
channels. If the Model 2308 is
inaccessible, you can control it
from the remote display because it has all the front panel pushbuttons that
are on the instrument itself.
Reduce test system problems with low impedance cable
Keithley’s SC-182 Low Inductance Coaxial Cable is designed to minimize
the impedance and reduce the susceptibility to external EMI in your DC
source-DUT circuit. This cable’s characteristic impedance is nominally 15W
with a low 42nH/ft of inductance and a low 182pF/ft of capacitance. In con-
trast, a typical coaxial cable has 50W or 75W characteristic impedance and
twisted-wire pairs have at least 80W of characteristic impedance.
