Introduction
This guide is designed to familiarize users of the Keithley Model 2306 Dual Channel Battery/
Charger Simulator and Model 2302 Single Channel Battery Simulator with the basic operating
features available from the instrument’s front panel and also the GPIB bus. The sequence of
operating instructions reflects the order in which the instrument would be configured for a typ-
ical application. For each operating mode, an example set of bus commands is provided. While
the SCPI command strings are generic, the exact programming syntax will depend on the test
program language.
Performance features
The battery channel, the single output channel of the Model 2302 and channel #1 on the
Model 2306, has several enhanced performance features:
1. The transient response, defined by the voltage recovery time and voltage drop when sub-
jected to a 1000% load change, is faster. For exact specifications, refer to Appendix A in
the Model 2306 Instruction Manual.
2. Three current trigger ranges for pulsed current and long integration operation as opposed
to a single range on the charger channel, channel #2 (5A). Available trigger ranges for the
5A current range: 100mA, 1A, and 5A. Available trigger ranges for the 500mA current
range (Model 2306-PJ and 2302-PJ): 10mA, 100mA, and 500mA.
3. Variable output impedance on channel #1 (0
Ω
to 1.00
Ω
in 0.01
Ω
steps). Channel #2 has
fixed output impedance.
Proper connection of the supply to the DUT
WARNING
When installing a unit into a test system, make sure the external power
sources do not apply voltage to the power supply in excess of its maximum
limits (see specifications). Failure to do so could result in personal injury or
death.
WARNING
The power cord supplied with the Model 2306 contains a separate ground
WARNING
for use with grounded outlets. When proper connections are made, instru-
ment chassis is connected to power line ground through the ground wire in
the power cord. Failure to use a grounded outlet may result in personal in-
jury or death due to electric shock.
To prevent any human contact with a live conductor, connections to the
DUT must be fully insulated and the final connections to the DUT must
only use safety-rated safety jack socket connectors that do not allow
bodily contact.
On some sensitive or easily damaged devices under test (DUTs), the instrument
power-up sequence can apply transient signals to the DUT that may affect or
damage it. When testing this type of DUT, do not make final
connections to it until the instrument has completed its power
-
up sequence
and
is in a known operating state.
