Section 1: Getting Started
Overview
This manual describes Keithley Instruments Model 2308 Portable Device Battery/Charger
Simulator, which is designed specifically for development and high-speed production testing of DC
battery-operated products.
Applications
Development and high speed testing of DC battery-operated products, such as:
•
Cellular handsets
•
Cellular components like RFIC power amplifiers
•
Other high-volume precision electrical components.
Performance features
Key features and benefits include:
•
The Model 2308 is a specialized power supply that has a very fast recovery to large, near
instantaneous load current transitions. Conventional power supplies do not have this
capability. The Model 2308 is designed specifically to respond to large load changes and
very short pulsed loads with small transient voltage drop and a very fast recovery time.
Typical devices that have these types of characteristic loads are mobile phones, wireless
communication modules, and other portable, battery operated devices. The Model 2308 can
maintain a near-constant output, even under quickly-changing load conditions.
•
The power supply can measure a wide range of load currents. It can resolve down to 0.1
and measure up to 5 A. It has fast measurement capability as well and can measure load
current pulses as narrow as 50
•
The Model 2308 can simulate the output of a battery. Its programmable output resistance
can simulate a battery's internal resistance so that the voltage output looks exactly like that
of a battery's output.
•
The two channels can also sink current so that one channel (the battery channel) simulates
a discharged battery, while the other channel (the charger channel) can be used to simulate
a charger.
NOTE
Warranty information
Warranty information is located at the front of this manual. Should your power supply require
warranty service, contact the Keithley Instruments representative or authorized repair facility in
your area for further information. When returning the instrument for repair, be sure to fill out and
include the service form at the back of this manual to provide the repair facility with the necessary
information.
