Introduction
Overview The PPH-1503 is a portable high-speed
programmable DC power supply with flexible
operating configurations. In addition to the basic
power supply functionality, it is also able to
measure pulse current and the average current
over long periods of time.
The PPH-1503 is designed for testing the power
consumption of battery powered wireless
communication devices (e.g. cell phones). Such
devices often have large load variations within a
short time span. The high precision power supply
has excellent voltage stability during pulsed loads
and is capable of simultaneously measuring the
pulse current, even for very short pulses. In
addition, the power supply is able to sink current,
allowing it to simulate the characterics of a
discharged rechargeable battery for testing
chargers and charge control circuits.
