Programmable Power Modules are a combined power supply and recording scope. They are designed mainly to test and characterise storage devices.
Each module has dual power outputs (5v/12v or 3.3v/12v). The output can be set to any level and slewed rapidly to create voltage patterns.
A linear regulator allows the output to range from 0v to 20% above the nominal rail value.
Voltage and Current is simultaneously measured on both channels, giving a very accurate power reading. Measurements are taken at 250KHz with a range of averaging levels.
On board memory and a variety of triggering options allow power traces to be easily captured and downloaded for analysis.
