These high performance models offer wireless electronic device manufacturers, designers, and repairers all the capabilities to thoroughly test the power characteristics of wireless phones and portable devices. The 66319B/D and 66321B/D high performance models are recommended for new automated test system platforms and for R&D applications. The 66309B/D and the 66311B/D are available for those customers who need to replicate existing test platforms and who do not want to re-engineer existing automated test system designs.

Performs Like a Battery
With its battery emulation feature, the Agilent 66321B/D and 66319B/D allows you to test your phones under the same power conditions as in actual use; detecting early product failures. These power supplies simulates the effects of the internal resistance in a battery, enabling them to emulate the operation of various battery types, as well as batteries in different charged states. Plus with their ability to simulate negative resistance, users can compensate for the voltage drop due to the wiring in a fixture.

Minimize Test Interruptions
Offering superior transient performance, unmatched in the market place, the Agilent Mobile Communications DC Sources with Battery Emulation dramatically reduces the transient voltage drop (< 40 µs) due to the pulse loading characteristics of mobile phones and recovers very quickly to their original voltage. The Agilent 66321B/D and 66319B/D enables you to maximize test throughput by minimizing test interruption due to triggering of low voltage phone shutdown.

Simplify Test & Analysis
With the Agilent 14565A Device Characterization Software testing, analyzing, and, troubleshooting mobile phone design and subsystem is made simple. The optional Agilent 14565A graphical user interface lets you easily control these power supplies. Plus it provides an oscilloscope-like view of the voltage or current waveform of the device under test, provides reference waveform save/recall, and oscilloscope-like waveform measurement and analysis (current or voltage measurements, triggering, markers, zoom control, and more).
