Keysight 66319D Dual Mobile Comm DC Source Battery Emulation, DVM

The Keysight 66319D Dual Mobile Comm DC Source is engineered for wireless device developers who demand precise, repeatable power testing under real-world operating conditions. With two independent outputs, the 66319D allows simultaneous powering and monitoring of mobile handsets, modules, and accessories.

A key advantage of the 66319D is its battery emulation capability, which accurately replicates the dynamic behavior of rechargeable batteries. This enables engineers to characterize power consumption, validate charging circuits, and simulate low-battery conditions without relying on physical batteries. The built-in high-performance digital voltmeter (DVM) further enhances measurement flexibility by providing accurate voltage monitoring at the device under test (DUT).

Designed for demanding R&D and production environments, the 66319D offers fast transient response, low noise, and tight load regulation, ensuring reliable results when testing devices with bursty current profiles typical of GSM, CDMA, LTE, and other wireless technologies.
