The Keysight 66319D Mobile Communications dc Source offers a built-in advanced measurement system to accurately measure battery current drains when the device operates in different modes (such as talk mode, active mode, standby mode, and off/sleep mode). Measurements made during these modes are critical for ensuring that your devices are operating properly and that you are getting the most out of the battery.

With the battery emulation features, the Keysight 66319D Mobile Communications dc Source allows you to test your devices under the same power conditions that exist in actual use. Emulating the battery is key when characterizing battery operating life and detecting early product failures. The dc source simulates the effects of internal resistance of the battery, enabling it to emulate the operation of various battery types or batteries in different charge states. Plus, the HP 66319D can simulate negative resistance so that you can compensate for voltage drop due to wiring in a fixture.

Keysight has designed in the capability and flexibility that is required for accurately testing today's communications devices as well as your next generation designs for cell phones (formats include: 3G, cdma2000, WCDMA, CDMA, TDMA, GSM, PCS, DECT, TETRA, PHS, NADC), PDAs, Bluetooth™ enabled devices, and Wireless LAN access devices. The 66319D high performance model is recommended for new automated test system platforms and for R&D applications.
