66319B Overview

The Keysight 66319B is a dual-output DC source designed for mobile communications. It offers two outputs for evaluating the primary battery power and the battery charger circuits, enabling users to test both phones and chargers with a single device. This not only conserves rack space (offering two outputs in a half-rack box) but also removes the need for two separate power supplies. The 66319D dc source provides all of the capabilities of the 66319B with the addition of a built-in digital voltmeter (DVM).

One of the additional key features of the 66319B is battery emulation, which allows devices to be tested under real-world power conditions. This feature is crucial for determining battery life and identifying product failures. The DC sources mimic the internal resistance of the battery, allowing them to simulate the performance of various battery types or batteries at different charge levels.

For R&D engineers, the Keysight 66319B provides the ability to characterize the current drawn from the battery and make design trade-offs that affect current drain and battery life. This is facilitated by data logging (up to 1000 hours), CCDF statistical analysis, and waveform capture when used in conjunction with the Keysight 14565B Device Characterization Software with Test Automation.

66300 Series Family of Specialized DC Power Sources

The 66300 series power supplies are specifically engineered to assist in testing mobile wireless devices. They offer DC sourcing, current sinking, and measurement functionalities to tackle the distinct difficulties of emulating batteries and battery packs, as well as gauging the current consumed by your test device.

Series Features

• Programmable output response compensation to accommodate all types of wiring configurations
• Fast DC power source to replace and simulate the battery during testing
• Fast voltage transient response ensures maximum test-system throughput by minimizing device shutdowns
• Current sinking for testing and calibrating charger circuitry
• Uses a proprietary system to automatically detect open sense wire connections
• Extensive protection features (including broken sense lead detection)
• GPIB Interface, SCPI (Standard Commands for Programmable Instruments), VXI plug&play drivers
• Dynamic measurement system enables accurate current measurement from µA to A
• 66319B/D and 66321B/D coupled with 14565B Software gives a powerful analysis tool to optimize device designs for long battery life

For scenarios where you need to substitute your device's primary battery with power during testing, single output models are suggested. On the other hand, dual output models are advised when you need to replace your device's main battery with power and simulate the power of the battery charger. In this case, one output is used to connect in lieu of the main battery (which sinks current to mimic the charging of the main battery), and the other output is used to deliver current to the battery charger's input port. Models are as follows:

Series Size 1/2 RU w x 2 RU h: RU refers to rack unit of a standard 19-inch EIA equipment rack. The width is either 1/2 or full. The height is in number of rack units which are 1.75 inches (44.4 mm) each. For example: a 3 RU h has a height of 5.25 inches (133.3 mm).
