Agilent Technologies adds two source measure units (SMUs) to its N6700 Series modular power systems.
The two source measure units include the N6781A 2-quadrant source measure unit for battery drain analysis and the N6782A 2-quadrant source measure unit for functional test.
The new SMUs offer advanced sourcing and measurement capabilities required for the testing challenges associated with battery-powered devices and their components. Agilent has also introduced new software and updates for its DC power analyser mainframe.
Referring to the battery-powered device market, Gary Whitman, Vice President and General Manager of Agilent's System Products Division says that engineers have employed advanced power management methods in order to maximise battery life.
"Until today, SMUs lacked the capabilities necessary to adequately measure the dynamic currents associated with these methods. Our new N6781A and N6782A SMUs overcome the shortcomings of today's SMUs with features designed specifically for this rapidly growing market."
The N6781A and N6782A source measure units eliminate the challenges of measuring dynamic currents with a feature called seamless measurement ranging.
The feature allows engineers to precisely measure dynamic currents without disruptions to the measurement. As the current drawn by the device under test (DUT) changes, the SMU automatically detects the change and switches to the current measurement range that will return the most precise measurement.
When combined with the SMU's built-in 18-bit digitiser, seamless measurement ranging enables unprecedented effective vertical resolution of 28-bits. This provides unrivalled productivity gains and insights into power consumption by enabling engineers to see the complete current waveform from nano-amps to amps in one pass and one picture.
N6781 2-quadrant source measure unit for battery drain analysis
- Accurately captures the power consumption of portable, battery-powered devices
- When used with the new Agilent 14585A software, the N6781A becomes an even more powerful battery drain analysis solution offering greater measurement insight
- Ideal for testing devices such as e-Book readers, MP3 players, mobile phones and pacemakers
- Seamless measurement ranging, programmable output resistance and auxiliary DVM combine to offer superior battery drain analysis
N6782A 2-quadrant source measure unit for functional test
- Modulates its output up to 100 kHz and provides 2-quadrant operation
- Perfect fit for advanced functional test of a variety of devices including DC/DC converters, power management units, power amplifiers and power management ICs
- The input stage of the DUT can be stimulated by the fast sourcing and waveform capabilities
- The output stage can be loaded down and measured with the electronic load capabilities of the N6782A
The N6781A and N6782A SMUs also offer:
- Trouble-free sourcing and measurement for changing output and measurement ranges
- 2-quadrant operation allows the SMU to perform as a voltage or current source or as a constant-voltage or constant-current electronic load
- 4 current measurement ranges to precisely capture the current levels of the DUT during different modes of operation
- Excellent transient response for keeping the voltage or current stable during high-speed load changes
- Fast modulation of DC for creating waveforms up to 100 kHz to stimulate or load down the DUT
- High-speed digitised measurements for capturing and viewing the power consumption of the DUT every five microseconds with its built-in 200 kHz digitiser
Agilent 14585A control and analysis software
The Agilent 14585A control and analysis software for the N6705 DC power analyser enhances the user experience of the N6705 mainframe by offering advanced functionality via PC control. Key features include:
- Simultaneous control and analysis of data from up to four N6705 mainframes (16 power supplies)
- Enhanced control and analysis of data using familiar PC controls and a large display
- Easy creation of complex waveforms to stimulate or load down a DUT by inputting a formula, choosing from built-in or importing waveform data
- Data logging of measurements directly to the PC
- Performs statistical analysis of power consumption
