Keysight's new high-current low-noise filter extends power source’s output to 500 mA



High-current ultra low noise filter for the B2961A and B2962A 6.5 Digit Low Noise Power Source

Keysight Technologies introduced a new high current ultra low noise filter for the B2961A and B2962A 6.5 Digit Low Noise Power Source that can supply up to 500 mA while maintaining 10 µVrms and 1nVrms/√Hz (at 10 kHz) noise performance. With a starting price of less than $10K, the B2961A and B2962A are the world’s only low-cost standalone power sources capable of sourcing at ultra-low noise levels. These products help researchers, electronic development engineers and electronic technicians to meet their most difficult measurement challenges during device development and evaluation.

As electronic equipment and devices become smaller, integrated and more portable, they demand greater intelligence, integration, miniaturization and lower-power consumption. Researchers, designers and developers pursuing the innovations and breakthroughs needed to develop these next-generation devices typically require basic equipment such as power supplies and sources for this work. When sensitive devices are being developed, those sources must have high precision and resolution, as well as low-noise voltage.

Keysight’s B2961A and B2962A deliver the best-in-class precision and extremely low noise floors that today’s design engineers researching and developing AD/DA converters, VCOs, sensors and transducer devices demand. Such devices often require wide current and voltage coverage with low noise. With its new ultra low noise filter, the B2961Aand B2962A can now output up to 500 mA while still maintaining an extremely low-noise floor of 10 µVrms and 1nVrms/√Hz (at 10 kHz). These capabilities make it the ideal precision source for use with other instruments such as network analyzers, signal source analyzer and nano-voltmeters.

Most signal source analyzers, even those with a built-in source, cannot simultaneously supply a low-noise voltage output at the current levels needed for many engineering applications. However, the B2961A and B2962A’s new high current ultra low noise filter meets both of these requirements.

“Accurate development and evaluation of sensitive electronic devices requires power sources with high precision, high resolution, and ultra-low noise,” said Masaki Yamamoto, general manager of Keysight’s Hachioji Semiconductor Test Division. “With the B2961A and B2962A’s enhanced high current ultra low noise filter, customers now get optimal flexibility in one power source to address even their toughest measurement challenges. Moreover, its low starting price makes it easily accessible to users working on a wide range of applications, whether analog IC companies, foundries or IDMs, just to name a few.”
