Ultra-low-noise filter for power sources

15 June 2016 Power Electronics / Power Management

Keysight Technologies introduced a new high-current, ultra-low-noise filter for the B2961A and B2962A 6,5 digit low-noise power sources that can supply up to 500 mA while maintaining 10 μVrms and 1 nVrms/√Hz (at 10 kHz) noise performance.

As electronic equipment and devices become smaller, integrated and more portable, they demand greater intelligence, integration, miniaturisation 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 precision and extremely low noise floors required by 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

1 nVrms//√Hz (at 10 kHz). These capabilities make it an ideal precision source for use with other instruments such as network analysers, signal source analysers and nano-voltmeters.

Most signal source analysers, 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.
