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 1 nVrms/√Hz (at 10 kHz) noise performance. With a starting price of less than $10,000 USD, 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 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. This new high current ultra low noise filter’s capabilities make it an 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.
