November 18, 2012. Agilent Technologies has introduced two new low-noise power sources. Members of the Agilent B2900A precision instrument family, the one-channel B2961A and the two-channel B2962A are power supplies for precision low-noise voltage/current sourcing.
Both units feature 6.5-digit and 100-nV/10-fA resolutions, 10-μV rms noise performance, wide bipolar operating ranges up to 210 V/3 A DC or 10.5 A pulse, and a graphical user interface incorporating 4.3-inch color LCD that includes a time-domain voltage/current waveform viewer and waveform preview.
Agilent’s new power sources are suitable for use where precision, low noise, and more sourcing capabilities are required. They incorporate performance and innovative sourcing capabilities beyond just a DC power source for every research and industry area.
The sources offer utput noise to 10 μVrms or 1 nVrms/√Hz at 10 kHz using an optional ultra-low-noise filter. This enables critical testing of noise-sensitive devices or samples such as VCOs, crystal oscillators, ADCs, DACs, sensor/transducer devices, and analog/RF ICs.
Precision arbitrary waveform generation capability supports six predefined common waveforms and a user-defined waveform at a frequency range from 10 mHz to 10 kHz. Unlike conventional power supplies and power sources, these power supplies enable engineers to output flexible voltage or current waveforms up to 210 V/3 A for advanced testing and evaluation, in addition to conventional static testing.
The sources also offer programmable output resistance with emulation of DC voltage/current output characteristics. By programming DC characteristics, the power supply works as a virtual device in place of an actual device such as an energy-generating device, driver ICs, or regulator ICs. A built-in 4.5-digit voltage/current monitor supports interactive testing and debugging.
The B2961A 6.5-digit low-noise power source (31.8 W, 210 V, 3 A, one-channel) starts at $5,784. The B2962A 6.5-digit low-noise power source (31.8 W, 210 V, 3 A, two channels) starts at $8,413.
