Agilent Technologies Inc. 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 revolutionary power supplies for precision low-noise voltage/current sourcing. Both units feature best-in-class 6.5 digit and 100 nV/10 fA resolutions, 10µVrms noise performance, wide bipolar operating ranges up to 210 V/3 A DC or 10.5 A pulse, more innovative sourcing functions and an intuitive graphical user interface.
These power sources offer:
- Superior 6.5 digit and 100 nV/10 fA resolutions, enabling more precise test and evaluation for higher bit ADCs or DACs that couldn't be tested with conventional voltage supplies or power sources.
- Wide bipolar voltage and current operation ranges (four-quadrant) up to 210 V/3 A DC or 10.5 A Pulse, which can cover broad applications.
- Output noise to 10 µVrms or 1 nVrms/vHz 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
- Precision arbitrary waveform generation supporting 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 output flexible voltage or current waveforms up to 210 V/3 A for advanced testing and evaluation, in addition to conventional static testing.
- 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 regulator ICs. This enables testing and evaluation under realistic conditions.
- An intuitive user interface on a 4.3-inch color LCD that includes a time-domain voltage/current waveform viewer and waveform preview.
- A built-in 4.5-digit voltage/current monitor that performs interactive testing and debugging quicker than conventional power supplies and power sources.
- 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.
