Introduction
The Keysight B2961A/62A 6.5 Digit Low Noise Power Source is a bench-top power
supply with revolutionary capabilities and functions not previously available. It can
source either voltage or current with 6.5 digits of resolution while also monitoring them,
which is essential for a variety of measurement applications.
It also has an arbitrary waveform generation function that allows it to source current/
voltage waveforms in formats such as sinusoid, square, trapezoid, ramp, triangle, and
exponential. In addition to these commonly used waveforms, user-defined arbitrary
waveforms with up to 100,000 points can be specified. These flexible output capabilities
permit more thorough evaluation of circuits/devices/samples than are possible with
other instruments such as power supplies and sources.
This demonstration guide highlights the excellent arbitrary waveform generation
functions of the B2961A/62A Power Source. The methodology involves sourcing a
sinusoidal current/voltage waveform through a 1.1 kΩ resistor and monitoring the
outputs through an oscilloscope.
Required Instrument and Accessories
All of the accessories required to perform the primary demos described in this demonstration
guide are provided in a demo kit that is included with Keysight B2961A/62A demo units. The
kit includes items such as a banana cable, a 1.1 kΩ resistor, etc., so the only additional item
needed is an oscilloscope.
However, some of the optional demos require special cables or wiring to send phase marker
outputs or to receive trigger signals. These optional items are the N1253A-100 Digital I/O
T-cable or (alternatively) the N1294A-031 GPIO - BNC Trigger Adapter and a BNC cable. An
instrument that can send the external trigger signal to the B2961A/62A will be also required
for the optional demos.
