For applications requiring ultra-low
noise performance, the Agilent
B2961A/B2962Asupportstwoexter-
nal filter options. This provides you
with the flexibility to select the noise
filter price/performance point that
best meets your needs. The low noise
filter (LNF) provides the same level of
RMS noise as linear regulator-based
power supplies and sources, while
the ultra low noise filter (ULNF)
reduces noise to an impressive
10 µVrms.
Many power supplies and sources
only possess a numerical display
or a very basic dot matrix display,
which are only effective at showing
DC values. In contrast, the Agilent
B2961A/B2962Ahasaneasy-to-use
front panel GUI and a wide 4.3” color
LCD. These make it easy to set up
sourcing parameters and to display
complex current and voltage wave-
forms. For added convenience, the
AgilentB2961A/B2962Aprovides
multiple viewing modes: single view,
dualview(B2962Aonly)andgraph
view. These capabilities not only
increase test and evaluation efficiency,
but they also make the instrument
easy to use without the need to strug-
gle through paper manuals.

High Performance DC Power Supplies speed and accuracy for test optimization
Key features and benefits:
World’s only source with 6.5 digit
resolution and a wide bipolar range
of 100 nV - 210 V/10 fA - 10.5 A
TheAgilentB2961A/B2962APower
Sources have broad voltage (up to
±210 V) and current (up to ±3 A DC
and ±10.5 A pulsed) sourcing ranges
and excellent 6.5 digit resolution
(minimum 100 nV/10 fA program
resolution). This enables you to
source voltage from 100 nV to 210 V
and current from 10 fA to 3 A DC/
10.5 A pulsed in a single box.
Unlike a typical power supply/
source, they support 4-quardant
operation that gives you the freedom
to accurately and precisely supply
any voltage or current contained
within their ranges and power limit
(31.8 W) regardless of polarity.
Best-in-class noise floor of 10 µVrms
(1 nVrms/√Hz @10 kHz) outperforms that
of even linear power supplies
Low noise performance is required
for the development of noise sensi-
tive applications such as VCOs
(voltage controlled oscillators),
ADC/DAC, new material evaluation,
etc. However, conventional power
supplies and sources have not been
able to achieve the noise levels
to meet these needs. The Agilent
B2961A/B2962Asupportsanoptional
external
filter that enables ultra-low
noise output down to 10 µVrms and
1 nVrms/√Hz (at 10 kHz), which has
never before been possible on a
low-cost bench-top source.
Quick front-panel debug and verification
TheAgilentB2961A/B2962Ahavea
4.3 inch wide LCD display, and all of
their capabilities are accessible from
the front-panel graphical user inter-
face (GUI). The graphical display not
only simplifies user-operation, but it
also facilitates viewing measurement
results. In addition to their built-in
4.5 digit voltage and current monitoring
capability,theAgilentB2961A/B2962A
can display results in numerical or
graphical (V-t/I-t) formats on their
screen. This permits quick checking
and debugging of measurement
results without the need for addi-
tional equipment.
Flexible arbitrary waveform generation
capabilities provide more flexibility
than simple DC
In addition to DC output, the Agilent
B2961A/B2962Ahastheabilityto
generate pulsed, swept and arbitrary
waveforms in both voltage and current
anywhere within its wide output
range. Its arbitrary waveform gen-
eration capability supports common
waveform types (sine, ramp, square,
etc.) in addition to user-defined
waveforms. This provides a great
deal of versatility and allows the
B2961A/B2962Atobeusedin
many complex applications.
The ability to emulate many types
of voltage and current characteristics
aids device evaluation
The programmable output resistance
feature allows you to specify either
an output resistance (positive or
negative) or a specific voltage vs.
current source characteristic. This
feature is ideal for emulating a wide
variety of devices (such as batteries,
photovoltaic cells, sensors, transduc-
ers, etc.) that are otherwise difficult
to simulate.
