Introduction
The Agilent B2900A Series of
Precision Source/Measure Units are
compact and cost-effective bench-top
Source/Measure Units (SMUs) with
the capability to output and measure
both voltage and current. An SMU
combines the capabilities of a current
source, a voltage source, a current
meter and a voltage meter along
with the capability to switch easily
between these various functions
into a single instrument. The Agilent
B2900A series of SMUs provide
best-in-class performance at a lower
price than ever before. They have
broad voltage (210 V) and current (3 A
DC and 10.5 A pulsed) sourcing capability, excellent precision (minimum
10 fA/100 nV sourcing and measuring
resolution ) and high measurement
throughput. They also support an
arbitrary waveform generation function. In addition, the Agilent B2900A
series possess a superior graphical
user interface with various viewing
modes that dramatically improve test
productivity, debug and characterization. The versatile integrated source
and measurement capabilities of the
Agilent B2900 series SMUs make
them an ideal choice for testing
semiconductors, active/passive components and a variety of other devices
and materials. The B2900 series
has a broad application range that
spans from R&D and education uses
to industrial development, test and
manufacturing. Moreover, they work
equally well as either standalone
or system components. The Agilent
B2900A series consists of four models, the B2901A, B2902A, B2911A and
B2912A, differentiated through their
available features (number of digits
displayed, measurement resolution,
minimum timing interval, supported
viewing modes, etc.) and by the
number of SMU channels (one or
two) they contain. This makes it easy
to select the exact price/performance
point to meet your testing needs.

Resistance Measurement
Resistance measurement can be performed under either auto or manual test
conditions. Auto resistance measurement is performed in current source and
voltage measurement mode. The total auto resistance measurement error is
shown in the table below. The total error of a manual resistance measurement
can be calculated using the voltage and current accuracy information as shown
below.
Source I mode, manual ohm measurement (4-wire):
Total error = Vmeas/Isrc = R reading x (gain error % of V range + gain error
% of I range + offset error of I range / Isrc value %) + (offset error of V
range / Isrc value)
Source V mode, manual ohm measurement (4-wire):
Total error = Vsrc/Imeas = 1/ [1/R reading x (gain error % of I range + gain
error % of V range + offset error of V range / Vsrc value %) + (offset error of
I range / Vsrc value)]
Measurement speed = 1 PLC
Applicable for temperature: 23 °C ± 5 °C
Example of total error calculation:
I Source value = 1 mA at 1 mA range
V measure range = 2 V range
Total error (% reading + offset) = (0.02 % + 0.02 % + 200 nA/1 mA) + (350
μV/1 mA) = 0.06 % + 0.35 Ω

Introduction
The general trend in electronics is for
equipment and devices to become
smaller, integrated and more portable.
More intelligence, integration and
miniaturization are demanded along
with lower power consumption to
maximize battery life. Researchers,
designers and developers pursuing
the innovations and breakthroughs
needed to develop these nextgeneration devices typically require
basic equipment such as power
supplies and sources for this work.
Therefore, the power supplies and
sources used by these innovators
also need to possess features
advanced enough to meet the difficult
measurement challenges they often
face. The Agilent B2900A series of
precision instruments includes two
next generation of power supply/
source solutions that meet these
needs: the B2961A 6.5 Digit Low
Noise Power Source 1ch and the
B2962A 6.5 Digit Low Noise Power
Source 2ch. These products achieve
best in class precision, support wide
bipolar output ranges and have an
extremely low noise floor. They also
possess graphing capability and other
advanced features. This makes them
ideal companion products for other
instruments such as oscilloscopes,
network analyzers, spectrum analyzers, frequency counters, digital multi
meters, nano-voltmeters, etc.
The world’s only 6.5 digit source with
a bipolar range of 100 nV to 210 V
and 10 fA to 10.5 A
The Agilent B2961A/B2962A Power
Source has 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/10fA program
resolution). Unlike a typical power
supply/source, it supports 4-quardant
operation that gives you the freedom
to accurately and precisely supply any
voltage or current contained within its
ranges regardless of polarity.
Noise floor of 10 μVrms (1 nVrms /
` @10 kHz) outperforms even linear
power supplies
Low noise performance is required
for the development of noise sensitive devices such as VCOs (voltage
controlled oscillators), ADC/DAC,
new material based components, etc.
However, conventional power supplies and sources have not been able
to achieve the noise level required
for these applications. The Agilent
B2961A/B2962A supports an optional
external low noise filter that enables
ultra-low noise performance down
to 10 μVrms and 1nVrms/` (at 10
kHz), providing unparalleled low noise
performance in a low-cost bench-top
power source.
2
Innovative sourcing capabilities
enable test and evaluation not
possible with conventional power
supplies and sources
The Agilent B2961A/B2962A supports a number of innovative sourcing
capabilities for test and evaluation
that are not available on conventional
power supplies and sources. For
example, the Agilent B2961A/B2962A
has the ability to generate not only
DC signals but also pulsed, swept and
arbitrary waveforms (1 mHz to 10 kHz)
in both voltage and current. Its arbitrary waveform generation capability
supports common waveform types
such as sine, ramp, square, etc. in
addition to user-defined waveforms.
The Agilent B2961A/B2962A also
supports an advanced programmable
output resistance feature that allows
you to specify either a particular
output resistance or a specific voltage
versus current source characteristic.
This feature is ideal for emulating
a wide variety of devices (such as
batteries, photovoltaic cells, sensors,
transducers, etc.) that are otherwise
difficult to simulate.
Finally, the Agilent B2961A/B2962A
has a 4.3 inch wide LCD display and
all of its capabilities are accessible
from its front-panel graphical user
interface (GUI). The graphical display
not only simplifies user-operation, but
it also facilitates viewing measurement results. With the built-in 4.5
digit voltage and current monitoring
capability, you can check the output
voltage or current graphically by
the time domain voltage/current
waveform viewer. This permits quick
checking and debugging of measurement results without the need for
additional equipment.

Programmable Output Resistance
In its default state the Agilent B2961A/B2962A behaves like either an ideal voltage source with a negligibly small source resistance or an ideal current source
with a huge source resistance. The programmable output resistance feature
allows you to specify either a particular output resistance or a specific voltage
versus current source characteristic. This feature is ideal for emulating a wide
variety of devices (such as batteries, photovoltaic cells, sensors, transducers,
etc.) that are otherwise difficult to simulate.
Mode: Constant or V/I Emulation
Programmable resistance range:
Series resistance (Rs) at voltage source:
- (Load Resistance/2) ≤ Rs ≤ Load Resistance, for resistive load
Rs ≤ 25 Ω at 3 A range, ≤ 100 Ω at 1 A and 1.5 A ranges, ≤ 1 kΩ at 100 mA
range, or ≤ 10 kΩ at other ranges,
Rs can be limited by capacitive load.
Shunt resistance (Rsh) at current source:
Load Resistance ≤ Rsh ≤ 2 G Ω, for resistive load
Rsh ≥ 10 M Ω at 10 nA and 100 nA ranges, ≥ 1 M Ω at other ranges
Rsh can be limited by capacitive load.
Emulation mode:
Emulation mode allows you to program a non-linear resistance. You specify
the desired voltage/current characteristic using a tabular format.
Maximum number of points: 16 (piecewise linear interpolation between
points)
* Programmable Output Resistance is only available for DC output.

Program and Interface Capabilities
Programming Language
The Agilent B2961A/B2962A supports SCPI (Standard Commands for
Programmable Instruments).
Program Memory
Program memory allows you to store long strings of SCPI command lines
once into the B2961A/B2962A’s volatile memory and then recall those strings
multiple times while the program is executing using a single SCPI command. By
storing the command strings in memory, the time that would have been spent
sending those same commands over a communication bus is eliminated. For
tests that utilize lots of repeated code (such as subroutines), program memory
can dramatically reduce test times.
