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 next-generation
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
Inc. 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
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.

Programmable Output Resistance
In its default state the Keysight 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:
Rs can be limited by capacitive load.
Shunt resistance (Rsh) at current source:
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.
External Low Noise Filter Supplemental Characteristics
The Keysight B2961A/B2962A supports dedicated external low-noise filters; they

Operation and Functions
18 | Keysight | B2961/62A 6.5 Digit Low Noise Power Source - Data Sheet
Single view
Single view provides basic and advanced settings and display capabilities
for a selected channel from the front panel of the instrument. The DC, pulse
and integrated arbitrary waveform generation capabilities do not require any
additional controller or software. The GUI has a feature that allows you to preview
an arbitrary waveform before application. It also displays the measured voltage
Dual view
Dual view allows you to view both channels simultaneously and provides basic
setting and display capabilities. It also displays the measured voltage and current
for the B2962A
Graph view
Graph View displays measurement results in the time-domain (V-t or I-t curves)
for up to 2 channels. This is useful for quick checking and debug of the output
waveform(s).
Easy-to-use Key Operations
– Numeric/alpha keys, assist key and rotary knob for easy operation.
– Numeric/alpha keys enable direct input of alphanumeric values.
– Assist key guides operation on the front panel.
Easy Access to Source/Measurement Capabilities
Settings:
– V/I source mode
– Source value
– Limit (compliance) value
– Sweep parameters
– Pulse parameters
– Parameters for built-in waveform
– Measure speed
– Range setting
– Trigger setting
Displays:
– Numeric display in 6.5 digits for sourcing
–
– V-t/I-t curve in Graph View
Advanced Capabilities:
– Trace memory for accumulating measurement (or math) result and
collecting their statistics
File Operations (USB memory):
– Save
–
– Measurement/Math result
– Trace data
– Graph screen dump
– Load

Program and Interface Capabilities
Programming Language
The Keysight 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.
Maximum number of characters in program name:
32, consisting of alphabetic characters, numbers, hyphens and underscores.
Maximum memory size: 100 KB (2500 lines typical)
LXI
LXI Core Conformant. The Keysight B2961A/B2962A follows specified LAN
protocols and adheres to LXI requirements such as a built-in Web control server
and IVI-COM driver.
Ethernet: 10/100Base-T
USB2.0:
GPIB:
USB file system
USB 2.0 high-speed mass storage (MSC) class device (Front x 1)
Digital I/O interface
Connector: 25-pin female D.
Absolute maximum input voltage: 5.25 V
Absolute minimum input voltage: - 0.25 V
Logic low maximum input voltage: 0.8 V
Logic high minimum input voltage: 2.0 V
5 V power supply pin:
Limited to 600 mA, solid state fuse protected.
Safety interlock pin:
One active high pin and one active low pin. Activation of both pin enables output
Maximum Number of Simultaneously Triggered Units (using Digital I/O) 1: 8
