Whether you are measuring temperature,
AC or DC voltage, resistance, frequency,
current, or custom measurements, the
34980A offers the functionality you need
in a single box. Switch in different measurements with high-performance signal switching up to 300V with no external signal
conditioning required. Choose between
different switch types and topologies with
frequency ranges from DC to 26.5 GHz. The
34980A offers high-density multiplexers for
scanning multiple channels, matrices for
connecting multiple points at one time, and
general purpose switches for simple control
and high power needs.
Use the 34980A to route individual signals
or monitor multiple signals over a specified
period of time—monitor a single channel or
multiple channels, set alarms, and identify
irregularities.
The 34980A offers flexible choices for
system control. You can control external
devices such as microwave switches,
attenuators, solenoids, and power relays. Or
use the digital inputs to sense limit-switch
and digital-bus status.
Optimized for test systems
The 34980A has the performance you need
for medium- to high-density switching/
measurement applications such as design
verification, functional test and data acquisition. Your signals are switched to the right
measurement device without compromising
signal integrity. Switch your signals to the
optional internal DMM and achieve optimal
throughput on switch closure time. Or, if
you prefer, you can easily connect to external instruments such as DMMs, scopes,
power supplies, and more. What’s more,
with the built-in Ethernet interface, you can
control the 34980A and collect data from
anywhere on the network. For a complete
modular solution, use the 34980A together
with PXI modular products when more
capability is required.
The rugged instrument comes with
a variety of system-ready features:
• Web browser interface shows
settings at a glance and provides remote
access and control
• Self-guiding front panel to configure,
troubleshoot or view data
• Low EMI and efficient system
cooling
• Heavy-duty cabling and connection
options
• Flexible rack mounting options
• Relay counters help predict endof-life
• In-rack calibration for reduced maintenance time
• DMM measurement accuracies include
the switch for simple
calculations
Make system connections easily
and quickly with simple, reliable
connection options:
• Built-in Ethernet, USB 2.0,
and GPIB connectivity
• Low-cost, standard 50- or 78-pin Dsub
connectors and cables
• Detachable terminal blocks with strain
relief
• Mass interconnect solutions
In addition, the 34980A comes with Agilent
IO Libraries Suite. Quickly establish an
error-free connection between your PC
and instruments—regardless of vendor.
The IO Libraries provide robust instrument
control and work with the software development environment you choose.
Easier signal routing with four
2-wire internal analog buses. You can route
your measurements directly to the internal DMM, or you can connect to external
instruments through the analog bus connector on the rear of the mainframe. And
since you have four 2-wire buses, you can
dedicate one bus for use with the internal
DMM and use the other three buses for
module extensions or additional signal routing between modules, reducing your wiring
needs.
You can define up to 500 switch sequences
to control complex signal routing and
the order of switch closures. Assign a
sequence, give it a name and then execute
it with the name you created.
Switch sequences are downloaded and
stored in the instrument for ease of programming and increased throughput.
• Built-in thermocouple reference
for temperature measurements (34921T)
Modules provide flexible system
stimulus and control
• Time-stamped readings
System control—with analog outputs,
open-collector digital outputs, clock generation, and isolated Form-C relays for controlling external devices. Additionally, with the
microwave switch/attenuator driver, highfrequency switches and attenuators can be
efficiently controlled external to the 34980A
mainframe.
• Add more formulas with BenchLink Data
Logger Software
The integrated DMM is mounted inside
the mainframe and does not consume
any of the eight user-available slots. You
can access the DMM through any switch
module that connects to the analog bus,
or directly from the analog bus connector
on the rear of the mainframe. The internal
DMM gives you the flexibility to measure
11 types of inputs:
• Temperature with thermocouples, RTDs,
or thermistors (with 34921A)
• DC and AC voltage
• 2- and 4-wire resistance
External trigger capabilities make it easy for
you to time and synchronize measurements
and other events. This can help you determine when to begin or end an acquisition.
Measurements you can trust
Get proven performance from Agilent
instruments, with the resolution, repeatability, speed, and accuracy you’ve come
to expect.
The 34980A offers built-in signal conditioning and modular flexibility. When you use it
with the internal DMM, you can configure
each channel independently for the measurements you choose. It includes a variety
of features that give you confidence in your
measurements:
• 6½ digits of resolution with .004%
of accuracy with DC voltage
measurements
• Alarms per channel—high limit,
low limit, or both
• Math functions—use Mx+B for
custom linear conversions and
converting raw inputs
• Frequency and period
Analog sources—output either voltage or
current. You can configure the 4-channel
isolated D/A converter as a point-to-point
arbitrary waveform generator that lets you
define up to 500,000 points per waveform.
Digital patterns—send or receive digital
data from your device under test. With onboard memory you can output communication protocols and bit streams or monitor
digital input patterns and interrupt when a
user-defined pattern is detected.
• DC and AC current
You can control the DMM directly, or
configure it to work in conjunction with
the switches. Each switch channel can be
configured independently for measurement
functions, scale factors and alarm limits.
Advanced measurement features such as
offset compensation, variable integration
time, and delay are also selectable on a
per-channel basis.
The DMM inputs are shielded and optically isolated from the 34980A’s earthreferenced circuitry and computer interface,
and as a result, you get up to 300 V of input
isolation. This is important for reducing
ground-loops and common-mode voltage
errors associated with long wiring runs and
floating sources.
Simple DMM calibration is
accomplished with just the analog bus connection on the rear panel of the mainframe.
You don’t need to remove the mainframe
from the rack or dedicate a channel for
calibration.

Multiple multiplexers can connect
to the built-in analog buses, allowing you
to scan up to 560 2-wire channels or 640
1-wire channels in a single mainframe. The
34921A also offers 4 channels for directly
measuring current. Or if you need more current channels, shunts can be added to the
terminal block for easy current measurements.
The multiplexer modules feature breakbefore-make connections to ensure that no
two signals are connected to each other
during a scan. Or, if you prefer, you can
control switching manually to create your
own switch configuration. All the multiplexer switches have a relay counter to help
predict when relays need to be replaced.

Each cross-point in the matrix switch has
two wires—a high and a low for the measurement. Or, if you prefer, the 34933A and
34934A can be configured as a single-wire
matrix, increasing the number of channels.
The 34933A also has in-rush resistors on
each column for added protection.
The 34934A also has in-rush protection
resistors, but also has an automatic bypass
switch for flexibility in making low-level
measurements. Row disconnect switches
also reduce the capacitance loading when
combining modules to create larger matricies.
Multiple matrix modules can be combined
through the analog bus or the row expansion kit (34934A only) to create a larger
matrix. The matrix can then be connected
to the internal DMM for easy measurements.

Combine your matrix with a multiplexer
switch to achieve the desired switching
topology and get a lower-cost solution with
better specifications. All the matrix switches
include a relay counter to help predict
when relays need to be replaced. Use
the sequencing feature to easily change
between different cross-point setups.
Note: The 34933A and 34934A have 100

34980A general-purpose
switch modules
The 34980A general-purpose switches can
be used to route signals or to control other
system devices. These switches are ideal
for device actuation and switching loads or
power supplies.
Choose from the following features:
• Form C channels up to 1 A, 50 W
• Form A channels up to 5 A, 150 W
• Armature latching relays
• Temperature sensor to detect
overheating conditions
• Connections via standard 50 or 78-pin
Dsub cables or detachable terminal block
The 34937A is the most versatile generalpurpose switch with 28 Form C channels that
can switch up to 1 A of current. In addition,
this module has four Form A channels that
can switch up to 5 A of current. For power
switching applications, the 34938A has 20
5-amp channels in a Form A topology. Each
Form A general-purpose switch can handle
up to 150 W, enough for many power line-
switching applications. For high density
applications the 34939A offers 64 Form A
channels for switching up to 1A and carry
currents up to 2A.
The general purpose switches contain
latching armature relays where multiple
channels can be closed at the same time.
Additionally, for switching reactive loads,
the optional terminal blocks have pads for
snubbing circuits.
The built-in relay counter helps predict
when relays need to be replaced.

34980A RF and microwave
switch modules
The 34980A offers a variety of RF and
microwave switch modules—RF multiplexers, SPDT switching from DC to 26.5 GHz,
or a switch/ attenuator driver module that
allows you to control switches or attenuators external to the 34980A mainframe.
34941A/42A—from DC to 3 GHz
The RF switch modules can be used to
switch signals from DC to 3 GHz and above.
This can be useful for switching signals
between oscilloscopes, spectrum analyzers,
network analyzers, and other RF test
equipment.
Choose from the following features:
• 50- or 75-ohm Quad 4-channel
multiplexers
The 34941A and 34942A are configured
as four independent 1x4 RF multiplexers
on a single module. Multiple banks can
be connected together to create a larger
multiplexer. To prevent ground loops, individual multiplexers are isolated from each
other and from the mainframe’s chassis.
However, the multiplexer channels can be
chassis grounded with a simple change.
Both 50-ohm and 75-ohm versions are
available.

34946A/47A—from DC to 26.5 GHz
For applications where you need only a
few high-frequency switches, the 34946A
and 34947A offer single-pole, double-throw
switches in either 4GHz, 20GHz or 26.5GHz
options. These modules internally mount
two or three independent Agilent N1810
series coaxial switches. These switches are
well known for their excellent insertion
loss, isolation and VSWR specifications.
Switch read back capabilities allow you to
query the position of the switch. You can
choose higher density with the unterminated switches, or select the terminated
switches to maintain impedance match.
34946A/47A option 001
These modules can also be ordered without switches installed. This give you the
capability to install your own N1810 series
switches or use the module to control the
N1810 Series switches outside the mainframe.

34945A/34945EXT microwave
switch/attenuator driver
This module allows you to control switches
attenuators, and other devices external
to the 34980A. The 34945A/ 34945EXT
provides the power and control signals
for many of the most popular microwave switches and attenuators. One
34945A/34945EXT combination can drive
up to 64 switch coils—that’s 32 standard
SPDT switches. The 34945A/EXT can be
extended by adding additional 34945EXT
boards. The first 34945EXT is powered by
the mainframe. You can add up to seven
additional 34945EXT boards with user supplied power. Multiple switch operations are
performed in sequential order, or for faster,
simultaneous switching, you can connect an
external power supply to the 34945EXT.
The Y1150A-Y1155A distribution boards
enable simple connections to the external
switches. The distribution boards plug onto
the 34945EXT and are used to route the
power and control signals from the driver
module to the switches using standard
cables.
The 34945A/34945EXT also has sensing
capabilities that allows read back of the
actual position of the switch or attenuator.
Drive signals for LED indicators are also
provided to give a visual indication of the
switch position.

34980A system control modules
34950A 64-bit digital
I/O with memory and counter
This module can be used to simulate or
detect digital patterns. It has eight 8-bit
digital I/O channels with handshaking, pattern memory, two 10 MHz counters with
gate functions, and a programmable clock
output.
Digital input/output
The digital I/O bits are organized into
two banks of 32-bits. The I/O bits can be
configured and programmed as inputs or
outputs in 8-bit channels. The digital outputs can be configured as active drive or
open drain outputs with a 10 kΩ pull up.
User supplied pull up resistors for up to 5
V outputs are also acceptable. The digital
inputs have programmable thresholds up to
5 V for compatibility with most digital logic
standards.
The onboard pattern memory can be used
to select and output digital stimulus or
bitstream patterns, or to capture external
digital data. Each bank has independent
memory and directional control so that one
bank can output data while the other
captures data. The memory can be divided
up to 64 Kbytes per 8-bit channel.

34951A 4-channel isolated
D/A converter with
waveform memory
This module has four independent, isolated
channels that output DC voltage up to ±
16 V or DC current up to ± 20 mA. The gain
and offset can be adjusted on-the-fly. Each
channel can be controlled manually, or use
the onboard memory to download a waveform. The 500k of memory is global and can
store up to 32 waveforms. Any waveform
can be dynamically allocated among one
or more channels and output as a point-topoint arbitrary waveform generator at up to
200k points/sec. You can use the standard
sine, square or ramp wave shapes provided
or define your own wave shape using over
500,000 points and output to a device under
test. There is also a single CLK that can be
divided down for each channel independently.
The calibration command connects the D/A
converters to the internal DMM to be automatically calibrated. Connections to the
module can be made via standard 50-pin
Dsub cables or a detachable terminal block.

< 0.8 V (TTL)
The multifunction module offers the flexibility you need for system control. The 34952A
has four 8-bit digital I/O channels, a 100kHz gated totalizer, and two ± 12 V analog
outputs—all on a single earth-referenced
module. The digital inputs and totalizer
input may be included in a scan list. Alarm
limits for the digital and totalizer inputs are
evaluated continuously, capturing and logging alarm conditions even between scans.
Connections can be made via standard
50-pin Dsub cables or detachable terminal
block. The 34952T terminal block has a
pinout for connection to an external Opto
22 board.

Definitions for specifications
Specifications describe the warranted performance of calibrated
instruments that have been stored for a minimum of 2 hours within
the operating temperature range of 0 °C to 50 °C, unless otherwise
stated, and after a 45 minute warm-up period. Data represented in
this document are specifications unless otherwise noted.
Characteristics describe product performance that is useful in the
application of the product, but that is not covered by the product warranty. Characteristics are often referred to as Typical or
Nominal values.
• Typical describes characteristic performance, which 80% of
instruments will meet when operated over a 20 °C to 30 °C tem
perature range. Typical performance is not warranted.
• Nominal describes representative performance that is useful in
the application of the product when operated over a 20 °C to
30 °C temperature range. Nominal performance is not warranted.
Note: All graphs contain measured data from several units at room
temperature unless otherwise noted.

T h e Mo d u l ar Tang r am
The four-sided geometric symbol that appears throughout this
document is called a tangram. This seven-piece puzzle originated
in China a few centuries ago. The goal is to create shapes—from
simple to complex—that form an identifiable silhouette. As with a
tangram, the possibilities may seem infinite as you begin to create
a new test system. With a set of clearly defined elements—architecture, hardware, software—Agilent can help you create the
system you need, from simple to complex.
