Flexible switching, measurements, and system control
The 34980A accommodates up to 8 plug-in modules to give you the flexibility you need. Choose from 21 different modules to define your own configuration. You can buy what you need now and add to it or reconfigure it as your requirements change.
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.

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. 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.
* Built-in thermocouple reference for temperature measurements (34921T) * Time-stamped readings * Add more formulas with BenchLink Data Logger Software The integrated DMM is mounted inside the mainframe and does not consume any of the eight useravailable 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 * Frequency and period * 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 earth-referenced 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.
Modules provide flexible system stimulus and control
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. 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 on-board memory you can output communication protocols and bit streams or monitor digital input patterns and interrupt when a userdefined pattern is detected.
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: * 612 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

Standard interfaces take the hassle out of connecting to your PC
Standard Ethernet, USB and GPIB interfaces are included in every mainframe. Use one of the built-in interfaces that is already available in your computer, or if you prefer, GPIB is still available. * USB offers the quickest and easiest connection scheme--it's perfect for small systems and bench connections. * Ethernet offers high-speed connections that allow for remote access and control. Choose a local area network to filter out unwanted LAN traffic and speed up the I/O throughput. Or take advantage of the remote capabilities and distribute your tests worldwide. Use the graphical Web browser to monitor, troubleshoot, or debug your application remotely. * GPIB has many years of proven reliability for instrument communication and can be used in existing GPIB based test systems.
Remote access and control
The built-in Web browser interface provides remote access and control of the instrument via a Java-enabled browser such as Internet Explorer. Using the Web interface, you can set up, troubleshoot, and maintain your system remotely. * View and modify instrument setup * Open, close, or monitor switches * Send SCPI commands * Define and execute switch scans and switch sequences * View error queue * Get status reports on relay counts, firmware revisions, and more Additionally, since the Web interface is built into the instrument, you can access it on any operating system that supports the Web browser without
having to install any special software. Password protection and LAN lock out are also provided to limit access. The Web interface makes it easy to set up, troubleshoot and maintain your system remotely. Works with your choice of software so you can save time and preserve your software and hardware investments. Program directly with SCPI, or use IVI or LabVIEW software drivers that provide compatibility with the most popular development environments and tools: * Agilent VEE Pro, Agilent T&M Toolkit (requires Microsoft(R) Visual Studio(R).NET) * National Instruments LabVIEW, LabWindows/CVI, TestStand, and Switch Executive * Microsoft Visual Studio.NET, C/C++ and Visual Basic 6

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 break-before-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.

34980A matrix switch modules
The 34980A matrix modules are full cross-point matrices that allow you to connect any row to any column. This is a convenient way to connect multiple test instruments to multiple points on a device under test. Choose from the following features: * Latching armature relays--300 V, 1 A * High-speed reed relays--150 V, 0.5 A * Configurable dual 4x8, dual 4x16 or quad 4x32 modules * Single-wire configuration (34933A or 34934A) * High density matrix with automatic surge protection and row disconnect for flexible measurements (34934A) * Analog bus expandable rows to create larger matrices (34931A, 32A, 33A) * Connections via standard 50 or 78-pin Dsub cables or detachable terminal block 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.

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 * Simultaneous channel switching * 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 general-purpose 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 * DC to 3 GHz * 30 V, 0.5 A, 10 W
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.

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. The following microwave switches and attenuators are supported with the Y1150A-Y1155A distribution boards: * N181x/U9397x series SPDT switches * 8762/3/4 series SPDT switches (screw terminals) * 8765x coaxial switches * 8766x/8767x/8768x multiport switches * 87104x/106x/L710xx/L720xx multiport switches * 87406x series matrix switches * 87204x/206x series multiport switches * 87606x series matrix switches * 87222x/L7222 transfer switches * 849x and 8490x series attenuators * Other switches and devices through individual screw terminal connections

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.
