Key Features
Reconfigurable Topologies
As referenced in Table 1, many PXI Matrix Switch Modules can be reconfigured to achieve multiple topologies within a single device, allowing
you to select the topology that best suits your application. For example, the PXIe-2532B can be reconfigured into various matrix topologies,
ranging from a single 4x128, 1-wire matrix to a 16-bank 2x16, 1-wire matrix.

Synchronization and Integration
NI switches use the inherent timing and synchronization capabilities of the PXI platform to communicate with other instruments within the PXI
chassis. Triggering is available on most NI switches. To check if this feature is supported by a switch module, reference the “Trigger
Characteristics” section of the product specification document.
You can store a list of switch connections in memory onboard the switch module and then use the integrated hardware scanning andtriggering engine to advance the switch sequence and rapidly communicate with any PXI instrument that can send and receive digitaltriggers, such as DMM or oscilloscope. This advanced switching method removes the software overhead and reduces the bus latency
associated with traditional software-controlled switching operations for faster test execution with more repeatable timing.

To simplify relay maintenance and increase reliability in high-channel-count systems, NI PXI Matrix Switch Modules offer advanced relay
health monitoring features, such as onboard relay count tracking, which is available on all NI switch modules, and functional and resistive selftests, available through the NI Switch Health Center.

FIGURE 4
The NI Switch Health center provides advanced relay health monitoring options, including functional and resistive self-tests, onboard relay count tracking, and report
generation.

The NI Switch Health Center is available on some NI switches. To check if this feature is supported by a switch module, reference thefollowing KnowledgeBase article: Which NI Switch Modules Support Resistive Self Test and Temperature Monitoring?
The NI Switch Health Center is a free application that installs with the NI-SWITCH driver that can be used to monitor individual relay health,guide relay replacement, and generate user reports. The NI Switch Health Center verifies the condition of each relay by sending a signal
through a combination of routes and alerting users if a relay has failed stuck open or closed. Additionally, large changes in contact resistanceover time can indicate that a relay is approaching, or has reached, the end of life. The NI Switch Health Center tests for changes in resistanceusing the integrated relay resistance test, allowing you to view the resistance change across individual relays and determine whether a relay isnearing the end of its usable life. A large change in resistance from the baseline indicates that you will soon need to replace the relay.
For more information on the Switch Health Center, relays, or switch topologies, see the NI Switch Health Center white paper.

Built for Automated Test and Measurement
PXI RF Relay Modules offer single-pole double-throw (SPDT) and terminated switches. SPDT models include excellent insertion loss, voltage
standing-wave ratio (VSWR), and isolation parameters to minimize signal degradation. You can use the onboard relay count tracking featureon these models to predict relay lifetime and reduce unexpected system downtime. SPDT models are also well suited for passing high-orderharmonics from PXI RF Signal Upconverter Modules or routing multiple sources to PXI RF Signal Downconverter Modules. Terminated switch
models feature front-mounted SMA connectors and high-performance solid-state relays for fast switching time and unlimited mechanicallifetime. These models also include termination on every COM line and channel, which helps minimize reflections of the RF signal and protect
your instruments.
Additionally, NI switch modules offer advanced features, such as hardware triggering, onboard relay count tracking, and a wide variety ofreconfigurable models, providing you the option to modify the topology of the switch based on your needs. These advanced features offer asmarter way to tackle difficult applications in industries ranging from consumer electronics to aerospace and defense.

Synchronization and Integration
NI switches use the inherent timing and synchronization capabilities of the PXI platform to communicate with other instruments within the PXI
chassis. Triggering is available on most NI switches. To check if this feature is supported by a switch module, reference the “Trigger
Characteristics” section of the product specification document.
You can store a list of switch connections in memory onboard the switch module and then use the integrated hardware scanning andtriggering engine to advance the switch sequence and rapidly communicate with any PXI instrument that can send and receive digitaltriggers, such as DMM or oscilloscope. This advanced switching method removes the software overhead and reduces the bus latency
associated with traditional software-controlled switching operations for faster test execution with more repeatable timing.

Key Features
Relay Health Monitoring
To simplify relay maintenance and increase reliability in high-channel-count systems, NI Matrix Switch Modules for SwitchBlock offer
advanced relay health monitoring features, such as onboard relay count tracking, which is available on all NI switch modules, and functional
relay self-tests, available through the NI Switch Health Center.

The NI Switch Health Center is a free application that installs with the NI-SWITCH driver that can be used to monitor individual relay health,guide relay replacement, and generate user reports. The NI Switch Health Center verifies the condition of each relay by sending a signal
through a combination of routes and alerting users if a relay has failed stuck open or closed.
For more information on the Switch Health Center, relays, or switch topologies, see the NI Switch Health Center white paper.

Designed for Matrix Expansion
The customizable hardware design of the NI SwitchBlock makes it easy to create large switch matrices in PXI while minimizing wiring,
simplifying connectivity, and providing a high degree of flexibility for your switching needs. A SwitchBlock system comprises a PXI Carrier
Module for SwitchBlock (PXI-2800) that occupies four PXI slots and can hold up to six 1-slot or three 2-slot Matrix Modules for SwitchBlock.
The PXI Carrier Module for SwitchBlock features a hybrid-compatible connector on the back of the second PXI slot which allows you to place
it in a PXI chassis or in a hybrid-compatible slot of a PXI Express chassis.

FIGURE 25
The PXI Carrier Module for SwitchBlock (PXI-2800) occupies four PXI slots, can hold up to six 1-slot Matrix Modules for SwitchBlock, and has an integrated analog bus
designed to combine those matrix modules into a single large matrix, without additional external wiring.

The PXI Carrier Module for SwitchBlock (PXI-2800) has an integrated analog bus, allowing for easy matrix expansion without the need for
additional external cabling. Each Matrix Module for SwitchBlock has analog bus relays that connect its rows to the analog bus of the carrier,effectively combining any matrices that are connected to the analog bus.

FIGURE 26
SwitchBlock is designed for easy matrix expansion, allowing up to 2,000 crosspoints in a single PXI Carrier Module for SwitchBlock (PXI-2800). Simply close the analog bus
relays to connect that Matrix Module for SwitchBlock with any other devices connected to the analog bus.

ni.comPXI Switch Modules

26Each Matrix Module for SwitchBlock is available in Type A and Type B configurations. The connector on the Type A card provides user
access to the columns of the relay card as well as indirect row access, through the analog bus of the carrier. To preserve system bandwidth,
Type B cards do not connect the analog bus to the front connector and only provide access to the columns through the front connector.
Type A cards allow access to the rows of the matrix indirectly through the analog bus, via the analog bus connector pins. To optimize
bandwidth, only one Type A card can connect to the analog bus at a single time, so most large SwitchBlock matrix systems have a single
Type A card, and the rest are Type B cards of the same model number.

FIGURE 27
Type A modules provide column access and row access through the front connector, allowing for row-to-column connections and column-to-column connections.
Conversely, Type B modules only provide column access and are restricted to column-to-column signal routes, unless joined to a Type A card through the analog bus.

A single PXI Carrier Module for SwitchBlock can create a 2,000-crosspoint matrix in four PXI slots. For larger matrices up to 8,000
crosspoints in an 18-slot PXI chassis, you can combine multiple PXI Carrier Modules for SwitchBlock by inserting a SwitchBlock Expansion
Bridge (NI-2806) between two or more PXI Carrier Modules for SwitchBlock.

FIGURE 28
To create larger matrices, you can connect the analog buses of multiple PXI Carrier Modules for SwitchBlock by inserting a SwitchBlock Expansion Bridge (NI-2806)
between the two or more PXI Carrier Modules for SwitchBlock. However, you must remove the analog bus cover before inserting the SwitchBlock Expansion Bridge.

Drive External Relays
The PXI Relay Driver Module is capable of driving 64 external relays, including high-current, high-voltage, multipole, RF relays, and more. You
can use the external relays independently as individual relays or combine them in a unique way to create a custom topology, such as amultiplexer or fault insertion unit (FIU).
The PXI-2567 can provide up to 50 V and 600 mA of drive capacity per channel when connected to an external power supply. Without anexternal power supply, it can source up to 1.25 A from the 5 V pin or 500 mA from the 12 V pin provided by the PXI backplane. For added
protection, the eight banks of eight relay drivers are protected against overvoltage and overcurrent conditions. When the condition clears, thechannel is automatically reset so no disassembly of the module is required. Additionally, a Zener diode is included to protect against damage
from inductive loads.

Key Features
Hardware Fault Insertion
In many hardware-in-the-loop (HIL) test systems, hardware fault insertion or signal insertion is used to create signal faults between theelectronic control unit (ECU) and the rest of the system to test, characterize, or validate ECU behavior under specific failure conditions. Fault
insertion is most commonly used when it is imperative for a specific ECU to have both a known and an acceptable response to fault
conditions—examples include ECUs for vehicles, aircraft, spacecraft, and machinery. To accomplish this, fault insertion units (FIUs) are
inserted between the I/O interfaces of a test system and the ECU so the test system can switch between normal operation and fault
conditions such as a short to battery, short to ground, or open circuit.

FIGURE 36
An FIU can insert fault conditions between automated test equipment, such as hardware-in-the-loop simulation systems and devices under test. This FIU schematic is
capable of numerous example faults, including open circuit fault, short to ground, short to power, and pin-to-pin short.

Synchronization and Integration
NI switches use the inherent timing and synchronization capabilities of the PXI platform to communicate with other instruments within the PXI
chassis. Triggering is available on most NI switches. To check if this feature is supported by a switch module, reference the “Trigger

Fully Programmable Resistance
Programmable resistors are test modules that replicate the behavior of resistance-based inputs and outputs such as potentiometers, RTDs,
voltage dividers, and bridge elements. The total resistance across each channel, measured across the front connector terminals, is controlled
by manipulating the circuit path resistance using relays to selectively route through discrete resistors. PXI Programmable Resistor Modules
programmatically control the values of resistance appearing through an I/O connector, enabling usage in hardware-in-the-loop (HIL)
validation, which performs rapid system tests during a variety of simulated system conditions.

FIGURE 43
PXI Programmable Resistor Modules use banks of series resistors with optional, low-resistance parallel paths, enabled or disabled through relay actuation.

NI-272x Reference VIs
Low-level control of individual relays is available through NI-SWITCH driver, which supports LabVIEW, C, C#, and others. However, this will
require manual calculations, control of individual relays, and low-level programming, which is not ideal for quick resistance or temperaturechanges. For a higher-level starting point, use the NI-272x driver, which is available for LabVIEW and includes reference VIs and example
programs for using a PXI Programmable Resistor Module as an RTD simulator, programmable potentiometer, or low-power resistive load.

A Platform Approach to Test and Measurement
Powered by software, PXI is a rugged PC-based platform for measurement and automation systems. PXI combines PCI electrical-bus
features with the modular, Eurocard packaging of CompactPCI and then adds specialized synchronization buses and key software features.
PXI is both a high-performance and low-cost deployment platform for applications such as manufacturing test, military and aerospace,machine monitoring, automotive, and industrial test. Developed in 1997 and launched in 1998, PXI is an open industry standard governed by
the PXI Systems Alliance (PXISA), a group of more than 70 companies chartered to promote the PXI standard, ensure interoperability, andmaintain the PXI specification.
