Switch Modularity & Interface Platform (SMIP

TM

)

Reduces the Size and Cost of ATE

Overview

There are many different types of Automated Test Equipment (ATE) systems available to help manufacturers improve production quality and throughput. Although these test stations are used in different applications, they all share one common denominator - a signal switching system - that directs the 'input/output traffic' between the test stand instrumentation and the devices being tested.

The budget allocated to ATE for manufacturing test, or even for service and repair, is considered part of the overhead in bringing the final product to market. Reducing this cost, therefore, is an important consideration. The goal of meeting the budget can be achieved by decreasing the purchase price of the ATE station, or increasing its throughput (i.e., increase the number of units being tested per day).

With advancements in technology and competitive constraints increasing, the need to drive overhead costs down has intensified.

Modular high-density VXIbus instruments such as the VMIP TM family have helped improve the size, cost and throughput of VXIbus systems with virtually every new test station being designed today utilizing modular VXIbus instruments. The SMIP TM family switching system has leveraged off this trend in modular instruments continuing to improve the cost/benefit ratio of the production test cycle.

The Advantages of “Next Generation"

Signal Switching (SMIP

TM

Series)

Reduced System Size and Cost - Density and

Modularity

There are numerous standards and platforms for ATE equipment, and price and performance are key factors in determining the correct platform for the application.Whenever a large amount of signal switching is required in an ATE system,VXIbus always makes cost-effective sense, and in many cases helps justify the decision to select a VXIbus system. While first generation VXI products had made very real and measurable improvements in ATE signal switching, the "next generation" of signal switching systems driven by the SMIP TM series is vaulting the VXIbus to a higher level in terms of performance, density and value.

First generation VXIbus switch cards contain one switch configuration per card slot (e.g., 32 SPDT, 64x1 2-wire scanner,

4x64 matrix), very similar to first generation VXIbus instruments.

These switch systems are typically GPIB/VME-based products converted over to the VXIbus. The SMIP TM series is designed exclusively for the VXIbus, and takes advantage of the recent advancements in relay and driver technology, providing higher performing switches in a smaller footprint.

The SMIP TM family provides a level of modularity and density that is unfamiliar in first generation VXIbus cards, and reduces the number of slots used in a VXIbus mainframe.

A recent application testing engine control modules called for the following switch requirements and demonstrates the size and cost advantages of the SMIP TM family, compared to first generation

VXIbus switch systems from other manufacturers:

The SMIP TM series builds the intelligence (scan lists) into the hardware registers. The time delta between TTL trigger in

(command to close the relays) and TTL trigger out (indicating relays have settled) is effectively reduced to the settling time of the relay itself (about 3-5 ms). An excellent example highlighting the effectiveness of this technique was demonstrated by a defense contractor exercising a missile simulator (See Figure 2). Stimulus is applied to the launch sequencer via a Form C switch. The launch sequencer replies with an 'initiate fire ready' command and the stimulus must be removed to ground within 10 ms. The only viable solution was to use a switch card with its scan list and control built into the hardware, as the latency times were well within the window of acceptance. The switch card selected in this case was

12x24 matrix to connect engine control module I/O to test station

64-channel multiplexer connecting DMM to multiple measurement points

240 Form C Relays for high-density general purpose switching

The three VXIbus switch systems proposed are detailed in Figure 1.

The ‘first generation’ system occupies seven slots, whereas the modular switch system (SMIP TM ) occupies only three.

SM5002

Stimulus Source

The SMIP TM was selected because an additional four slots were freed up for instrumentation purposes, and also because the switches are rated for 2A as opposed to 1A for the switches in the first generation system. Additionally, this system could have been reduced to a six-slot mainframe, had portability been an issue.

Subsequent hardware costs are considerably reduced (30-40%) because the modular system utilizes shared resources (i.e., connectors,VXIbus interface, sheet metal, etc.).

The VXIbus offers tremendous advantages in reducing test cycle times because the instruments and switches share a common backplane. The VXI specification reserves eight lines dedicated to triggering back and forth between instruments. VXI switch cards that utilize scan lists (a sequence of relay states) can then be triggered to advance through this list by an instrument on the bus.

Figure 2

For example, test specifications of a device often require the verification of continuity or isolation between connector pins. A

DMM is most often the instrument used to verify the results. The continuity/isolation test can involve a large number of pins. Thus, the DMM needs to be switched to a connector pair and take its measurement before moving to the next pair. This sequence of events can take a significant amount of time, due to the overhead in handshaking between the DMM and the switch card, particularly if pre-programmed scan lists are not utilized. By utilizing a VXI-based card with a scan list, all handshaking can be done across the backplane, and since the scan list is stored in memory, no software overhead is incurred. Large channel counts can be scanned in a fraction of the time through the use of on-board scan lists.

VXI Technology's SM5002.

(1) Stimulus is applied to the sequencer via the normally closed contact of a Form C relay on an SM5002 card.

(2) The sequencer processes the data and issues an ‘initiate fire’ command, sending out a pulse on TTL0 of the VXI backplane.

The Time Stamp module records TTL0 pulse as t0.

(3) The SM5002 also detects the pulse on TTL0 and the relay changes state.

(4) The SM5002 issues a 'relay settled' pulse on TTL1, which the Time Stamp records at t1. Dt (t1-t0) needed to be less than 10 ms to meet specification for this application (verified to be under 3ms).

This was compared to a Dt of over 40ms from a switch module that used an intelligent interpreter plug-on card.

Conclusion

GPIB and first generation VXI-based switch cards implement scan list capabilities in a couple of different ways. A GPIB switch or messagebased switch card requires an 'intelligent interpreter' that usually takes the form of a plug-in card. Scan lists are stored on this card and message-based commands are parsed by the interpreter.

Traditional register-based switch cards must have a driver downloaded to the slot 0 controller and this driver acts as the interpreter. In both cases,ASCII strings (messages) are sent via the host controller to set up the switch card and scan list. There is also a relatively substantial amount of latency between the time a trigger is received by the switch card and the time that the card issues a trigger to the backplane indicating that the relays have settled (10-40ms).

In the past decade,VXIbus switching systems have grown to become a significant part of Automated Test Equipment because of the ability to fit a large number of switches on a card. But test instrumentation consumers are continually demanding product that is faster, smaller and less expensive. Innovative hardware designs greatly ease the burden placed on production engineers by cutting down on test cycle time, and further reducing hardware costs.The SMIP TM series is leading the way to meet the expectations of customers by taking advantage of the latest relay technology yielding higher performing switches in a smaller footprint. Modular switch cards provide the systems engineer the flexibility to design a system that optimizes space while keeping down the overall price.

Overview

The SMIP TM is designed with modularity, density and cost in mind.

Unlike "first generation" VXIbus switching solutions, the SMIP TM family consists of switch modules that can be mixed and combined within a VXIbus card to form flexible and high-density switch configurations.The SMIP TM family reduces the size of switching solutions by at least 30%, and the overall cost by at least 20% compared to solutions from other manufacturers - regardless of their platform (GPIB,VME,VXI or PC).

Each SMIP TM base unit includes a switch control interface board, which has one of the most advanced switch control designs on the market. The interface has been designed to provide all the features of an intelligent message-based switching system, but with the speed and flexibility of a register-based device.These features are achieved in hardware on the control interface board, rather than in a driver or via on-board microprocessor based firmware.This

approach to the interface design guarantees the user that all communications to the switch occur in microseconds, as opposed to several milliseconds, considerably improving system throughput.

Product Brief

Switch Modularity & Interface Platform (SMIP TM )

The advanced register-based interface design allows new switching modules to be introduced into the product family without the need to reprogram EEPROMs or exchange control modules, as is common with other switching systems.

The SMIP TM interface supports direct register control of all relays, the ability to download scan lists with backplane trigger advance, and hardware implemented break-before-make and make-beforebreak switching. By using direct register access, switching speeds are maximized while keeping VXIbus backplane traffic to a minimum. By using the trigger feature, large switching systems across multiple mainframes can be controlled with a single command.

The supplied VXIplug&play drivers provide support for higher level commands and a unified switch interface.

Signal Integrity

All SMIP TM switch modules have been designed with over a decade of experience in signal switch design and are optimized to preserve signal integrity.All switch modules employ multi-layer

PCB designs with extensive ground planes and shielding where appropriate, with relays also being selected to maximize signal integrity. Signal ground planes are isolated from the control circuit grounds, and signal paths are designed to minimize crosstalk between channels.To further minimize any digital noise, the control circuitry goes into a quiescent state when not processing commands, making it possible to switch low-level signals. Mating connector shrouds are also available to permit cable harnesses to be crimped, soldered or connected via terminal blocks, so the user can select the best method of cabling for the application.

Programming

The SMIP TM family of switch modules is programmed using direct register access for fast data throughput and boasts the following features for easy programming and integrating of the SMIP TM family:

Automatic Scanning: A predefined sequence of channels or set-ups can be programmed into 1 Mbyte of RAM, and can be incremented by software or hardware trigger sources.This approach relieves the host controller from having to tie up the VXIbus backplane when scanning.

Programmable Timing Delays: A delay can be programmed between relay closures to allow for settling times of other system resources.When used with triggers and automatic scanning, a controlled synchronous switching system can easily be configured.

Confidence Checking: Internal feedback provides confidence of relay closures.

Extensive Triggering: Triggers can be generated when a relay closes and settles, and programmed relays can be actuated upon receipt of a trigger to allow for synchronization between other devices. Since trigger management is performed in hardware, triggers command a relay to open or close within microseconds, as opposed to several milliseconds from other competing systems that support triggers.

Make-Before-Break and Break-Before-Make: Relay control implemented in hardware eases software burden, and considerably improves system throughput.

Safety Interrupt: This is a programmable fail-safe feature that allows all relays to open based upon external or TTL backplane triggers. Signals can be removed from the unit under test if a system fail-safe occurs, such as inadvertent removal of a test adapter.

Non-volatile Memory: Allows users to store pertinent information such as maintenance records, relay specs, installation dates, serial numbers and last user’s id.

The SMIP TM family is comprised of three distinct switching groups divided by frequency range. Each switching group has its own base units designed to maximize the modularity and flexibility of switching within that frequency range. Switch control and programming features remain consistent with the overall SMIP TM family.

Overview

The SM2007 is designed for scanning high-voltage multiple points to a common bus in either 1- or 2-wire configurations, either synchronously with an instrument (i.e., using triggers), or asynchronously with individual relay control. Up to 144 2-wire (or

288 1-wire) channels can be accommodated in a double-slot VXIbus card (SM1000B) for maximum density, or mixed and matched with other SMIP TM cards for flexibility. Applications include Hipot or cable breakdown testing.

When switching high voltages, the need for signal shielding becomes critical. The SM2007 has been designed to include large shield planes to improve crosstalk and voltage spikes to adjacent channels.

For ATE applications, such as switching high-voltage source measure units or power supplies, a fail-safe interrupt line is provided on the front panel.This can open all relays automatically if a safety condition occurs. This approach instantly removes all high voltages to the UUT or interface.

The SM2007 consists of 2 individual (1x12) 2-wire multiplexers, or 2

(1x24) 1-wire multiplexers that can be interconnected under program control (via the bussing relays) to configure larger multiplexers as required.This eliminates external wiring and helps reduce unterminated stubs. All relays are also driven from the VXIbus

Overview

The SM3001 high-density multiplexer module is designed for scanning of multiple points to a common bus, in either 1- 2- or 4wire configurations, either synchronously with an instrument (i.e., using triggers), or asynchronously with individual relay control. Up to 384 2-wire (or 768 1-wire) channels can be accommodated in a double-slot VXIbus card (SM1000B) for maximum density, or mixed and matched with other SMIP TM cards for flexibility. Applications include cable harness testing, semiconductor and PCB testing, or applications where multiple points need to be switched to a common resource. All relays also have individual relay control, and each path allows for 2A switching.The SM3001 consists of 8 individual (1x8) 2-wire multiplexers, or 8 (1x16) 1-wire multiplexers that can be interconnected under program control (via the bussing relays) to configure larger multiplexers as required.This eliminates external wiring and helps reduce unterminated stubs. All relays are also driven from the VXIbus +5V supply line, since VXIbus mainframes always have ample current capacity on this supply line, as opposed to the +24 or +12V supply lines.

Internal residual voltage discharge relays can be enabled to momentarily short out the measurement path when changing from one input channel to the next.This dissipates any voltage held by the wiring and instrument input capacitance. These relays protect sensitive devices, such as CMOS circuits, from residual voltages caused by previous high-voltage measurements.This feature can also be disabled in low-voltage applications where maximum throughput speed is important.

Matrices

Overview

The SM4000 series high-density matrix modules are designed for applications that require a true non-blocking matrix, where the user has the ability to connect any row to any column.The smallest building block is a (4x4) 2-wire matrix, and rows and columns can easily be expanded to form larger matrices. A (4x216) 2-wire matrix can be accommodated in a double-slot VXIbus card

(SM1000B) for maximum density or mixed and matched with other

SMIP TM cards for flexibility. All relays also have individual relay control allowing multiple inputs to be connected to multiple outputs, with each path allowing for 2A switching.

Various configurations are shipped from the factory, and the user also has the capability to define a custom configuration using the available 9 (4x4) building blocks.

Complete block diagrams for each configuration can be found in the SMIP TM manual.

Overview

These high-density basic switch modules are designed for general purpose switching where individual relays can be used to route signals to/from the units under test (UUT), or combined externally to form user-defined configurations.The latter approach allows the same switch module to be used for testing multiple UUTs by simply changing the configuration within a UUT-specific external adapter. Up to 480 individual SPST relays, 300 individual SPDT, or

156 SP4T relays can be accommodated in a double-slot VXIbus card (SM1000B) for maximum density, or mixed and matched with other SMIP TM cards for flexibility.

All relays are driven from the VXIbus +5V supply line, since VXIbus mainframes always have ample current capability on this supply line, as opposed to the +24 or +12V supply lines.

VXIbus card (SM1000B) for maximum density, or mixed and matched with other SMIP TM cards for flexibility.

All relays are driven from the VXIbus +5V supply line, since VXIbus mainframes always have ample current capability on this supply line, as opposed to the +24 or +12V supply lines. Since these modules typically switch power to the UUT or interface, a fail-safe interrupt input line is provided on the front panel that can open all relays automatically if a safety condition occurs.This approach instantly removes all power to the UUT or interface.

Precise switching of optical channels is achieved in the SM8001 and

SM8002 multi-channel switch modules using diffraction limited collimating lenses, which enhance both thermal stability and repeatability.The SM8003 single-mode prism switches provide channel selection from one input fiber to either one or two output fibers using a moving prism between fixed collimator pairs.

SM8001 and SM8002

The SM8001 and SM8002 can each hold up to 2 optical switch modules. Each switch module can be either a 1xN (where N ranges from 2 to 17) or a 2xN (where N ranges from 2 to 8). Selecting between the SM8001 and SM8002 is dependent on the required number of front panel I/O connectors for the desired configuration.

Overview

The SM8101 and SM8102 are single-slot VXIbus modules. The

SM8101 is a single-channel variable attenuator, whereas the SM8102 is a two-channel variable attenuator. Both modules are used to automatically adjust optical power level in test systems with a range

0 to 60 dB, with better than 0.05 dB resolution. Applications include setting power levels to optimize receiver sensitivity in single wavelength systems, as well as active gain equalization in dense

WDM systems. Factory test applications include bit error rate performance and dynamic range testing.
