Are Standalone Instruments Going Away?
Are Standalone Instruments Going Away?

One maker of modular instruments surveyed test managers among its customer base and found that while 70% use traditional "rack-and-stack" systems based on standalone instruments, only about 30% expect to be purchasing any new such systems going forward. Conversely, about 30% use PXI-based systems (a modular test architecture) today, but about 70% plan to be moving to PXI in the future. This doesn't mean that standalone instruments will disappear completely. They're still the instruments of choice for bench-type laboratory work. But it does seem to indicate that their future may be limited in automated production test environments.

Supported by ReDAQ® Shape software, the 8B isoLynx® SLX300 features sustained I/O up to 3.0 kS/s (100 kS/s burst), seven advanced special functions, Modbus RTU/TCP support, and 1500 Vrms input-to-output and channel-to-channel isolation.

Modules Bring Functional to In-circuit Testers

Modules Bring Functional to In-circuit Testers Recognizing the need to increase in-circuit fault coverage while avoiding the extra handling burden necessitated by adding a separate functional tester, this company now offers PXI expansion boards for their in-circuit products. The approach supports any test capability that conforms to the PXI standard. Users can even take advantage of test solutions from other vendors.

PXIe Chassis Gets Bigger

Turbulence Modeling Tames Tight Turbines The extreme flexibility of a standard such as PXIe comes at a price. How do you select a chassis and configure your system to take advantage of all of its capabilities? First you need a chassis with enough room for all the functions you plan to use. This one includes 16 hybrid slots, accommodating both PXI and PXIe modules. A data-transfer rate of 8 GB/second permits any PXI test system to download complex waveforms in a quarter of the time of previous generations.

Testing ICs Without Breaking the Bank

Turbine Transformer Tips Despite the ever-declining size and cost of manufacturing semiconductor devices, the cost of test stubbornly refuses to decline at anything near the same rate. One solution is to assemble flexible test systems by incorporating modules and software that communicate over the PXI bus. This article offers some practical suggestions and presents several real-world examples of this solution.

Power Supply for Test on an AXIe Card

Bird and Bat Science Here's a power supply on a single card that conforms to the AXIe standard that is flexible enough for a wide variety of test applications. Its two banks of six channels each provide three selectable modes — positive, bipolar, and negative. Each channel offers four wire Kelvin connections, including active guard, and programmable voltage ramp and current clamps, along with force-voltage-measure-current, force-voltage-measure-voltage, and force-nothing-measure-voltage capability.

Testing the Latest Mobiles

Taming Transport Bottlenecks Having provided PXI-based test equipment for previous generations of mobile technology, Aeroflex has introduced a complete line of solutions to handle 4th generation long-term-evolution (LTE) technology. The TM500 mobile family has been adopted by most of the major LTE base-station manufacturers, while their Digital Radio Test Set verifies performance of user chipsets. The instruments are completely backward compatible with their 3G predecessors.

Modular Instruments — Another Point of View

Ultra-capacitors Make Their Pitch Like software instruments, modular instruments have become more popular because they provide more flexible test capability, yet keep costs down. Modularity allows faster instrument development to keep up with customers' ever-changing needs, while providing advantages such as smaller footprint and faster execution speed. And, as this article points out, the growth of modular solutions could not have occurred without the evolution of RF components.

A DSO Upgrade That Doesn't Forget the Past

Driving Drivetrain Reliability Bowing to the need for more memory and faster sample rate, ZTEC has enhanced their line of digital storage oscilloscopes, while assuring customers of an upgrade path and backward compatibility. The LXI platform for the instruments will feature support for Gigabit Ethernet, a faster embedded processor, a monitor output for displaying waveforms, and on-site software updates.
