A new addition to the MagnaDC power supply product family brings high-power high-voltage isolated dc outputs in a compact 1U form factor, while also providing the option for universal single-phase ac input at 1.5 kW and 2.6 kW power levels. Applications include high-voltage inverter and traction controller testing, semiconductor validation and component test, downhole drilling, […]
Network analyzers incorporate high-performance signal generators for complex measurements
Enhanced PNA and PNA-X network analyzers contain a proprietary low-spurious direct-digital-synthesis (DDS) source, enabling users to take accurate measurements with less phase noise interference. With the clean source signals, users can perform two-tone IMD measurements with close tone spacing previously only possible with high-performance analog signal generators. The new DDS sources also enhance the performance […]
PXI matrix switch module hosts up to 9,216 crosspoints
The 1-A 40-562B BRIC12 PXI modules can hold up to 18 matrix daughtercards with up to 3,168 crosspoints. The 0.5-A 40-558 BRIC12 modules can also hold up to 18 matrix daughtercards, offering up to 9,216 crosspoints, making it the industry’s highest capacity PXI matrix switch module. Like previously available two, four and eight-slot versions, the […]
High-performance PXI multi-function instrument combines A/D, D/A and digital I/O
The new GX3788 High-Performance FPGA Multi-Function Instrument combines A/D, D/A and digital I/O functions. The GX3788 is a user-configurable 3U PXI hybrid slot compatible instrument, with flexible digital and analog test capabilities. The A/D channels can be configured as eight differential or 16 single-ended inputs and support sampling rates of up to 250 KS/sec. Alternately, […]
OpenVPX chassis platform supports standard OpenVPX and SpaceVPX boards
A new OpenVPX chassis platform supports both 160-mm-deep (standard OpenVPX) and 220-mm-deep (SpaceVPX) boards. The open-frame chassis features up to four slots at 1.0-in. pitch of each board depth type. The modular enclosure allows various board pitches to be utilized at 0.2-in. increments. Card guides to support both air-cooled boards and conduction-cooled boards are standard. […]
Photovoltaic array simulators deliver 20 kW in a 3U format
A new family of photovoltaic (PV) array simulators are the first to deliver 2,000 V and 20 kW of power in a 3U format, enabling engineers to maximize solar power conversion. To keep solar power at grid parity with competing methods of power generation, performance and power conversion efficiency are critical. Small increments in power […]
Fast PCIe digitizers get additional digital inputs
A new digital input option, M4i.44xx-DigSMA, for PCIe digitizers consists of an additional module that sits beside the existing digitizer card to provide eight additional digital input lines. The digital input module shares a common clock and trigger with the base card so both the digital and analog inputs are fully synchronous. This makes the […]
Regenerative power supplies handle up to 20 kW and 2,000 V
The RP7900 Series of regenerative power supplies has expanded with the introduction of two new bidirectional, regenerative dc power supplies providing integrated safety features that protect people and devices under test (DUT). The regenerative design of the new models enables the energy normally consumed to be returned to the grid cleanly, saving costs associated with […]
Finding fiber-optic cable anomalies
Optical fiber is a form of waveguide. The lateral dimension of a waveguide depends upon the wavelength of the signal conveyed. A waveguide is not capable of carrying a wavelength much larger than its diameter. Optical fibers are characterized by their core diameters. In single-mode fiber, the standard core diameter is 9 μm. Standard multi-mode […]
Say goodbye to National Instruments, hello to “NI”
National Instruments today announced an updated brand identity including a new logo, visual identity, enhanced digital experiences and a brand campaign celebrating engineers and engineering firms that “Engineer Ambitiously.” The company is now known simply as NI. One reason: NI vice president of global marketing Shelley Gretlein said the word “National” in the company name […]
