AC/DC power supply

The ASM400 Series high-density open-frame AC/DC power supply provides 400 W of regulated power in a 3-inch x 5-inch form factor. The power density of the ASM400 series results in a small footprint, making it flexible for use in powering portable medical equipment and numerous industrial applications.

The ASM400 Series is certified to IEC60601-1 third-edition BF isolation as a Class I (grounded) input with a Class II (nongrounded) input and 2 MOPP option. This power supply series is suitable for portable home medical use and direct-connect patient life-sustaining applications such as infusion pumps, ventilators, and portable dialysis machines. Features include a 5-V auxiliary and a 12-V fan output as well as a remote-on signal. Custom output voltages are available. Astrodyne TDI

E-band VNA option

An E-band option for the ShockLine MS46500B Series two- and four-port performance vector network analyzers (VNAs) addresses the market need to lower cost-of-test for E-band components. With the 55-GHz to 92-GHz option installed, the MS46500B series can reduce production costs and more efficiently verify the performance of high-frequency passive components, such as antennas, filters, and duplexers, during manufacturing.

In addition to the E-band frequency capability, the vendor also introduced 20-GHz and 40-GHz options for the ShockLine MS46500B Series. With these options, the MS46500B VNAs address the S-parameter and time-domain measurement requirements associated with microwave applications. Anritsu

RF vector signal generators

The VSG2G1 and VSG6G1 USB-connected portable RF vector signal generators provide features and functions comparable to full-size analog RF signal generators. Offering frequency ranges up to 2.2 GHz (VSG2G1) or 6.2 GHz (VSG6G1), the instruments can provide frequency sweep, frequency hopping using I&Q modulation, and arbitrary signal generation. Both of the VSGxG1 models are suitable for field test situations since they are compact and convenient and can be configured to operate without a connected PC. They also can operate in ATE systems as a signal-source module, simulating many different RF systems for test purposes. With output levels up to 10 dBm (Band 0&1), signals can be delivered in CW, sweeping, and hopping modes. The VSGxG1 RF vector signal generators are made by Triarchy Technologies. Saelig

DAQ application options

Three module options for the rugged SomatXR data-acquisition system include the MX840B-R Universal Module, developed especially for measurement tasks that require the use of multiple transducer types; the MX411B-R Highly Dynamic Module, suitable for highly dynamic acquisition and analysis of mechanical measurement quantities; and the MX471B-R CAN Module, designed for connecting the SomatXR data acquisition system to a CAN network.

All three new amplifiers have IP65/IP67 protection ratings ensuring they’re both dust- and water-tight. An extended operating temperature range (-40°C to +80°C or -40°F to +176°F) allows the amplifiers to work in a wide range of harsh environments. They meet MIL−STD-202G standards and are vibration resistant up to 10g and shock resistant up to 75g. HBM

Record and playback storage system

For applications requiring extended electronic waveform acquisition and generation, the Tera-Store storage system works with its PC-based digitizer and generator cards to increase possible recording and replay times. The new system can be used with any of the vendor’s M2i, M3i, or M4i series of PCIe digitizer or waveform generator cards and delivers data storage sizes from 1 to 32 TB with full support for continuous data streaming at rates up to 3 GB/s. The combination makes it possible to capture high-frequency signals up to the GHz range and continuously store them for hours or lower frequency signals for even longer periods of time. Spectrum

Bluetooth resistance testers

The DET24C earth/ground digital clamp-on resistance tester now includes Bluetooth. This upgrade allows users to download stored test results instantly to a PC instead of downloading them using an IrDA interface. Using Bluetooth V2.0 and enhanced data rate, data from the DET24C no longer needs to be transferred using a USB dongle, making the process faster and more convenient. PowerDB Lite software, which comes standard with the instrument, also has been updated to enable users to select the download method of their choosing. Megger

Hearing-aid charger-receiver

The LTC4123 combines a 30-mW wireless receiver with a constant-current/constant-voltage linear charger for NiMH batteries, such as Varta’s power one ACCU plus series. An external resonant LC tank connected to the LTC4123 enables the IC to receive power wirelessly from an alternating magnetic field generated by a transmit coil. Integrated power management circuitry converts the coupled AC current into the DC current required to charge the battery. Wireless charging with the LTC4123 allows for a completely sealed product and eliminates the need to constantly replace primary batteries. Zn-Air (Zinc-Air) detection enables applications to work interchangeably with both rechargeable NiMH batteries and primary Zn-Air batteries with the same application circuit. Linear Technology

PCB enclosure

The EXN Series enclosure is made of an anodized aluminum extrusion with plastic or aluminum endcap covers. Removal of the cover allows a user-supplied printed-circuit board to slide in. The extruded aluminum construction has grooves that enhance heat dissipation. The enclosures are suitable for use as instrument cases and for housing electronic power supplies, remote controls, and a variety of factory-floor and outdoor applications. Included continuous gaskets seal against weather and water, allowing the enclosures to be used outdoors or indoors in wash-down and dusty environments. Bud Industries
