Single-Slot VPX Board

Elma Electronic (Fremont, CA) offers a dual-drive VPX storage module that provides more than 2 terabytes (TB) of storage, but requires only one system slot. The 533x family comes with either solid state SLC, MLC, or 2.5" rotating drives.

Thermal Analysis Tool

A Thermal Analysis tool from Custom MMIC (Westford, MA) estimates the rise in temperature between the ambient surrounding and the bottom of a packaged MMIC when attached to a printed circuit board (PCB). The online calculator does not require a full 3D thermal simulation environment. Users select the package type, the power dissipation inside the package, the PCB board material, the via construction, and the base plate temperature (typically 85°C). The calculator then determines the temperature rise through the PCB to the bottom of the package, under the following assumptions: the PCB is plated with 1 oz. copper (1.4 mils thick), the package is attached to the PCB with solder (2 mils thick), and the base plate is an ideal heat sink.

Rotary Micro Drive

New Scale Technologies (Victor, NY) has announced a prototype rotary piezoelectric micro drive system. Unlike servo drives, the new rotary drive has no measurable jitter, holds position without power, and generates no magnetic fields. The 44 × 44 × 36 mm prototype operates at 350 degrees/second and has an acceleration of 3000 degrees/second2.

Microwave Analog Signal Generators

Agilent Technologies (Santa Clara, CA) has introduced two microwave analog signal generators: the N5183B MXG and N5173B EXG. The MXG has phase noise of less than -124 dBc/Hz (at 10 GHz, 10 kHz offset). The EXG offers +20 dBm at 20 GHz and low harmonics of <-55 dBc to characterize broadband microwave components, such as filters and amplifiers. The generator also supports continuous-wave (CW) blocking for receiver testing or basic local-oscillator upconversion for point-to-point microwave backhaul links.

Engine fuel pump bushings

Metallized Carbon Corp.’s Metcar carbon-graphite bushings offer advantages over traditional metals for use in gear pumps that pump aviation fuel for aircraft engines. The carbon-graphite bushings are used to support both the drive gear shaft and the idler gear shaft. The bushings are preferred for this application because they can use aviation fuel as the bushing lubricant. The bushings are self-lubricating—they can run dry for short periods of time without catastrophic pump failure or significant wear. In addition, they are dimensionally stable, which permits close bushing-to-shaft running clearances. More detail at http://articles.sae.org/12700.

RS-232 Serial Adapter

ACCES I/O Products, Inc. (San Diego, CA) has released a new USB serial interface board—the ANDROID-232. Users can now control legacy RS-232 devices directly from modern Android devices. The ANDROID-232 uses the Android Open Accessory protocol to convince an Android device that its onboard USB port (normally limited to USB "slave" or "OTG" modes) is actually an RS-232 port. This two way data port allows external hardware to control the Android unit or for the Android unit to control external hardware. Serial data up to 921.6kbps is supported (a max of 115.2kbps without flow control). Onboard circuitry will provide power to charge your Android device while connected. Multiple status and fault LEDs complete the package, and allow simple and convenient confirmation of operational state.

Power Monitoring IC

Microchip Technology Inc. (Chandler, AZ) has announced a new power monitoring IC, the MCP39F501. This device is a highly integrated, single-phase power- monitoring IC designed for real-time measurement of AC power. It includes two 24-bit delta-sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible two-wire interface. An integrated low-drift voltage reference in addition to 94.5 dB of SINAD performance on each measurement channel allows accurate designs with just 0.1% error across a 4000:1 dynamic range. Operating temperature range is from -40°C to +125°C.

Voltage Controlled Oscillator

Crystek's (Fort Meyers, FL) CVCO55CC-3850-3850 VCO (Voltage Controlled Oscillator) operates at 3850 MHz with a control voltage range of 0.5V~4.5V. This VCO features a typical phase noise of -110 dBc/Hz @ 10KHz offset and has excellent linearity. Output power is typically +7 dBm. Engineered and manufactured in the USA, the model CVCO55CC-3850-3850 is packaged in the industry-standard 0.5-in. x 0.5-in. SMD package. Input voltage is 8V, with a max. current consumption of 35 mA. Pulling and Pushing are minimized to 1 MHz and 0.2 MHz/V, respectively. Second harmonic suppression is -15 dBc typical.

USB Thermocouple Power Sensors

Agilent Technologies Inc. (Santa Clara, CA) has announced the addition of two new models to its U8480 Series USB thermocouple power sensors. The U8480 Series now includes an expanded frequency range to 67 GHz and a measurement speed of 900 readings/second. The U8480 Series’ real-time measurement uncertainty feature, the first of its kind in the industry, significantly reduces overall test time by removing the need for time-consuming manual measurement uncertainty (MU) calculations. Users can now compute MU in real time and at any given point. The feature also allows them to display power measurements and their MU simultaneously.
