USB Digital I/O Board Enables High-Speed Digital Monitoring and Control

ACCES I/O Products (San Diego, CA) offers the Model USB-IIRO-16, featuring 16 Form C (SPDT) electromechanical relays and 16 optically isolated digital inputs. The board is designed to meet the needs of industrial systems monitoring and control. The industrial I/O market commonly uses electromechanical Form C relays due to their robustness and ability to withstand unexpected surge currents, allowing for increased flexibility in switching capability. These relays also are used where small reed relays are inadequate due to their susceptibility to contact damage.

PLL/Synthesizer Includes VCO

Crystek Corporation’s (Fort Myers, FL) CPLL66 family is the company’s first foray into the PLL/Synthesizer market. Designed for digital radio equipment, fixed wireless access, satellite communications systems, base stations, personal communications systems, portable radios, and test instruments, the CPLL66 is a complete PLL/ Synthesizer that only needs an external frequency reference and supply voltages to operate the internal PLL (phase lock loop) and VCO (voltage controlled oscillator).

F-35 Antenna Measurement Program

Engineers are conducting sophisticated performance testing of F-35 Joint Strike Fighter (JSF) antennas at the AFRL Newport Research Facility, New York. Through an agreement with the F-35 Joint Program Office, engineers from Lockheed Martin and AFRL’s Rome Research Site are collaborating on the test effort. Because antenna testing is occurring early in the aircraft development cycle, the team is using a model—a full-scale F-35 replica—to measure the installed performance of the aircraft’s communications, navigation, identification, and electronic warfare antennas. The goal of this testing program is to optimize antenna performance and identify and correct antenna problems before the aircraft design is finalized and antenna system changes consequently become more difficult and expensive to incorporate.
