Coax switch matrix has CANbus interface
The Model 4104 Series coaxial switching matrixes have a maximum frequency of 18 GHz and can be configured with up to four SP10T switch assemblies. The switch matrixes come with Ethernet, GPIB, serial I/O, and CANbus control interfaces. The EWEB version of the product also supports TCP/IP protocols, so you can control the matrix via the Web.

Data-acquisition card resolves 24 bits for sound and vibration measurements
The PXI-4472B is a four-channel card with 24-bit ADCs that delivers 100 dB of dynamic range and a bandwidth of 45 kHz. The board can sample four channels simultaneously and comes with built-in IEPE transducer conditioning circuits for accelerometers and microphones.

Software tests and simulates multiple protocols
CoPilot software allows you to test and analyze MIL-STD-1553, ARINC 429/575, and ARINC 708/453 avionics databuses when used with Ballard BUSBox and OmniBus interface boards. Context-sensitive menus and drag-and-drop operations speed test setup and execution, and users can view data using a number of different displays, including aircraft instruments, strip charts, and moving map displays.

EMC generator runs auto tests right out of the box
The EFT200B are pre-programmed to run a variety of standard and manufacturers' tests with a single click on the front panel. These tests can, however, be easily modified using the system software, and the unit is capable of generating frequencies and peak voltages that are higher than currently required. The generator can also be operated remotely as part of an automatic test system. Amplifier Research, Souderton, PA. 215-723-8181; www.amplifiers.com .
Catalog describes microwave-absorbing materials
A catalog from R&F Products outlines the company's line of microwave absorbing materials, including foam, thermoplastics, and die-cut elastomers. The catalog also describes custom solutions, which can aid in a wide variety of problems such as internal cavity resonances, antenna pattern shaping, and high-frequency interference.
