Aeroflex announces modular RF test platform for wireless applications
The new PXI test platform operates up to 6 GHz and is easily configured for cellular, wireless data, RFIC and general purpose wireless test applications
The configurable RF measurement system encompasses three powerful new additions:
New PXI 3000 Series hardware modules, PXI Studio software with new measurement
plug-ins, and a new PXI instrument chassis to tie it all together.
These latest additions to the Aeroflex 3000 Series modular RF test platform are available for delivery beginning in October 2007.

"Testing SIP aware routers"
Are SIP and NAT compatible? Unfortunately, no. While some SIP clients attempt to detect NAT and work around it, many existing SIP applications do not work correctly with NAT. To make matters worse, most SIP aware routers are not compatible with SIP clients using STUN techniques. To work
gracefully with SIP, a CPE router needs to be SIP aware. This document discusses the importance of testing SIP aware CPE routers using the CDRouter test solution as part of an over-all Voice over IP test strategy.

"Communications-Protocol Testing: Balancing Technology, Planning, and Compliance"
This article talks about testing communication protocols from the perspective of engineering high quality medical devices. The authors site compliance challenges, such as FDA compliance guidelines for software validation, planning, and technology challanges. "Communications interfaces in medical devices are notorious for their ability to defy traditional manual test efforts for exposing communication software defects." they conclude. "The investment in proper testing communications protocols is significant, but so too are the benefits. It's far less expensive to spend the money up front than to have to fix defects in malfunctioning devices that are already in use in clinical settings."
