Design, Verification, Troubleshooting and Maintenance of secondary surveillance radar (e.g. IFF-based radar) has never been more demanding. Proper design and operation of SSR systems can literally mean the difference between life and death. To reduce the possibility of a catastrophic event, federal aviation safety standards, such as those defined by the US Federal Aviation Administration, require transponders to undergo periodic maintenance and calibration. As a result, engineers and technicians have a need for the best analysis tools available whenever and wherever required. In addition, they want to be certain of the measurements they make. All this needs to be done in less time with less money.
