Design, verification, troubleshooting and maintenance of radars has never been more demanding. Proper design and operation is critical to the safety and security of aviation. To reduce the possibility of a catastrophic event, aviation safety standards 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.
