An integral part of Cobham Defense Electronic Systems' state-of-the-art manufacturing facilities are the extensive on-site testing capabilities. Having the ability to perform the electrical, mechanical and environmental tests on-site give the Cobham Defense Electronic Systems companies greater control over the manufacturing process. Some of the in-house testing capabilities include:

• High power pulse testing (430 MHz - 33.2 GHz)
• High power CW testing (1000 W CW, and 10 KW peak at 0-5% duty cycles)
• Temperature cycling (-65°C to +125°C)
• Encoder testing
• Antenna radiation pattern and gain
• Radar cross section
• Simultaneous high power, high altitude and temperature
• Anechoic chambers
• Near field ranges
• Far field ranges
• Vibration
• Gross leak
• Plasma
