Abstract :
A dual channel downconverter (DCD) technique was developed for measuring pulsed TWT phase and noise that reduces test time, offers ease of installation in TWT test sets, and is low-cost, supportable, stable, and accurate. Phase similarity measurements have shown excellent correlation with phase bridge measurements. The stability of DCD phase measurements have been demonstrated. A low intrapulse noise floor was able to be measured on this DCD measurement system.
