Travelling Wave Tube Test System
TWT Testers
Yelo has a wealth of experience in developing and customizing test systems for the Travelling Wave Tube (TWT) market. TWT testers feature specialized power supplies, measurement equipment, and comprehensive control and safety systems.
A rugged PLC is used to control all voltages and perform all monitoring functions. User interface and datalogging functions are provided by a supervisory PC that is electrically isolated from the PLC. Power Supplies are solid state with optical fibre barriers to ensure that all control/monitoring is carried out at safe voltages, and with maximum noise immunity. All safety interlocks are hardwired, and the testers are equipped with emergency shutdown features for added security.
