TMD Launches Modular Test Station For Travelling Wave Tubes

The PTT4100 test station introduced by TMD Technologies is designed for testing travelling wave tubes (TWTs). It provides a full test capability for a wide range of low and medium power pulse / continuous wave TWTs used in today's communications and EW systems.

Its flexible, modular design allows users to configure it to their exact requirements. Each module is self-contained and offers a full range of monitoring and display functions. Additional modules can be easily added later if users' needs change.

The comprehensive and accurate monitoring and display functions in each module make the test station ideally suited for the production testing of TWTs, while the flexibility of the modular approach is ideal for facilities where a wide range of TWTs need to be tested.

The PTT4100 consists of a 19" rack with distribution and control modules pre-installed. Anode, cathode, collector, focus electrode and grid modules can be supplied according to customer requirements. Up to four collector modules can be specified, permitting the latest generation of multiple collector Mini-TWTs to be tested.

Each module is provided with extensive monitoring, BIT and protection features to ensure long term reliability. Programmable levels for most protection parameters permit the user to select the best protection regime for each TWT under test. All modules feature minimum stored energy, fast acting trips and protection resistors to limit the energy dissipated in any TWT arcs.

The test station has been designed for ease of use and with operator safety in mind. All intermodule high voltage connections are located inside the rack behind covers. Interlocks are provided on all covers to prevent operator access to high voltages, while the TWT connections are also protected by an interlocked cover.
