IFI Instruments T31-250 TWT Amplifier, 1 - 3 GHz, 250W

The IFI T31-250 RF Microwave TWT (traveling Wave Tube) Amplifier provides outstanding RF performance. The IFI T31-250 Amplifier incorporate the latest features with respect to control and monitoring. The amplifier is a field proven and reliable amplifier, that offers unsurpassed performance as the best in the industry.  

The IFI T31-250 features operational safety and is easy to use. It includes a full complement of RF and hardware protection systems, including high VSWR, over-cur and voltage protection as well as redundant thermal and airflow sensors to prevent the TWT amplifier from overheating. In addition, the T31-250 TWT amplifier includes a modern interface thatis intuitive and simple to use. The modular construction and design minimizes internally produced EMI signal leakage and provides easy access for field service and rapid turnaround at depot level repair facilities.

The backlit LCD screen shows forward/reverse power indication, system status and self-diagnostic information. All the high power TWT amplifier operating parameters are simultaneously available in the amplifier front panel display as well as over the remote bus. Selection switches allow you to switch the amplifier to the desired mode of operation for local control if the unit is not being operated remotely.

For computer automation both an RS-232 and IEEE-488 interface are included.
