IFI TWT (CW) SERIES AMPLIFIERS

The TWT Amplifier (TWTA) monitors and transfers the power supply operating voltages and
currents to a Front Panel Display. This aids the user in troubleshooting in the event of a failure.
The TWTA indicates on the display where the fault has occurred.

Amplifiers are supplied with an AC line cord to accommodate the power source; an
operation & maintenance manual; and amplifier performance test data.

The Front Panel is standard for RF Connectors and RF Sample Port. If this is not

convenient, please advise the location at the time of order. We will be happy to serve you.
Thank you!

*GPIB IEEE-488 Remote Control is standard.

If this is not convenient, please review & advise the GPIB option at the time of order. These
other available options are at no charge. Thank you!
