Key Features
- Power and Performance:
- Delivers a minimum output of 35 watts of RF power in conjunction with a sweep generator.
- User-Friendly Operation:
- Front panel gain control for effortless output level adjustments.
- Integrated RF input leveling circuit to prevent overdrive and ensure controlled amplification in varying input conditions.
- Advanced Protection Features:
- Over-temperature protection that deactivates DC voltage to RF amplifier stages during cooling blockages or fan failures.
- Digital display for monitoring operational status and fault conditions, including indications for over-temperature and power supply issues.
- Versatile Control Options:
- Equipped with digital control for smooth local and remote operation.
- Control system based on a 16-bit RISC microcontroller that manages the amplifier’s primary functions and interprets commands through a dedicated 8-bit remote interface board.
- Comprehensive control options, including IEEE-488 (GPIB) and RS-232 interfaces for full command access to all amplifier functions.
- Multi-Functional Utility:
- Can be utilized as a standalone device or as a sub-amplifier in higher power systems, with adjustable rear panel RF output configuration for flexibility.
