The RF 6000 from Laplace Instruments is a synthesizer for immunity testing that operates from 80 MHz to 6 GHz. It features PC-controlled signal sources meeting IEC61000-4-3 requirements. Utilizing Windows RFSynth3 control software with a USB interface and a field probe input for automatic level control, it provides a CW output of -60 dBm to 0 dBm with a frequency step of 0.25% to 9%. 

The synthesizer-generated signal can be fed to the cell or antenna via a fixed gain power amplifier. This test system supports real-time feedback or pre-programmed level modes of operation. It generates the required signals and controls the amplitude to produce the necessary field strength. The system interfaces a simple EUT status signal back to the PC and generates a 'prompt' signal to the EUT under PC control. This test system is suitable for use with any power amplifier and antenna/cell/chamber combination.
