The ENI 1040L Power Amplifier is an all solid-state power amplifier that operates over the frequency range of 10 kHz to 500 kHz with a gain of 55dB.
Its 50 ohms input is compatible with any laboratory signal generator, function generator or integrated circuit oscillator. Will operate with any load impedance (from open to short) without damage or oscillation! Output power from zero to more than 400 W is continuously adjustable by varying the amplitude of the low level input.
A built-in true average power meter measures both the power leaving (forward power) and the power absorbed by the load (load power).
