The 1140LA is an all solid state power amplifier operating over the range of 9 kHz to 250 kHz with a flat gain of 55 dB. Its 50 ohm input is compatible with any laboratory signal generator, function generator, or integrated circuit oscillator. Any load impedance (from an open to a short circuit) may be connected to the output of the 1140LA without fear of damage or oscillation. The 1140LA delivers maximum power transfer to a 50 ohm load impedance, however, any load impedance between 2 and 800 ohms can be driven by connecting a matching transformer between the output and the load. A built-in true average power meter measures both the power leaving the 1140LA (forward power) and the power absorbed by the load (load power).
