The 1140L is an all solid state power amplifier operating over the
range of 9 kHz to 250 kHz with a flat gain of 50 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 1140L without fear
of damage or oscillation. The 1140L 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 1140L (forward power) and the power absorbed by
the load (load power).
