Informationen:
                                    The ENI Mode! 1140LA is an all solid-state amplifier that
has a flat frequency response from 9 kHz to 250 MHz with a
gain of 55 dB. Its 50Ω input is compatible with any
laboratory signal generator, function generator or
integrated circuit oscillator. Input and output impedances
are 50Ω and the unit may be driven to full power output by
most RF synthesizers, signal generators and swept signal
sources. Output power from zero to more than 1500 W is
continuously adjustable by varying the amplitude of the
low-level input. 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 unit provides
maximum power transfer to a 50Ω load impedance; however, any
load impedance between 40 to 60Ω can be driven with no
reduction in power output. Gain is 55 dB nominal with
variation of less than ±1.0 dB over the entire frequency
range. It provides at least 600 W of saturated power from 4
kHz to 400 kHz.
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). Extraordinary meter accuracy is
provided by a unique computer circuit in the output. By
adjusting the tuning (or frequency of the load) and
observing the increase in load power, optimum match can be
readily achieved.
Complete with built-in power supply and cooling system, the
1140LA will operate from any 115 VAC line with a 35 A capacity.
The 1140LA will deliver its rated power output into any load
impedance regardless of match (up to 400 W of reflected
power). Output RF voltage is displayed on the front panel
meter. The 1140LA is packaged for bench mounting and is
shipped with rack-mounting adaptors. The 1140LA will raise
the power level of signal sources and generators without
requiring tuning or bandswitching.
