Information
                                    The ENI Model 3100LA is an all solid state amplifier which
has a flat frequency response from
2 50kHz to 150MKz. it provides up to 100W of linear power
with low harmonic and intermodulation distortion. Gain is
55dB nominal, with variation of less
than +_1.5dB over the entire
frequency range. Input and output impedance are SOohms and
the unit may be driven to full power output by most RF
synthesizers, signal generators and swept^signal sources.
The ENI Model 3100LA will deliver its rated power output
into any load impedance, regardless of match. Built-in
protection circuitry will absorb the power reflected from a
mismatched load without causing failure or oscillation.
Output RF voltage is displayed on the front panel meter. The
Model 3100LA is packaged for bench mounting and is shipped
with rack
mounting adapters. Its integral power supply and cooling
operate from a 100/ 107.5/ 1150/ 120 or 200/ 125/ 230/
240VAC 50/60HZ main supply.
The Model 3100LA will raise the power level of signal
sources and generators without requiring tuning or
bandswitching. The Class A linear circuitry will amplify
signals of AM, FM, SSB, TV and complex modulations limited
only by their peak input and bandwidth, with minimum distortion.
