2. OPERATING INSTRUCTIONS
2.1 GENERAL
Operation of the Model 100S1G6AB broadband amplifier is simple. The input signal, whether swept or fixed
in frequency, is fed into the jack marked INPUT and the amplifier output signal is taken from the jack labeled
OUTPUT. The unit is turned ON by activating the power switch. In the event of a unit malfunction,
protection is provided by a circuit breaker located in the AC input receptacle. A polarized, three (3) wire AC
power cord is also included with the unit to provide cabinet and chassis grounding to the power mains.
CAUTION:
The Model 100S1G6AB amplifier is not critical in regard to source and
load VSWR and will remain unconditionally stable with any magnitude
and phase of source and load VSWR. It is designed to withstand, without
damage, RF input power up to twenty (20) times its rated input of 1mW.
However, signal levels higher than 20mW or transients with high peak
voltages can damage the amplifier. Also, accidental connection of the
100S1G6AB output to the input causes oscillations which will
permanently damage the input circuitry.
CAUTION:
Although designed for overdrive and load tolerance described above,
subjecting the amplifier to these conditions simultaneously can cause
failure of the output transistor. Repeated failures of this nature will not
be covered under warranty.
The 100S1G6AB Amplifier is protected from input overdrive by an automatic level control circuit which will
limit the maximum RF level to the first gain stage of the RF Amplifier to approximately 0 dBm. NOTE: The
amplifier requires 30 minutes of warm-up time to avoid any gain or power drift.
The 100S1G6AB RF power transistors are protected from over temperature by sensing the chassis
temperature near the RF output transistors. In the event of a cooling fan failure or an airflow blockage, the DC
voltage will be removed from the RF stages, when the chassis temperature reaches approximately 70°C.
Normal operation can be resumed after the chassis temperature drops below 70° C.
