2. OPERATING INSTRUCTIONS
2.1 GENERAL
Operation of the Model 2.5U1000 broadband amplifier is quite simple. The input signal, whether swept of 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 marked 0, 1. In the event of a unit malfunction,
protection is provided by fusing located at the rear of the unit. 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 2.5U1000
will provide 100% of rated power without
foldback into a mismatched load. The amplifier will operate without
damage or oscillation with any magnitude and phase of source and
load impedance
.
It also has been designed to withstand, without damage,
RF input power up to twenty (2) times its rated input of 1mW: However,
signal levels higher than 20 mW or transients with high peak voltages can
damage the amplifier. Also, accidental connection of the 2.5U1000 output
to the input cause oscillation which will permanently damage the input
transistor.
