Chapter 2 Operation
2.1 INTRODUCTION
The 1020L RF amplifier is used to amplify the RF level of signal sources in the 10
KHz to 5 MHz range. No tuning or any other form of adjustment is required.
The 1020L produces rated power output at its output connector, regardless of
load impedance. Any power reflected due to output load mismatch is absorbed in
the amplifier. Therefore, although the output impedance is 50 ohms (maximum
VSWR: 2:1), the amplifier will work into any load impedance.
2.2 RACK INSTALLATION
This unit is 3U high, 16.5
” width. With the handles removed it will fit into a
standard rack.
2.2.1 Mains Voltage
The unit accommodates AC line voltages from 100 TO 240 VAC 47
– 63 Hz
2.3 OPERATION
A line cord is supplied to form a connection between the mains supply and the
rear of the unit. Plug this into AC input at the rear of the unit and the AC mains
outlet.
2.3.1 Proceed as follows:
(i)
Ensure that there is at least 3” or 7.5 cm clearance at the rear of the
unit for air flow.
(ii)
Ensure RF input voltage is not excessive
a. The 1 V rms indicated maximum input voltage is 5 times the level of
the input signal required to achieve maximum output. Input voltages
in excess of 2 volts peak may permanently damage the instrument.
(iii)
Connect the output via a 50 ohm coaxial lead and BNC plug to the
load.
(iv)
Connect the input signal via a 50 ohm coaxial lead and BNC plug to
the input connector.
