Scaling:
Voltage monitor into 50 Ohms 1V = 50 V at amplifier output
Current monitor into 50 Ohms 1V = 1 A at amplifier output
Note: Signal processing of these monitors can provide information such as
VSWR, load impedance, phase etc., as the phase relationship between V and A
is maintained.
2.2 RACK INSTALLATION
This unit is 2U high, 19
” width.
2.2.1 Input Voltage
The unit requires 110
– 240 VAC 50/60 Hz
2.3 OPERATION
The AC input is an IEC 60320 C20 receptacle. A line cord is supplied to provide
a connection between the supply and the rear of the unit.
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)
Connect the output via a 50 ohm coaxial lead and N connector to the
load.
(iii)
Connect the AC supply to the rear of the unit.
(iv)
Connect the input signal via a 50 ohm coaxial lead and N connector to
the input connector.
Chapter 3 Technical Description
3.1 GENERAL DESCRIPTION
The 1000S04 is designed to amplify signals by 60 dB in the frequency band of 20
to 400 KHz. The signal from the front panel RF connector is fed into the input of
the pre-amplifier module. The pre-amplifier provides voltage gain and signal
conditioning to prevent overdrive of the pulse width modulators. The signal from
the output of the pre-amplifier is fed into the pulse width modulators (PWM) that
