Revision A
2.2 RACK INSTALLATION
This unit is 35.5 U high, 24
” width, 30” Length.
2.2.1 Mains Voltage
The unit runs of 208 3 phase VAC 47
– 63 Hz. 30 Amps max
2.3 OPERATION
A fixed line cord is supplied to form a connection between the mains supply and
the rear of the unit. The plug is L14-30P 3 pole / 4 wire.
2.3.1 Proceed as follows:
(i)
Ensure that there is at least 24” or 60 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.
b. The unit should not be driven at an input of over 1 dBm for a period
of greater than one minute
(iii)
Connect the output via a 50 ohm coaxial lead and N plug to the load.
(iv)
Connect the input signal via a 50 ohm coaxial lead and N plug to the
input connector.
2.3.2 Front Panel Display
The A1000 front panel has a passive LCD display designed for simplicity and
ease of use. During initialization, the LCD shows the software revision. After the
amplifier is initialized, the LCD indicates Forward Power, Reflected Power, and
amplifier status (see figure 2.1).
Pf:___W Pr:___W
Status:________
Figure 2.1 : Front Panel Display
Where Pf refers to forward power, Pr refers to reverse power, and Status
indicates “OK” unless there is a fault condition, such as:
Overheat (heat-sink temperature is too high for reliable operation)
