Revision B
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 85 TO 264 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.
2.3.2 Front Panel Display
The 240L 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)
