6. Installation Procedure
6.1 Introduction
This section contains the necessary informations for the installation and preliminary
checks on the PJ5000M.
6.2 Unpacking
Unpack the amplifier and before any other operation check that the amplifier hasn’t
been damaged during transport and all the controls and connectors on the front and
rear panels are in good condition.
6.3 Installation
To install the PJ5000M, it is necessary to perform the following operations:
1) With the help of Figure 2, verify that all the connections are in perfect condition.
Possible errors can damage the amplifier modules.
2) As shown in the figure above, connect a 5KW 50 Ohm dummy load to the HC5-
1's output connector with a through wattmeter in series.
3) Connect an exciter with a output power not less than 150W to the R.F. input of
the HC5-1.
4) Set the output power of the exciter to the minimum value.
5) Switch on the five PJ1000M and the exciter, and then wait until the exciter is
locked onto the operating frequency.
6) Increase gradually the output power of the exciter, verifying at the same time a
proportional increase of output power of the PJ1000M (PWR FWD of the five
amplifiers) and an increase of the output power on the meter of the hybrid
combiner with the selector on the FWD position; the output power on the meter
of the HC5-1 hybrid combiner is, apart from the instruments reading errors and
the little loss in the combiner, the sum of the output power of each amplifier.
This value can be compared with the value read on the external wattmeter.
