5.3.3 Power Amplifier Menu (P.A.)
This screen, consisting of several lines that may be scrolled through by using
the UP and DOWN keys, displays all the measurements associated with the RF
amplifier of the equipment:
• Voltage (VPA)
• Current (IPA)
• Efficiency
• Temperature
• Power Supply Voltage (Mains - percentage variation as compared to the nominal
voltage)
The figure below shows the complete aspect of this screenful (only two lines can
be seen at a time, use the UP and DOWN keys to scroll through it):
5.3.4 Warning threshold setting menu
As mentioned in the introduction the amplifier offers three settable warning
thresholds. Each one is compared with the level of one of the machine’s operating
parameters. The results of the comparison are available on the telemetry connector,
on the contacts of the optional external telemetry card and may be read on the
display as “O” (open, i.e. false result) or “C” (closed, i.e. real result).
Two of the settable thresholds (
P o w e r G oo d
) refer to the emitted power level
whereas the reflected power quantity ( R e fl ected War ning ) is checked for the third
one.
