Figure 13 - Inhibiting / Enabling RF
RF Inhibit Mode
In most cases Xicom XTRT series amplifiers have an internal pre-amplifier. RF is inhibited
by disabling this pre-amp. In cases where there is no pre-amp the high voltage will be
disabled for RF inhibit. RF can be inhibited from a number of sources internal and
external to the amplifier. RF Enable (converse to inhibit) is indicated by a green color of
the RF button. RF inhibit via software control will be indicated by amber color of this
button. When RF is inhibited from another source this button will be gray in color. More
details of the RF inhibit source are available on the Amplifier Tab described in the next
section of this chapter. Sources of RF inhibit are listed below.
•
RF Inhibit software controlled (internal)
•
External RF Inhibit (AUX interface connector rear panel)
•
W/G switch 1 RF inhibit (external, 1:1 configuration)
•
W/G switch 2 RF inhibit (external. 1:2 configuration)
•
W/G arc fault RF inhibit (internal)
•
Overdrive RF inhibit (internal)
