This section covers the following
ViaLiteHD
RF support module:
Amplifier module
o
HRA-1 single amplifier
The
ViaLiteHD
amplifier allows you to provide additional gain in your equipment chassis. The gain of the amplifier is controlled either via
manual gain control switches, SNMP (requires SNMP and web controller) or via Web GUI (requires SNMP and web controller). When under
SNMP or Web GUI control the amplifier may also use AGC. It also has an RF detector that reports power and is used for automatic gain
control.
Some units are also fitted with a DC pass through. This allows DC current to pass from the input to the output of the module, which may be
used to power external hardware via the coaxial cable.
The
ViaLiteHD
frequency source offers the following key advantages:
Small 5HP form factor
Blindmate capability
Gain control, both manual and automatic
RF power detector
