“Control by:”
For the “MCPAs’ MUTE” and “Reflected Power Alarm Reset” commands, the
user can set the preferred control method by choosing Software or Hardware
in the “
Control by”
field.
a.
If the user chooses hardware control, the controller will respond to the
opto-isolated inputs located in the DB-25 to screw terminals break-out
board and the software commands for these two parameters will have
no effect.
When “Control by Hardware” is selected the MCPA is automatically
unmuted unless the corresponding opto-isolated input is energized.
b.
On the other hand, if the user chooses software control, the controller
will respond to these software commands instead of to the opto-
isolated inputs.
Maximum Desired Output Level per filter(dBm):
Allows the configuration of the output level such as the maximum gain per
path will be less than or equal to 120dB.
The specified value cannot be modified in case the maximum gain would be
greater or equal than 120dB.
The Maximum Desired Output Level is the user setting or goal set point for the
RF Output power level per filter window, subject to the following two
constraints:
1.
Maximum Gain of 120dB:
The maximum gain for any filter window may not exceed 120dB. Due
to the Automatic Gain Control (AGC) function, the system calculates
the Gain starting at the minimum signal level able to be received,
which is defined by the Rx Threshold (Squelch) setting. Signals coming
in at that threshold level will be amplified a maximum of 120 dB.
Therefore:
