Global Status Page
The Global status page appears upon login and provides general information about
parameter settings and the modulator’s alarm status. The list of parameters will change
dynamically as the transmission mode (MFN or SFN) is changed. See Figure 8 or Figure
9 for details.
The drop down menus, located at the top of the status page, provide links to other
pages that control various parameters and alarm functions.
• Versions and Serial Numbers: Displays the software and firmware version
number for each of the main software components of the modulator.
• Transmission: Displays the Modulator Mode (Normal or CW), the SFN status
(On or OFF) as well as the MH Enable status (ON or OFF) and the Ideal Bitrate.
Additional transmission parameters, including Transmitter ID, OM_type, Stream
Maximum SFN Delay, STS Backend Delay, STS Propagation Delay, Local
DelayOffset, Net Id Pattern, Tx Id Level and Transmit Power will become
available when SFN mode is enabled.
• Field Rate Side Channel: Indicates whether a Field Rate Side channel is present
or not and displays the System Mode, Primary Communication Channel and
Active Channel.
• Input: Displays the Selected Input (A, B or Auto) and the Input Status (Locked
or Unlocked). This section also shows the input bit-rate and the status of the
reference inputs: “10MHz” and “1pps”.
• Output: Displays the status of the Mute parameter (un-muted in this case) and
the spectrum inversion (ON or OFF). It also shows whether the output is muted
or not (even though the Mute is OFF, the output might be muted as a result of an
active alarm). This section also displays the RF Output Frequency and the RF
Power Level.
• Pre-corrector: Displays the status of the Linear and non-linear pre-corrector
• Network: Displays the modulator IP addresses, gateway and the management
netmask.
• Ethernet Interface status: Indicated the status of the Ethernet connection
• User Configuration: Displays the address assigned to the RS485 port for M2M
communication.
• Digital Adaptive Precorrector: Indicates the Digital Pre-corrector Hardware
and Software revisions as well as the user configured Pre-corrector settings
(1PPS Offset, Mode, NLP/LP Selection, NLP Cycles and status). The window will
also display the Non-linear and Linear measurements including Peak to Average
Ratio, MER, Lower Shoulder, Upper Shoulder and Group Delay. The RMS
measurement is a scaling factor used to indicate the Pre-corrector input power
level. The maximum allowable value is 32,000,000.
• Alarms: Shows the number of active alarms.
