Current Channel
The current channel menu allows viewing/changing the tuned RF carrier settings.
Preset
Allows selection of a channel defined in the settings table, the permanent source, or last commanded. The settings table is a
list of channels (with all tuning parameters). If any exist, they will be listed here. The permanent source is changed when the
iPump562 is tuned to and locked to a carrier. The last commanded is the channel that unit was last tuned to, even though it
may not have locked to it.
Modulation
Allows selection of modulation type. Choices are QPSK, S2QPSK, and S28PSK.
FEC Ratio
Allows selection of FEC inner code rate. Choices are dependent upon modulation selected.
Frequency
Allows editing of the RF carrier frequency. This frequency value must be a valid value based on the LNB LO setting (C band,
KU band, etc.). The LNB LO frequency should be correctly set before setting this value. The iPump562 receives L band
frequencies in the range of 950 MHz to 2150 MHz. The LNB will down convert the actual transmitted RF carrier frequency to
L band. This entry is the actual transmitted RF carrier frequency.
Data Rate
Allows editing of the data rate of the modulated signal in Mb/s to a resolution of 1 Kb/s.
Symbol Rate
Displays the calculated symbol rate based on Modulation, FEC Ratio. Data Rate, and Pilots (in the case of DVB-S2 carriers).
In the case of DVB-S2 carriers, the iPump562 requires that pilots be inserted in the transmission when the symbol rate is less
than or equal to 10 MS/s and pilots not be inserted when the symbol rate is greater than 10MS/s.
