1.4 Selecting the input symbol rate
A 1236
27.500 MS/s
Outp. S21
8 MHz
Main menu
The input symbol rate is selected using the "<" and ">" buttons.
The input symbol rate can be adjusted continuously from 2.0 MS/s to 45 MS/s (DVB-S) or 2.0 MS/s to 30 MS/s (DVB-S2) in 0.1 MS/s
steps using the "+" and "-" buttons.
The digits can also be entered individually to an accuracy of 0.001 MS/s:
• Press the "Change setting mode" button
• The fi rst digit fl ashes and can be input directly using the numeric pad on the keyboard
• After the fi rst digit has been input, the second fl ashes, and so on
• To make a correction, press the "Back" button to skip one place to the left
• After the last digit has been set, press the "Change setting mode" button
Note: The code rate (e.g. 3/4) is automatically determined once the channel unit has locked on to the set transponder.
If an exclamation mark "!" is indicated next to the output modulation stage (e.g. QAM64), the output data rate
must be increased to ensure correct functioning. The output data rate rises with an increasing QAM stage,
higher code rate and decreasing guard interval. For more information on how the output data rate depends
on the COFDM parameters see Table 1 in Chapter 4.1.
1.5 Selecting output channel or output frequency
The output channel unit is selected using the "<" and ">" buttons.
You can use the "+" and "-" buttons to adjust the output channel from 48 to 96 MHz and from 114 to 858 MHz in 7 or 8 MHz increments.
