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.
1.6 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 channel from 48 to 96 MHz and 114 to 858 MHz in 8 MHz increments
