TSN (Hex)
"TSN (Hex)" requires "CM Mode > CCM/ACM" and "Annex M > On".
Sets the input stream identifier or the time slice number (TSN). This number is used for
identification. Each time slice uses a unique TSN.
for time slice
1. Configure the other time slices in the "TSL 2 - x"
tab, see
Chapter 3.3.3, "IS 2 - x Settings"
If "CM Mode > VCM", all input streams use the same number and are grouped under
time slice
1. You can set the
Remote command:
[:SOURce<hw>]:BB:DVBS2:TSL<st>:IS<ch>:TSN
ISI (Hex)
Requires "CM Mode > VCM".
Sets the input stream identifier (ISI).
All input streams use the same number and are grouped under time slice
1.
If "CM Mode > CCM/ACM", configure the
for time slice
1, see
Configure the other time slices in the "TSL 2 - x" tab, see
Remote command:
[:SOURce<hw>]:BB:DVBS2:TSL<st>:IS<ch>:ISI
Num Symbols
Requires "Annex M > On".
Displays the information about the number of symbols.
Note:
The setting for time slice
1 is displayed on this side tab, the settings for all time
slices
> 1 are available on the "TSL 2 - x" side tab. See
Remote command:
[:SOURce<hw>]:BB:DVBS2:TSL<st>:IS<ch>:NSYM?
Mod. Cod.
Defines the modulation coding, a combined setting of constellation and code rate.
Note:
The setting for time slice
1 is displayed on this side tab, the settings for all time
slices
> 1 are available on the "TSL 2 - x" side tab. See
Changes of the modulation coding affect the maximum useful data rate (see
on page 19): The code rate defines the puncturing rate of the convo-
lutional coder. Since the convolutional coder inserts redundancy into the symbol
stream, the code rate influences the max. useful data rate at a given symbol rate.
