Example:
Symbol Rate = 1 Msym/s, Divider = 2
The marker frequency is 500 kHz, corresponding to a marker period of 2 us. Each On
and Off period has a length of 1 us, corresponding to one symbol period. With a divider
of 4 (6, 8 ...), the length of each On and Off period is increased to 2 (3, 4, ...) symbol
periods.
Marker Mode Pattern
Periodic marker where each period is defined by a bit pattern with a maximum length
of 64 bits. A "1" ("0") in the pattern denotes an On (Off) signal segment with a duration
of one sample/symbol period.
Example:
In the following example, the marker signal is defined by a pattern 100100... .
Marker Mode ON/OFF Ratio
Similar to "Pulse" but with independent lengths of the On and Off periods. The length
of the periods is entered as a number of symbols/sample periods.
