Marker mode pulse
Periodic marker with consecutive On and Off periods of equal length. The first On
period starts at the beginning of the first generated sample/symbol. The marker fre-
quency is defined by a "Divider". The frequency is derived as follows:
<Frequency> = "Symbol/Sample Rate" / "Divider", respectively
<Frequency> = "Sampling Frequency" / "Divider".
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.
