time. This marker can be used to monitor the effects of the selected trigger, e.g. trigger
causing restarts of the signal generation.
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....
