You can use this functionality to track a drifting source during a phase noise measurement. Delta marker 
2, which shows the phase noise measurement result, retains the delta frequency value. Therefore the 
results of phase noise measurement with a specified offset remain valid.
When marker 2 reaches the limit of the span, the delta marker value is automatically adjusted to be 
within the span. In such cases, select a wider span.
The query returns the current state of this setting.
CALCulate<1|2>:DELTamarker<1...4>:FUNCtion:PNOise:RESult?
Queries the result of a phase noise measurement. If required, the measurement is switched on.
CALCulate:LIMit Subsystem
The CALCulate:LIMit subsystem includes the limit lines and limit checks. Limit lines may be defined as 
upper or lower. The limit line Y-values correspond to the X-axis values. The number of x and y values 
must be identical.
X Series Analyzers support up to 6 active limit lines at the same time.
CALCulate<1|2>:LIMit<1...6>:ACTive?
Queries the names of all active limit lines. For this command, all the numeric suffixes are ignored.
The return values are sorted alphabetically. If there are no active limit lines, an empty string is returned.
