"Measurement Type" on page 1055 determines which type of power result is returned: Total Pwr Ref
(TPRef) or PSD Ref (PSDRef)
*For PSD results, the unit is determined by "PSD Unit" on page 1063: DBMHZ or DBMMHZ
If any result is not available, 9.91E+37 (NaN) is returned
11 Returns Marker Table data as a series of comma separated values in the following form:
<Marker Number>,<Marker Trace>,<X>,<Y>,<Reserved>,<Reserved>
Only markers that are enabled are included. <Reserved> are returned as NaN (“Not a Number”, 9.91e+37).
The data is returned in the current sort order as displayed in the Marker Table
