Examples
RF:MEASUre:OB
W:PERCENTdown
80 sets the OBW upper and lower frequencies
such that 80% of the total power is contained within these two frequencies, with
20% remaining (10% on either side of these bounding frequencies).
RF:MEASUre:OBW:PERCENTdown? might return 85.0000, indicating that 85% of
the total power has been set to fit within the occupied bandwidth.
RF:MEASUre
:OBW:POWer? (Query Only)
This query returns the total channel power within the occupied bandwidth,
when the RF measurement type has been set to OBW (using the command
RF:MEASU
re:TYPe). The units are user-set (with the command RF:UNIts).
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.

RF:MEASUre:OBW:LOWERFreq?, RF:MEASUre:OBW:UPPERFreq?
Examples
RF:MEASUre:OBW:POWer? might return –26.1607, indicating that the total
channel power within the occupied bandwidth is 26.1607 user-set units.
RF:MEASUre:OBW:UPPERFr
eq? (Query Only)
This query returns the upper frequency threshold (on the display, the white line to
the right bracketing OBW power). The RF measurement type must be set to OBW
using the command RF:ME
ASUre:TYPe. This frequency will locate the position
where (100% — OBW:PERCENTdown)/2 power is above this frequency.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.
