W:CHANBW, RF:MEASUre:OBW:POWer?,
RF:MEASUre:OBW:PERCENTdown, RF:MEASUre:OBW:LOWERFreq?
Examples
RF:MEASUre:OBW:UPPERFreq? might return 2.4000E+9, indicating that the
upper frequency threshold is 2.4000E+9 Hz. If
OBW:PERCENTdown is 80%, then
(100%-80%)/2 or 10% of the total power will be above 2.4000E+9 Hz.
RF:MEASUre:TYPe
This command specifies the RF measurement type: Channel Power, Adjacent
Channel Power Ratio, Occupied Bandwidth, or none.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.

Syntax
RF:MEASUre:TYPe {NONe|CP|ACPR|OBW}
RF:MEASUre:TYPe?
Arguments
CP — Channel Power is the total power within the bandwidth defined by the
channel width. When this measurement is active, the span is automatically set
10% wider than the channel width, and the auto detection method is set to Average.
To configure the channel width, use the command RF:MEASUre:CP:CHANBW.
To query the total power within the channel bandwidth, use the command
RF:MEASUre:CP:POWer?
ACPR — The Adjacent Channel Power Ratio returns the power in the main
channel and the ratio of channel power to main power for the upper and lower
halves of each adjacent channel. When this measurement is active, the span is
automatically set 10% larger than required to capture all channels, and theauto
detection method is set to Average. To configure the number of adjacent channels,
use the command RF:MEASUre:ACPR:ADJACENTPAIRs. To configure the
channel width, use the command RF:MEASUre:ACPR:CHANBW. To configure
the channel spacing, use the command RF:MEASUre:ACPR:CHANSPACing
OBW — Occupied Bandwidth (OBW) is the bandwidth that contains the specified
% of power within the Analysis Bandwidth. The OBW is the difference between
the Upper Frequency and the Lower Frequency. When this measurement is active,
the span is automatically set 10% larger than required to capture all channels, and
the auto detection method is set to Average. To specify the Analysis Bandwidth,
use the command RF:MEASUre:OBW:CHANBW. To specify the % of power,
use the command RF:MEASUre:OBW:PERCENTdown.
