Item Description
RF:MEASUre:ACPR:LA3DB?
This query measures a ratio between the third lower side channel and the Main c hannel when
performing ACPR measurements using a frequency domain trace. The power in the adjacent
channel is equivalent to the power in the main channel (dBm) added to the power ratio (dB) of
the adjacent channel. (The RF measurement type must be set to ACPR using the command
RF:MEASUre:TYPe.)
RF:MEASUre:ACPR:POWer? This query returns the measure of the total RF power in the M ain channel when performing
ACPR measurements using a frequency domain trace. It uses the units that have been
selected with the command RF:UNIts.
RF:MEASUre:ACPR:UA1DB? This query measures a ratio between the first upper side channel and the Main channel when
performing ACPR measurements using a frequency domain trace. The power in the adjacent
channel is equivalent to the power in the main channel (dBm) added to the power ratio (dB) of
the adjacent channel. (The RF measurement type must be set to ACPR using the command
RF:MEASUre:TYPe.)
RF:MEASUre:ACPR:UA2DB?
This query measures a ratio between the second upper side channel and the Main channel
when performing ACPR m easurements using a frequency domain trace. T he power in the
adjacent channel is equivalent to the power in the m ain channel (dBm) added to the power
ratio (dB) of the adjacent channel. (The RF measurement type must be set to ACPR using
the command RF:MEASUre:TYPe.)
RF:MEASUre:ACPR:UA3DB?
This query measures a ratio between the third upper side channel and the Main channel
when performing ACPR m easurements using a frequency domain trace. The power in the
adjacent channel is equivalent to the power in the m ain channel (dBm) added to the power
ratio (dB) of the adjacent channel. (The RF measurement type must be set to ACPR using
the command RF:MEASUre:TYPe.)
RF:MEASUre:CP:CHANBW This command specifies the channel bandwidth to use when the R F measurement type has
been set to Channel Power (CP) using the command RF:MEASUre:TYPe.
RF:MEASUre:CP:POWer?
This query returns the total channel power within the displayed channel bandwidth, when the
RF measurement type has been set to CP (using the command RF:MEASUre:TYPe).
RF:MEASUre:OBW:CHANBW This command specifies the Analysis Bandwidth to use, when the measurement type has been
set to OBW (using the command RF:MEASUre:TYPe). Note that the span automatically
increases or decreases to be 10% more than the Analysis Bandwidth (providing some room
around the signal of interest).
RF:MEASUre:OBW:LOWERFreq? This query returns the lower frequency threshold (on the display, the white line to the left
bracketing OBW power). The RF measurement type must be set to OBW using the command
RF:MEASUre:TYPe.
RF:MEASUre:OBW:
PERCENTdown
This command specifies the percentage of total power within the Analysis Bandwidth (the O B W
power) such that half of the remaining power will be below the OBW:LOWERFreq level and the
other half of the remaining power will be above the OB W:UPPERFreq level.
RF:MEASUre:OBW:POWer?
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:MEASUre:TYPe).
RF:MEASUre:OBW:UPPERFreq? This query returns the upper frequency threshhold (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:MEASUre:TYPe.
RF:MEASUre:TYPe This command specifies the RF m easurement type: Channel Power, Adjacent Channel Power
Ratio, Occupied B andwidth, or none.
