0orOFFindicat
es that the RF input is not clipping.
Examples
RF:CLIPPING? might return 0, indicating that the RF input is not clipping.
RF:DETECTionmethod:MODe
This command specifies whether the RF detection within the oscilloscope occurs
automatically or manually. If you set the detection method mode to MANual, you
areabletousetherelated
RF:DETECTionmethod commands to specify detection
method options for the frequency domain traces (the options are
MINUSpeak,
SAMple,
PLUSpeak and AVErage).
The detection method is the internal calculation that decimates (reduces)a
long fr
equency domain waveform down to display resolution, by dividing the
waveform into intervals and choosing a single value to represent each interval
on screen.
Conditions
MDO3000, MDO4000/B, or MDO4000C models with option SA3 or SA6 only.

Examples
RF:DETECTionmethod:MODe MANual sets the detection mode to manual.
RF:DETECTionmethod:MODe? might return AUTO, indicating that the RF
detection mode has been set to automatic.
RF:DETECTionmethod:RF_AVErage
This command specifies the detection method the oscilloscope should use when
acq
uiring an RF Average frequency domain trace.
In order to change the detection method, you must first change the detection
met
hod mode to
MANUAL using the command RF:DETECTionmethod:MODe.

Related Commands
RF:DETECTionmethod:MODe,

RF:DETECTionmethod:RF_MINHold,
RF:DETECTionmethod:RF_NORMal
Arguments
PLUSpeak — Detection method that selects the largest value in each interval.
MINUSpeak — Detection method that selects the smallest value in each interval.
SAMple — Detection method that selects the first point in each interval.
AVErage — Detection method that selects the mean value within an interval.
Examples
RF:DETECTionmethod:RF_AVErage SAM sets the detection method to sample.
RF:DETECTionmethod:RF_AVE? might return MINUSP EAK , indicating the
detection method has been set to select the smallest value in each waveform
interval.
RF:DETECTionmethod:RF_MAXHold
This command specifies the detection method the oscilloscope should use when
acquiring an RF Max Hold frequency domain trace. The Max Hold trace displays
the largest value in all acquisition history at each trace point.
In order to change the detection method, you must first change the detection
method mode to
MANUAL using the command RF:DETECTionmethod:MODe.
The detection method is the internal calculation that decimates (reduces)a
long frequency domain waveform down to display resolution, by dividing the
waveform into intervals and choosing a single value to represent each interval

Arguments
PLUSpeak — Detection method that selects the largest value in each interval.

SAMple — Detection method that selects the first point in each interval.
AVErage — Detection method that selects the mean value within an interval.
Examples
RF:DETECTionmethod:RF_MAXHold SAM sets the detection method to sample.
RF:DETECTionmethod:RF_MAXHold? might return AVERAGE, indicating the
detection method has been set to select the mean value within a wavef
orm interval.
RF:DETEC
Tionmethod:RF_MINHold
This command specifies the detection method the oscilloscope should use when
acquiring an RF Min Hold frequency domain trace. The Min Hold trace displays
the smal
lest value throughout the acquisition history at each trace point.
In order to change the detection method, you must first change the detection
method mode to
