Types of Detection
[:SENSe]:DETector:TRACe[1]|2|3|4
[FUNCtion]

[:SENSe]:DETector:TRACe[1]|2|3|4
[FUNCtion]?
This command specifies the detection mode. For
each trace interval (bucket), average detection
displays the average of all the samples within the
interval. The averaging can be done using two
methods:
• The power method (RMS)
• The video method (Y Axis Units)
The method is controlled by the TRACE, Detector.
FREQuency Subsection

[:SENSe]:FREQuency:CENTer?
This command sets the center frequency.
Center Frequency Step Size Automatic
[:SENSe]:FREQuency:CENTer:STEP:AUTO
OFF|ON|0|1
[:SENSe]:FREQuency:CENTer:STEP:AUTO?
This command specifies whether the step size is
set automatically based on the span.
