Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 299
:FUNCtion<N>:FFT:REFerence
Command :FUNCtion<N>:FFT:REFerence {DISPlay | TRIGger}
The :FUNCtion<N>:FFT:REFerence command sets the reference point for
calculating the FFT phase function.
<N> An integer, 1 - 4, representing the selected function.
Example This example sets the reference point to DISPlay.
myScope.WriteString ":FUNCTION1:FFT:REFERENCE DISPLAY"
Query :FUNCtion<N>:FFT:REFerence?
The :FUNCtion<N>:FFT:REFerence? query returns the currently selected
reference point for the FFT phase function.
Returned Format
[:FUNCtion<N>:FFT:REFerence] {DISPlay | TRIGger}<NL>
Example This example places the current state of the function 1 FFT reference
point in the string variable, strREF, then prints the contents of the
variable to the computer's screen.
Dim strREF As String
myScope.WriteString ":FUNCTION1:FFT:REFERENCE?"
strREF = myScope.ReadString
Debug.Print strREF
