CALCulate<1|2>:MARKer<1 to 4>:FUNCtion:FPEaks:Y?
This query reads out the list of X values of the maxima found. The number of available values can be
queried with CALC:MARK:FUNC:FPEaks:COUNt?.
With sort mode X, the X values are in increasing order; with sort mode Y the order corresponds to
the decreasing order of the Y values.
Example: "CALC:MARK:FUNC:FPE:SORT Y"'sets the sort mode to decreasing y values
"CALC:MARK:FUNC:FPE 3"'searches the 3 highest maxima for trace 1
"CALC:MARK:FUNC:FPE:COUN?"'queries the number of maxima found
"CALC:MARK:FUNC:FPE:Y?"'queries the levels of the maxima found.
Return value:
"-37.5,-58.3,-59.6"'level in decreasing order

CALCulate<1|2>:MARKer<1 to 4>:FUNCtion:FPEaks:SORT X | Y
This command sets the sort mode for the search for maxima:
X the maxima are sorted in the list of responses according to increasing X values
Y the maxima are sorted in the list of responses according to decreasing Y values
Example: "CALC:MARK:FUNC:FPE:SORT Y"'sets the sort mode to decreasing y values

CALCulate<1|2>:MARKer<1 to 4>:FUNCtion:NDBDown <numeric_value>
This command defines the level spacing of the two delta markers to the right and left of marker 1 in
the selected measurement window. Marker 1 is always used as the reference marker. The numeric
suffix <1 to 4> is irrelevant for this command.
The temporary markers T1 and T2 are positioned by n dB below the active reference marker. The
frequency spacing of these markers can be queried with CALCulate:MARKer:FUNCtion:
NDBDown:RESult?.
Example: "CALC:MARK:FUNC:NDBD 3dB" 'Sets the level spacing in screen A to 3 dB.
Characteristics: *RST value: 6dB
SCPI: device-specific
Mode: A
CALCulate<1|2>:MARKer<1 to 4>:FUNCtion:NDBDown:STATe ON | OFF
This command switches the "N dB Down" function on or off in the selected measurement window.
Marker 1 is activated first, if necessary. The numeric suffix <1 to 4> is irrelevant for this command.
Example: "CALC:MARK:FUNC:NDBD:STAT ON" 'Switches on the N-dB-down function in
'screen A.
Characteristics: *RST value: OFF
