R&S ESU Remote Control – Description of Commands
CALCulate Subsystem
CALCulate<1|2>:MARKer<1...4>:FUNCtion:FPEaks:SORT X | Y
This command sets the sort mode for the search for maxima:
Parameter: 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
Characteristics: *RST value: --
SCPI: device-specific
Mode: A
CALCulate<1|2>:MARKer<1...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...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
?.
If a negative value is entered than the markers are placed n dB above the active reference marker.
This is then a n dB up function which can be used for notch filter measurements:
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...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...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
SCPI: device-specific
Mode: A
