DISPlay:WINDow<Wnd>:TRACe<WndTr>:Y[:SCALe]:RPOSition
<numeric_value>
Sets the point on the y-axis to be used as the reference position as a percentage of the length of the y-
axis. The reference position is the point on the y-axis which should equal the RLEVel.
<Wnd> Number of an existing diagram area (defined by means of
DISPlay:WINDow<Wnd>:STATe ON
).
<WndTr> Existing trace number, assigned by means of
DISPlay:WINDow<Wnd>:TRACe<WndTr>:FEED
.
<numeric_value> Value of the reference position in percent. The top of the y-axis is
defined to have a reference position of 100%, while the bottom of
the y-axis is defined to have a reference position of 0%.
Range [def. unit] 0 to 100 [PCT].
*RST value 80 PCT.
SCPI, Command
Types Confirmed, with query.
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 and a trace named Ch4Tr1 to measure the input
reflection coefficient S11.
DISP:WIND2:STAT ON
Create diagram area no. 2.
DISP:WIND2:TRAC9:FEED 'CH4TR1'
Display the generated trace in diagram area no. 2, assigning the
trace number 9 to it.
DISP:WIND2:TRAC9:Y:RPOS 50
Set the reference position to the center of the diagram area.
Units for DISPlay... Commands
The DISPlay... subsystem contains commands to define particular points in the diagram, e.g. to set the
scale or a reference value. This requires the entry of a numeric value and a physical unit, depending on
the parameter type displayed. The following table lists the physical units accepted by the analyzer.
