<reference>
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.
'<trace_name>'
Optional string parameter for the trace name, e.g. 'Trc4'. If this optional
parameter is present, both numeric suffixes are ignored (trace names must be
unique across different channels and windows).
*RST value –
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
or: DISP:WIND2:TRAC:Y:RPOS 50, 'CH4TR1'
Set the reference position to the center of the diagram area.
DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:Y[:SCALe]:TOP <upper_value>[,
'<trace_name>']
Sets the upper (maximum) edge of the diagram area <Wnd>.
<Wnd>
Number of an existing diagram area (defined by means of
DISPlay:WINDow<Wnd>:STATe ON). This suffix is ignored if the optional
<trace_name> parameter is used.
<WndTr>
Existing trace number, assigned by means of
DISPlay:WINDow<Wnd>:TRACe<WndTr>:FEED. This suffix is ignored if the
optional <trace_name> parameter is used.
<upper_value>
Value and unit for the upper diagram edge.
Range [def. unit]
Range and unit depend on the measured quantity, see Units for DISPlay...
Commands.
*RST value
Depending on the measured quantity. The default upper edge for a dB Mag
diagram is +20 dB.
'<trace_name>'
Optional string parameter for the trace name, e.g. 'Trc4'. If this optional
parameter is present, both numeric suffixes are ignored (trace names must be
unique across different channels and windows).
*RST value –
SCPI, Command
