does not affect the value of PDIVision. The trace can be referenced either by its number <WndTr> or by
its name <trace_name>.
<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.
<level>
Value and unit for the reference level (or reference value, if the trace does not
show a level).
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 reference level for an S-
parameter displayed in a
dB Mag
diagram is 0 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
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:RLEV -10
or:
DISP:WIND2:TRAC:Y:RLEV -10, 'CH4TR1'
Change the reference level to –10 dB.
DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:Y[:SCALe]:RPOSition <reference>[,
'<trace_name>']
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
). 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.
