Parameters:
<RefLevel> Value and unit for the reference level (or reference value, if the
trace does not show a level). Range and unit depend on the
measured quantity, see "Units for DISPlay... commands"
on page 1099.
Default unit: NN
<TraceName> 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 win-
dows).
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 and a trace named Ch4Tr1 to measure the
input reflection coefficient S
11
.
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.
Manual operation:
See "Ref Value" on page 329
DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:Y[:SCALe]:RPOSition <RefPosition>[,
<TraceName>]
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.
Suffix:
<Wnd>
.
Number of an existing diagram area (defined by means of
DISPlay[:WINDow<Wnd>][:STATe] ON). This suffix is
ignored if the optional <TraceName> parameter is used.
<WndTr> Existing trace number, assigned by means of DISPlay[:
WINDow<Wnd>]:TRACe<WndTr>:FEED. This suffix is ignored if
the optional <TraceName> parameter is used.
Parameters:
<RefPosition> Value of the reference position in percent. The top of the y-axis
is defined to have a reference position of 100%, while the bot-
tom of the y-axis is defined to have a reference position of 0%.
Range: 0% to 100%
*RST: 80%
Default unit: %
