ISMith
Displays z in an inverted Smith diagram
GDELay
For frequency sweeps only
Calculates the group delay at the related sweep
point and displays it in a Cartesian diagram
REAL
Calculates Re(z) = x and displays it in a Cartesian
diagram
IMAGinary
Calculates Im(z) = y and displays it in a Cartesian
diagram
SWR
Calculates the standing wave ratio (1 + |z|) / (1 - |z|)
and displays it in a Cartesian diagram
LOGarithmic
Displays z in a Cartesian diagram with logarithmic
scale
CALCulate<Chn>:FORMat:WQUType
<Unit>
Selects the physical unit of the displayed trace.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<Unit>
POWer | VOLTage
Power or voltage units
*RST:
POWer
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'b1'
Create channel 4 and a trace named
Ch4Tr1
to measure the
wave quantity b
1
. The trace becomes the active trace in channel
4.
CALC4:FORM:WQUT VOLT
Select voltage units for the created trace (identified by the suffix
4).
Manual operation:
See
CALCulate<Chn>:GDAPerture:SCOunt

quency sweep steps.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<Steps>
Number of steps
Range:
1 to 10000
