Parameters:
<SFDPortConfig> ODD | NON
ODD: odd ports are on the left and even ports are on the right
NON: ports 1 to N are on the left and ports N+1 to 2·N are on
the right
Manual operation: See "Total Port Ordering" on page 582
8.3.1.8 CALCulate:FORMat...
The
CALCulate:FORMat...
commands determine the post-processing of the mea-
sured data in order to obtain various display formats.
CALCulate<Chn>:FORMat <Type>
Defines how the measured result at any sweep point is post-processed and presented
in the graphical display.
Note: The analyzer allows arbitrary combinations of display formats and measured
quantities; see Chapter 6.3, "Format Softtool" , on page 303 and
CALCulate<Ch>:PARameter...
commands. Nevertheless, it is advisable to check
which display formats are generally appropriate for an analysis of a particular mea-
sured quantity; see
Chapter 5.2.3.3, "Measured Quantities and Trace Formats" ,
on page 100.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
<Type> MLINear | MLOGarithmic | PHASe | UPHase | POLar | SMITh |
ISMith | GDELay | REAL | IMAGinary | SWR | COMPlex |
MAGNitude | LOGarithmic
See list of parameters below.
*RST:
MLOGarithmic
Example: CALC4:PAR:SDEF 'Ch4Tr1', 'S11'
Create channel 4 and a trace named
Ch4Tr1
to measure the
input reflection coefficient S
11
. The trace becomes the active
trace in channel 4.
CALC4:FORM MLIN; :DISP:WIND:TRAC2:FEED 'CH4TR1'
Calculate the magnitude of S
11
and display it in a linearly scaled
Cartesian diagram, assigning the trace number 2.
Manual operation: See "dB Mag " on page 303
Assume that the result at a sweep point is given by the complex quantity z = x + jy.
Then the magnitude of z is calculated as
|z| = sqrt(x
2
+ y
2
)
and in phase notation we have
z = |z| e j Phase(z) , where Phase(z) = arctan(y/x).
