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 288 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 113.
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 289
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).
The meaning of the parameters is as follows (see also table in CALCulate<Chn>:
