#### CALCulate<Chn>:FORMat...

This subsystem determines a post-processing of the measured data in order to obtain various display formats.

##### CALCulate<Chn>:FORMat
MLINear | MLOGarithmic | PHASe | UPHase | POLar | SMITh | ISMith | GDELay | REAL | IMAGinary | SWR | COMPlex | MAGNitude

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 Trace - Format
and CALCulate<Chn>:PARameter
commands. Nevertheless, it is advisable to check which display formats are generally appropriate for an analysis of a particular measured quantity; see Measured Quantities and Display Formats
.

<Chn> | Channel number used to identify the active trace. If unspecified the numeric suffix is set to 1.
Parameters | See list of parameters below.
*RST value | MLOGarithmic
SCPI, Command Types | Confirmed, command or query
Example: | CALC4:PAR:SDEF 'Ch4Tr1', 'S11' Create channel 4 and a trace named Ch4Tr1 to measure the input reflection coefficient S11. The trace becomes the active trace in channel 4. CALC4:FORM MLIN; DISP:WIND:TRAC:FEED 'CH4TR1' Calculate the magnitude of S11 and display it in a linearly scaled Cartesian diagram.

Assume that the result at a sweep point is given by the complex quantity z = x + jy. The meaning of the parameters is as follows (see also table in CALCulate<Chn>:MARKer<Mk>:FORMat
