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 description):

MLINear

MLOGarithmic

Calculate the magnitude of z, displayed in a Cartesian diagram with a logarithmic scale

PHASe

Phase of z, displayed in a Cartesian diagram with a linear vertical axis

UPHase

Unwrapped phase of z, displayed in a Cartesian diagram with a linear vertical axis

POLar

Magnitude and phase, displayed in a polar diagram

SMITh

Magnitude and phase, displayed in a Smith chart

ISMith

Magnitude and phase, displayed in an inverted Smith chart

GDELay

Group delay, displayed in a Cartesian diagram

REAL

Real part (x), displayed in a Cartesian diagram

IMAGinary

Imaginary part (y), displayed in a Cartesian diagram

SWR

Standing Wave Ratio (SWR), displayed in a Cartesian diagram

COMPlex

x, y, displayed in a polar diagram

MAGNitude

Magnitude (sqrt(x2 + y2)), displayed in a Cartesian diagram with a logarithmic scale
