:CALCulate:FORMat Subsystem
Commands in this subsystem define the display format for a measurement.
Graph Type
:CALCulate<Tr>:FORMat
Description
Defines the graph type for the given trace <Tr>. <Tr> is the trace number in the range 1 to 4. If no trace number is specified, then the <Tr> parameter defaults to trace number 1. <Graph Type> is the graph type to which the specified trace is set, and it must be one of the following values: 
LMAGnitude|SWR|PHASe|REAL|IMAGinary|GDELay|SMITh|
LM/2|LINPolar|LOGPolar|RIMPedance|IIMPedance
The query version of this command returns “LMAG” if the specified trace graph type is set to Log Mag, “SWR” if set to SWR, “PHAS” if set to Phase, “REAL” if set to Real, “IMAG” if set to Imaginary, “GDEL” if set to Group Delay, and “SMIT” is set to Smith chart, and “LM/2” if set to Log Mag/2 (cable loss), “LINP” if set to Linear Polar, “LOGP” if set to Log Polar, “RIMP” if set to Real Impedance, and “IIMP” if set to Imaginary Impedance.
