:CALCulate:FORMat Subsystem
Commands in this subsystem define the display format for a measurement.
:CALCulate<Tr>:FORMat <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.
Cmd Parameter: <char> <Graph Type>
(LMAGnitude|SWR|PHASe|REAL|IMAGinary|GDELay|SMITh|LM/2|
LINPolar|LOGPolar|RIMPedance|IIMPedance)
Query Response: <char> <Graph Type>
(LMAG|SWR|PHAS|REAL|IMAG|GDEL|SMIT|LM/2|LINP|
LOGP|RIMP|IIMP)
Default Value: Trace 1: SMIT
Trace 2: LMAG
Trace 3: LMAG
Trace 4: SMIT
Example: To set Trace 2 graph type to Log Magnitude
