The VNA software allows you to specify the target value in different formats (see Tar-
get Format below). For example, you can search for a particular phase value in a
Smith chart.
Remote command:
CALCulate<Chn>:MARKer<Mk>:TARGet
CALCulate<Chn>:MARKer<Mk>:REFerence:TARGet
Target Format
Selects the format that is used to specify the Target Value.
The selected target format applies to the current marker only: each marker can have a
different target format. The table below gives an overview on how a complex target
value z = x + jy is converted.
Target Format Description Formula
"Lin Mag" Magnitude of z, unconverted.
|z| = sqrt (x
2
+ y
2
)
"dB Mag" Magnitude of z [dB] Mag(z) = 20 log|z| dB
"Phase" Phase of z [°] φ (z) = arctan (y/x)
"Phase unwrap" Unwrapped phase of z comprising
the complete number of 360°
phase rotations [°]
Ф(z) = φ (z) + 2k·360°
"Real" Real part of z Re(z) = x
"Imag" Imaginary part of z Im(z) = y
"SWR" (Voltage) Standing Wave Ratio SWR = (1 + |z|) / (1 – |z|)
"Default" Identical to trace format.
Note: the Smith and Polar traces
use "Lin Mag" as the default for-
mat for target value.

CALCulate<Chn>:MARKer<Mk>:REFerence:SEARch:FORMat
Target Search
Activates the search and sets the active marker to the defined target value. If the target
value occurs at several stimulus values, the marker is placed to the search result with
the smallest stimulus value. The other measurement points with the same target value
can be located using the "Search Right" function.
If the target is not found (e.g. because the active trace does not contain the target
value), then the active marker is not moved away from its original position.
Remote command:
CALCulate<Chn>:MARKer<Mk>:FUNCtion:EXECute TARGet
CALCulate<Chn>:MARKer<Mk>:REFerence:FUNCtion:EXECute TARGet
CALCulate<Chn>:MARKer<Mk>:FUNCtion:RESult?
