Target Value
Specifies the target value for the search.
The VNA software allows you to specify the target value in different formats (see
below). For example, you can search for a particular phase value in a
Smith chart.
Remote command:
CALCulate<Chn>:MARKer<Mk>:TARGet
Target Format
Selects the format that is used to specify the
.
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.

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
