CALCulate<Chn>:MARKer<Mk>:SEARch:FORMat
<SearchFormat>
Selects the format in which the target value shall be specified (see
CALCulate<Chn>:MARKer<Mk>:TARGet
Each marker may 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
MLINear
Magnitude of z, unconverted.
|z| = sqrt ( x
2
+ y
2
)
MLOGarithmic
Magnitude of z in dB
Mag(z) = 20 log|z| dB
PHASe
Phase of z
φ (z) = arctan (y/x)
UPHase
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
IMAGinary
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.
