CALCulate<Chn>:MARKer<Mk>:SEARch:FORMat <SearchFormat>
Selects the format in which the target value shall be specified (see
CALCulate<Chn>:MARKer<Mk>:TARGet on page 890).
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.
