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.
Target Format
"Lin Mag"
"dB Mag"
"Phase"
"Phase unwrap"
"Real"
"Imag"
"SWR"
"Default"
Remote command:
CALCulate<Chn>:MARKer<Mk>:SEARch:FORMat
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:

If the search is successful, the active marker is moved to the next smaller/larger stimu-
lus value with this target value. Use "Search Left"/"Search Right" repeatedly to locate
the other ones.

Description
Magnitude of z, unconverted.
Magnitude of z [dB]
Phase of z [°]
Unwrapped phase of z comprising
the complete number of 360°
phase rotations [°]
Real part of z
Imaginary part of z
(Voltage) Standing Wave Ratio
Identical to trace format.
Note: the Smith and Polar traces
use "Lin Mag" as the default for-
mat for target value.
Target Value to the left/right of the active marker's stimulus value within

Target Value.
Formula
|z| = sqrt (x
Mag(z) = 20 log|z| dB
φ (z) = arctan (y/x)
Ф(z) = φ (z) + 2k·360°
Re(z) = x
Im(z) = y
SWR = (1 + |z|) / (1 – |z|)
