6.7.5 Target Search Tab
The "Target Search" functions use markers to locate trace points with a specific
response value ("Target Value"). The functions are unavailable if the active trace con-
tains no markers (e.g. after "All Markers Off").
Some of the "Target Search" functions are equal to other marker search functions.
Refer to the following sections:
●
Chapter 6.7.3.2, "Search Range Dialog" , on page 370
●
"Tracking" on page 369
Target Value
Specifies the target value for the search.
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
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°
