The automatic positioning of markers is activated in the
«Tracking»
sub-option. Select the tracking
mode from any of the modes above and then the applicable parameter to track. In addition, a
detection value must be specified for the Cross detection modes.
For example, you could set Marker 1 to track automatically the minimum VSWR values in the trace:
«Marker1»
«Tracking»
«Peak Min» «VSWR»; and Marker 2 to track the crossovers on the 50-ohm
impedance value:
«Marker2»
«Tracking»
«Cross Any
»
«Z» «50.0».
You could also program the unit to detect the bandwidth by setting
«Marker1»
«Tracking»
«Cross
Down» «VSWR» «2.0»; and
«Marker2»
«Tracking»
«Cross Up
»
«VSWR» «2.0».
Navigator B will be used to move to the different detection points, except for the Max and Min
tracking modes where logically there is only a single detection point.
The tracking mode for each marker is shown in the markers information window. This information is
displayed in red if either the data is not available or if the tracking condition cannot be resolved;
otherwise it is displayed in green.
The screenshot below shows Marker1 tracking the minimum value of VSWR and Marker 2, tracking
all |Z| crossing at 50-ohms:
