Press the AMPT key.
Press the RANGE softkey.
Using the cursor keys or rotary knob, select SMITH
CHART from the menu.
Confirm your selection with the ENTER key or by
pressing the RANGE softkey again.
The R&S FSH displays the reflection of the DUT in the
Smith chart.
The markers in a Smith chart
As in scalar measurements, all marker functions (marker, delta marker, multi-markers) are available in
the Smith chart.
Press the MARKER key.
The R&S FSH activates the marker menu and a
marker.
Using the rotary knob, cursor keys or numeric entry,
move the marker on the complex impedance trace.
The numeric output of the market values is provided
along with the marker frequency and the complex
impedance ((real component) + j (imaginary
component)) in ohms.
The output values for the delta marker(s) are in relation to the value of the reference marker.
Limit lines in the Smith chart:
To allow visual monitoring of VSWR limits, the R&S FSH offers VSWR limit values in the Smith chart. In
a Smith chart, a VSWR limit value is shown by a circle whose center point is the reference resistance
