Using markers in the Smith diagram
In addition to the standard marker functionality, the Smith chart also features several
marker output formats.
In its default state, the marker position is specified by the marker frequency and com-
plex resistance in Ω. The complex resistance in that case is calculated according to:
(real component) + j (imaginary component)
1. Press the "Mkr" key to open the marker menu.
2. Select the "Marker Mode" menu item.
3. Select the marker mode of your choice.
● "dB Magnitude + Phase"
Shows the magnitude (in dB) and the phase at the current marker position.
● "Lin Magn + Phase (Rho)"
Shows the converted magnitude (in %) and the phase (in rho) at the current
marker position.
● "Real + Imag (Rho)"
Shows the real and imaginary components at the current marker position.
● "R + jX"
Shows the real and imaginary components of the impedance at the marker
position. The imaginary component is converted to inductance or capacitance.
Marker frequency and sign are taken into account.
● "G + jB"
Shows the real and imaginary components of the admittance at the marker
position. The imaginary component is converted to inductance or capacitance.
Marker frequency and sign are taken into account.
● "(R + jX / Z0)"
Shows the real and imaginary components of the standardized impedance.
● "(G + jB / Y0)"
Shows the real and imaginary components of the standardized admittance.
Selecting the reference impedance for the Smith diagram
The default reference impedance (the matching point in the center of the Smith chart)
is 50 Ω. It is, however, also possible to measure the reflection on networks with
another impedance.
1. Press the "Mkr" key to open the marker menu.
2. Select the "Marker Mode" menu item.
