To Use Smith Chart Markers

For greater accuracy when using markers in the Smith chart format, activate the discrete
marker mode. Press

panel knob, or enter a value from the front panel keypad to read the resistive and
reactive components of the complex impedance at any point along the trace. This is the
default Smith chart marker.
The marker annotation tells that the complex impedance is capacitive in the bottom
half of the Smith chart display and is inductive in the top half of the display.
• Choose
LIN MKR
phase of the reflection coefficient at the marker.
• Choose
LOG MKR
the phase of the reflection coefficient at the active marker. This is useful as a fast
method of obtaining a reading of the log magnitude value without changing to log
magnitude format.
• Choose
Re/Im MKR
coefficient at the marker as a real and imaginary pair.
• Choose
R+jX MKR
(the series resistance and reactance, in ohms) at the marker. Also shown is the
equivalent series inductance or capacitance.
• Choose
G+jB MKR
rectangular form. The active marker values are displayed in terms of conductance
(in Siemens), susceptance, and equivalent parallel circuit capacitance or inductance.
Siemens are the international unit of admittance and are equivalent to mhos (the
inverse of ohms).
