Using Markers
The markers provide numerical readout of trace data. Markers have a
stimulus value (the x-axis value in a Cartesian format) and a response
value (the y-axis value in a Cartesian format). In Smith chart format,
markers have a stimulus value, a resistive value, a reactive value, and a
complex impedance value. In polar format, markers have a stimulus
value, a magnitude value, and a phase value.
When you switch on a marker, and no other function is active, the
analyzer shows the marker stimulus value in the active entry area.
You can control markers with the front panel knob, the
keys, or the front panel numeric keypad. The markers are activated by
pressing the key. See Figure 4-1.
