To Use Polar Format Markers

The analyzer can display the marker value as magnitude and phase, or as a real/imaginary
pair: gives linear magnitude and phase,
LIN MKR
phase, gives the real value first, then the imaginary value.

You can use these markers only when you are viewing a polar display format. (The format
is available from the
NOTE For greater accuracy when using markers in the polar format, it is
recommended to activate the discrete marker mode. Press

1. To access the polar markers, press:
Format POLAR
2. Select the type of polar marker you want from the following choices:
• Choose
LIN MKR
marker. The magnitude values appear in units and the phase values appear in
degrees.
• Choose
LOG MKR
the active marker. The magnitude values appear in dB and the phase values appear
in degrees.
• Choose
Re/Im MKR
complex data is separated into its real part and imaginary part. The analyzer shows
the real part as the first marker value (M cos Θ), and the second value is the
imaginary part (M sin Θ, where M = magnitude).
