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
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 key.)

NOTE For greater accuracy when using markers in the polar format, it is recommended to activate
the discrete marker mode. Press
MARKERS:DISCRETE
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
magnitude values appear in units and the phase values appear in degrees.
• Choose
LOG MKR
marker. The magnitude values appear in dB and the phase values appear in degrees.
• Choose
Re/Im MKR
separated into its real part and imaginary part. The analyzer shows the real part as the first marker
value (M cos ), and the second value is the imaginary part (M sin , where M = magnitude).
