Description The MKAR command makes marker #1 a reference marker and marker #3 an active amplitude-left marker. The MKAR command also activates
the relative-marker mode, which displays two markers and calculates the wavelength and amplitude dierence between them. When this mode is active, the MKA and MKAR commands specify the amplitude dierence between the amplitude-right and reference markers. If the vertical scale of the display is logarithmic, the dierence between the markers is in decibel units. If the vertical scale is linear, the dierence between the markers is a power ratio. In the syntax diagrams, X represents the ratio of the marker amplitudes.
