Description The MKAR command makes marker #1 a reference marker and marker #3 an active amplitude-right marker. The MKAR command also activates

the relative-marker mode, which displays two markers and calculates the wavelength and amplitude di￿erence between them. When this mode is active, the MKA and MKAR commands specify the amplitude di￿erence between the amplitude-right and reference markers. If the vertical scale of the display is logarithmic, the di￿erence between the markers is in decibel units. If the vertical scale is linear, the di￿erence between the markers is a power ratio. In the syntax diagrams, X represents the ratio of the marker amplitudes.
