Description The MKTYPE query returns one of the four types of active markers:

￿Position marker (normal)

￿Delta marker

￿Amplitude-left marker

￿Amplitude-right marker

The position marker (PSN) is activated by MKN and is positioned at any point on the trace meeting the wavelength or time criteria. MKPK, MKPAUSE, MKTRACK, and MKNOISE also activate the position marker. The delta marker ( DELTA) is activated by MKD and is positioned at a point, either side of the reference marker, that meets the wavelength or time criteria. The amplitude-right marker (AMPR) is activated by MKAR and is positioned to the right of marker #1 at the ￿rst point that meets the amplitude criteria. The amplitude-left marker (AMPL) is activated by MKAL and is positioned to the left of marker #1 at the ￿rst point that meets the amplitude criteria.
