Description The MKTRACK command keeps the active marker and the point it marks at the center of the display during changes in wavelength span.
When MKTRACK ON is executed, the spectrum analyzer initiates several sweeps as it reduces the span in stages. If span is reduced signicantly when marker tracking is o, the signal is likely to be outside of the measurement range.
