MKA Marker Amplitude

MKA

Marker Amplitude

Specifies the amplitude of the active marker in the current amplitude units when marker type
is of fixed or amplitude type. When queried, MKA returns the marker amplitude independent
of marker type.

Description
The MKA command specifies
the
amplitude of the active marker in current units when the
marker is the fixed or amplitude type (see “MKTYPE”). If both the delta marker and active
marker are on the screen, “MKA?;” returns the amplitude difference between the two markers.
Specifying the marker amplitude moves the marker to the point of the trace closest to the
given marker amplitude.
If the trace data format P (TDF P), is used with MKA, the result is one real value in the current
amplitude units
(AUNITS
can be used to change the current amplitude units).
