Measurement Functions
Run Starts acquisition of data in specified trace mode.
Stop In single trace mode or the first run of a repetitive acquisition,
Stop halts acquisition and displays the current acquisition data. For
subsequent runs in repetitive mode, Stop halts acquisition of data and
does not change current display.
Time Interval The X and O markers measure the time interval between
events occurring on one or more waveforms or states (only available
when time tagging is on).
Delta States The X and O markers measure the number of tagged
states between any two states.
Patterns The X or O marker can be used to locate the nth occurrence
of a specified pattern before or after trigger, or after the beginning of
data. The O marker can also find the nth occurrence of a pattern before
or after the X marker.
Statistics X to O marker statistics are calculated for repetitive
acquisitions. Patterns must be specified for both markers, and statistics
are kept only when both patterns can be found in an acquisition.
Statistics are minimum X to O time, maximum X to O time, average X to
O time, and ratio of valid runs to total runs.
Compare Mode Functions Performs a post-processing bit-by-bit
comparison of the acquired state data and Compare Image data.
Compare Image Created by copying a state acquisition into the
compare image buffer. Allows editing of any bit in the Compare Image to
a 1, 0 or X.
Compare Image Boundaries Each channel (column) in the compare
image can be enabled or disabled via bit masks in the compare Image.
Upper and lower ranges of states (rows) in the compare image can be
specified. Any data bits that do not fall within the enabled channels and
the specified range are not compared.
