Vectored Traces - Tektronix 11801C User Manual

Vectored Traces

Vectored traces is a display mode that enhances the appearance of dis
played traces by eliminating any gaps or discontinuities. See Figure 3 109.
The trace display area is 512 pixels (dots) wide. When a trace with a record
length of 512 samples is displayed, each sample has its own unique hori
zontal position on the display. When traces with record lengths longer than
512 samples are displayed, two or more samples must share the same
horizontal location. For a trace of 5120 samples, each horizontal place
shows the results of ten samples.
When more than one sample shares the same horizontal location, the result
ing display is always a series of vertical lines, called columns, that extend
from the top sample to the bottom sample.
The 11801C normally extends the columns to touch" adjacent columns, so
that no gaps are shown in the trace. You can turn off this trace vectoring so
that no intermediate data is assumed for display purposes.
