While most manufacturers provide table views, they generally are not too useful for anything
other than STATE mode signals. Most logic analyzer demos will show data changing on every
sample, making the table view look interesting in timing mode. However, in real usage, most
signals do not change at anywhere near the sample rate, causing the table to show a small
sample of stable data. You might have to scroll several screens before seeing the signal
transition. We have added several enhancements to the basic table view to make them truly
beneficial in real-world usage.
Compressed View
This mode compresses out the 'dead-time' between transitions, packing a lot more
information into a screen of table data. Each line of data in the table contains the
timestamp and the data. The time between lines varies and corresponds to the length of
time the previous sample was stable. In this mode, a 40 line table contains 40 transitions.
In linear (non-compressed) mode, it would contain 40 SAMPLES with perhaps NO
transitions. If multiple signals are added to the table, the compression algorithm takes ALL
signals in to account. A new line is shown any time ANY of the signals change state.
Nothing is lost or thrown away. We simply compress out the redundant information,
making the table hold more significant data. You can switch between compressed and
linear views with a single click at any time.
Although compressed mode is the most efficient way to display a signal in tabular form,
some people have trouble visualizing the non-linear, compressed time. You can Link a
compressed table with other non-compressed tables or with waveform displays to
correlate the data to a linear view. This allows BOTH an efficient table view and a linear
'in-context' view.
The included '8051.dat' example demonstrates this well. The OE signal in that example is
spread across about 1.4 Million samples but can be displayed in less than 20 table lines
when compression is enabled. When this table is linked to a waveform view, scrolling
through this small table quickly scrolls the waveform to each significant event in the OE
signal. This is a real-world example captured from a real embedded system.
Down Sampled View (Zoom)
Another approach to making the table view useful in normal timing modes is to use
down-sampling. This mode presents the data in a time-linear format, but down-samples
the data to reduce information. Down-sampling preserves linearity but reduces resolution.
This is similar to turning down the sample rate while capturing data to extend capture
times at the expense of resolution. Of course the key difference is we are post processing
the data for the table view; not ignoring data during capture. In this mode, we are simply
displaying the data with less resolution to allow the user to see more transitions while
maintaining a linear time view. Since we have not changed the underlying data itself, you
can 'zoom in' (reduce down-sampling) at any time to see more detail and actual timing.
You can also link to other full-resolution tables or waveforms to get a simultaneous view of
