Analyzing Data from the Sequencer
As mentioned earlier, Sequencer data comes out as a record of records. In
many cases, however, the
Sequencer may run through a series of tests
several times. This generates an array of records. Each record represents one
run through the
Sequencer and holds other records, representing each test
within a run. The easiest way to visualize this is to imagine a cube of data in
memory, as shown in Figure 9-14.
Figure 9-14. A Logged Array of Records of Records
The array of records is called Log, because that is the name associated with
the
Sequencer output pin. To access a particular run, use array indexing
with the bracket notation.
n
Log[0] is the first run through the Sequencer, Log[1] is the second
run, and so forth.
n The main record for each run has two fields,
Test1 and Test2.
