Sequence Analyzer Introduction
What is the Sequence Analyzer?
User-defined parameters for the sequence determine various important characteristics of the acquisitions
(for example, the frequency of the acquired signal) and of the analysis intervals (for example, the type
and timing of measurements).
A sequence is saved as a file of tab-separated values representing sequence parameters. The parameters
that are used by the analyzer list sequencer (rather than the source list sequencer) are placed in the file
under the heading: ### Analyzer ###.
The parameters which define an acquisition are placed on one line, followed by one or more lines of
parameters for the analysis intervals within that acquisition. When a sequence is created in a spreadsheet,
the analysis-interval parameters are placed in columns to the right of the acquisition parameters, as
illustrated in Figure 1-3. (When a sequence is saved, leading tabs are inserted into the lines of
analysis-interval parameters, to preserve this spreadsheet format.) In the illustration, there are two
acquisitions (shown in red), of which the first has two analysis intervals (shown in blue) and the second
has four analysis intervals.
Figure 1-3. Basic Elements of an Analyzer Sequence
In a saved sequence, an acquisition with two analysis intervals would be represented by three lines of
parameters in the file (tabs are represented here by “>”):
### Analyzer ###

The parameters are described in detail in Chapter 2 .
