Check to make sure that Scans/ft (7) is adequate for your application. The general rule is the more
scans/unit that you collect, the slower your collection speed, the larger your data file, and the more
stretched your file will appear. When you are finished, click Next >.

The next window (Figure 30) will prompt you to either create a new macro, or attach one that you
have already created. A macro is nothing more than a saved list of data collection parameters. These
parameters include: filters, time range and gain settings. These will vary from job to job, so it is
possible you will have many different macros for different survey objectives.
Figure 30: Attach a Macro or Create a New One.

There are no pre-saved macros on the system, so if you are using your SIR 20 for the first time
you will need to create one. Click the button for Create New Macro and click Finish. The antenna
will initialize, you will see a clock counting a few seconds and then the following window will
open.
