Chapter 3: Data Collection
Data Collection Setup – Single Channel
In this section, we present a systematic description of a single channel data collection with a four (4) or
two (2) channel SIR 30 system. This setup will cover data collection in the Distance mode with a survey
wheel (DMI) and a GPS.
Figure 89: System Start screen.
After powering up your SIR 30, the system display will present the Start screen as illustrated in Figure 89
above. The User should select the system of linear units they wish to use for the survey.
Note:
The User cannot switch from one system of units to another during data collection. Once the User
has selected a system of units, they cannot be changed during the course of a survey.
Step 1: System Settings

After the User has selected the desired linear units, the SIR 30 will display the System Settings menu
shown in Figure 90 below. Here, the User may enable hardware channels and specify the antenna
type(s), as well as specify the location of the GPS antenna relative to the GPR antenna(s). In this
menu, the User will also specify parameters such as horizontal scan density (SCANS/UNIT) and Units
per Mark (UNITS/MARK) and file size.
