Chapter 1: Introduction
Thank you for purchasing a SIR®30 GPR control unit from GSSI. The SIR 30 represents the current state
of the art in high-speed, multi-channel GPR data acquisition systems. The SIR 30 has been designed to
work with any of GSSI’s current and older line of GPR antennas. The SIR 30 also offers many integration
options, so it is easy to integrate GPR to a multi-method data collection vehicle.
Please take a moment to unpack your order and ensure that everything is present. Contact GSSI or your
local GSSI representative immediately if you notice anything missing or damaged. A GSSI representative
can be reached at (603)-893-1109, 8:30 AM – 5:00 PM US Eastern Time, Monday-Friday. You can also
email [e-mail].
GSSI recommends that the User(s) completely review this manual before using your new SIR 30.
Unpacking the Box
Your new SIR 30 comes in a Pelican Model 1650 transit case with custom-cut protective foam. The transit
case has been designed to protect your SIR 30 from the elements and from damage. GSSI recommends
keeping your SIR 30 in its protective case when not in use.
The basic SIR 30 system comes with:
•SIR 30 controller
•AC Power supply: Power adapter for powering the SIR 30 from and AC outlet.
•SIR 30 User Manual
•Documentation CD: The CD contains an electronic version of this manual as well as all of
GSSI’s other radar systems and antenna manuals.
•SIR 30 Maintenance Tool: This is a USB Key containing tools to maintain the system and install
updates to your SIR 30 controller and user interface.
•Transit Case: The Pelican 1650 case containing all of the system components.
The User may also want to consider adding some accessories to your SIR 30. These are available from
GSSI as a separate purchase. Optional accessories include:
•A Panasonic ToughBook® laptop computer configured to run the SIR 30 user interface as a client
computer.
•Rugged Ethernet cross connect cable (3 or 7 meter lengths) for connecting the SIR 30 to a laptop
computer.
•DC power cable with battery clips.
•Rugged HDMI cable (2 meters) for connecting the SIR 30 to an HDMI monitor.

Key New Features of the SIR 30
Increased Data Acquisition Speed: The SIR 30 can transmit at a maximum Pulse Repetition Frequency
(PRF) of 800 KHz. This PRF enables the SIR 30 to collect more than three-quarters of a million samples
per second. Unlike other GPR systems, the maximum PRF is not reduced when operating multiple
channels simultaneously. This unique capability allows the GPR User to collect more data faster than ever
before.
Note: Not all GSSI antennas are capable of operating at the maximum Pulse Repetition Frequency of the
SIR 30. Consult your antenna manual\documentation for the appropriate antenna PRF. Setting the SIR 30
PRF higher than the maximum antenna PRF will result in poor data quality.
Data resolution: The SIR 30 incorporates fixed 32-bit sampling. This means that the SIR 30 has superior
dynamic range than other systems using 8, 16 or 24 bit sampling. The increased dynamic range will enable
the User to recover weaker signals with SIR 30 than other GPR systems.
Data Processing: The SIR 30 system applies filters and gain during data acquisition for display purposes
only. All data is stored raw. The acquisition filters and gain are stored with the data file and will be
automatically applied in RADAN 7 if so desired.
