PROJECT DESCRIPTION

Problem Statement:
Design a system that will improve the current means of probe positioning and data acquisition. In particular the system should motorize the positioning process as well as facilitate the direct receipt of data from the probe display and placement of field strength values to an EXCEL spreadsheet. The system should be implemented in such a way so as to maintain the integrity of the tests, that is, the system components cannot introduce signal reflections (at the test frequency range of 2 MHz � 4 GHz) or interfering signals that would change the field strength mapping of the system.

Benefits:
This system will significantly reduce the time and manpower requirements for each testing evolution. It will prevent the user from having to physically position the probe for each reading with the exception of the final measurements and leveling. This system will remove the need for transcribing readings to paper by hand and then enter them onto a spreadsheet. Directly receiving the data to a spreadsheet will all but eliminate the risk of transposition and transcription errors.



Mechanical Specifications:

1. Weight: within the lifting capacity of a small forklift. (Less than 400lbs)
2. Operational Accuracy: Must repetitively move the probe to the same data position within �1 cm accuracy.

Electrical Specifications:

1. Hardware:
 - Power: 120V at a max 15A (standard UL� rated wall socket) 1.8 kW available at site.
 - System lifetime: 10 years
 - Material Properties: For testing accuracy, the system cannot create reflections or signals for frequencies of 2MHz to 4GHz.
 - Interfacing: Must be able to interface with the probe currently in use
2. Software must read values to an EXCEL spreadsheet.

Environmental Specifications:

1. Temperature: All components that are not housed in a climate controlled environment must operate reliably at a temperature range 0�F-120�F. (Outside the high and low record temperatures for the area.)
2. Weather: All exposed components must be able to withstand high winds, intense rain, and be grounded against lightning strikes.
3. The positioning system must be able to operate in dusty and sandy environment. This doesn�t mean that the sponsor will not have any maintenance requirements but the system will significantly add to the maintenance needs of the measuring system.
