AUTOMATIC ANTENNA MEASUREMENT SYSTEM

Faculty Advisor: Jiming Song

Group member: Arnold, Eric

Ho, Mike

Kang, Seok

Clients: EE417/EE517 Students

PROBLEMÖ Current system has multiple problems. The

system:Ö Only works on an old operating systemÖ Current computer not connected to network for easy

savingÖ Current computer only has floppy drive to copy data.

SOLUTIONÖ Using Visual Studio 2008, create new software

with new features and ability to operate on Windows XP and beyond.

SYSTEM OVERVIEWÖ The Power Meter

connects to PC via USB port.

The positioner connects using a RS232 connection

The user has control of both meter and software via software

User can save data to a USB flash drive.

OPERATING ENVIRONMENT Ö The operating environment of the

software will be Windows XP and beyond

The hardware will be located in Lab 3013 Coover Hall in a restricted area.

In lab, room is air conditioned. Food and drink are not allowed.

Computer is protected by Iowa State Network.

FUNCTIONAL REQUIREMENTS

Ö System records accurate data.

It is assumed current system is in working order.

Ö Computer has:Ö Windows XPÖ Network Privileges.Ö An available RS232 serial portÖ An available USB connection

NON-FUNCTIONAL REQUIREMENTS

Ö Members utilize the functions of Microsoft Visual Studio 2008

Time required to program new software with new features.

Ö Software must be reliable.

MARKETABILITY AND SURVEY Ö This software will be used in the

Radio Frequency lab, Coover 3013.

There is not a big market for this software due to uniqueness in setup.

A survey was not completed due to EE417/EE517 students lack of interaction.

Students verbal opinions were considered.

RISKS

Staying clear of the path of the positioner. Making sure the hardware in the lab was fully

functional. This includes:

The computer must be Windows XP and network connected properly.

The positioner must be fully functional.

SYSTEM DESIGNÖ To create a more user friendly environment Ö Integrate the current hardware with new

purchased antenna device. Ö Flash drive is used with new computer to save

the information. Ö Currently, no USB connections are on the

Windows 98 machine nor is it connected to the network.

Ö With the upgrade, the user will be allowed to save data to a USB drive or the network drive. We used Microsoft Visual Studio 2008 to allow this system to be upgraded to Windows XP and beyond.

INPUT AND OUTPUT SPECIFICATIONS

Input The user runs the software and follows the given

instructions The user inputs given measurements for the

positioner.

Output Text file Printing Graphs

USER INTERFACE SPECIFICATION

TESTING

ProcedureMake proper connections to PCStart SoftwareTest every option to ensure reliability

TEST RESULTS

Found system to be reliable

Software recorded accurate data.

Functions worked properly.

LESSONS LEARNED

Ö Spend more time in understanding the current system and realize our long term goal.

Ö Utilize break to accomplish above.

CONCLUSION

The design changes have been made to allow the user to save acquired data into a .txt format that allows for easy integration with other software such a Microsoft Excel or MATLAB for easy graphical analysis.

The save function allows the user to be able to input their names, date, and time that the data had been saved.

The print function had been upgraded to allow the user to print the what they had input from the previous save function.

FUTURE WORK

Design an efficient antenna to gather information.

Fabricate new antenna.

Integrate two systems together

Add feature to current software to operate both system together.
