Chapter 7 Software Tools Program
Uploading a Cable List
After custom cable list has been created in Site Master Software Tools it can upload it to the Site Master. The serial communication null modem cable must be connected from the Site Master to the PC.
In the Cable Editor, select Tools and Upload Cable List. The software will confirm the up- load with a message " Upload Complete" when the operation is finished.
Querying the Site Master Cable List
Query Cable List allows the user to check and review the contents of the custom cable list in the Site Master.
In the Cable Editor, select Tools and Query Cable List. The software will download the ca- ble list from the Site Master to the PC.
Entering Antenna Factors
The antenna factor is a parameter of an antenna that is used in the calculation of field strength during radiated emissions measurement. It relates the voltage output of the mea- surement antenna to the value of the incident field producing that voltage. The units are volts output per volt/meter incident field or reciprocal meters. Antennas used for radiated emissions testing are individually calibrated (the antenna factor is directly measured) at all appropriate distances. The calibrations produce values that are defined as the “equivalent free space antenna factor.” The calibration procedure corrects for the presence of the re- flection of the antenna in the ground plane, giving the value that would be measured if the antenna were in “free space.”
Step 1. Once the Site Master Software Tools has been opened, select Antenna Editor from the Tools menu on the tool bar. A
Step 2. Click on “Edit Antenna” to enter an antenna name, description, frequencies, and antenna factors. Enter the frequencies in ascending order, starting with lowest frequency first. A maximum of 60 antenna factors may be entered. Use the ar- row keys on the keyboard to move between entries.
NOTES: Only one input of frequency and antenna factor is allowed per row. Multiple antenna factors for a single antenna must be entered individually. For example, an antenna having an antenna factor of 5 from 2.0 to 2.25 GHz and an antenna factor of 4 from 2.25 to 2.5 GHz should be entered as follows:
Frequency (MHz) | Antenna Factor |
2000 | 5 |
|
|
2251 | 4 |
|
|
2500 | 4 |
|
|
If necessary, an antenna factor of zero (0) may be entered.
Step 3. Select Save from the File menu to save the antenna factors to the hard disk.
