Conducted Emissions & Radiated Emissions Transmit Mode Tests
Step 1: Copy the Hyperterm file called “iO1500R FCC Testing.HT” to the Windows
desktop. This file must be used to open Hyperterm, as it automatically sets up several
paramters like baud rate and com port to allow Hyperterm to correctly talk to the
iO1500R. Double clicking this icon opens Hyperterm to use COM1. Also, copy all
the FCC script files into a folder on the PC.
For Radiated Transmit tests, use a 50 ohm RF dummy load.
For Conducted Transmit tests, just connect a cable to the antenna port.
Step 2: Connect the product containing the iO1500R with FCC testing code to the
COM1 port of the computer. Since the iO1500R with FCC software will
communicate with the PC using RS232, the RS232 lines on the iO1500R should be
made available to the external housing of the developer’s product by way of a
connector.
Step 3: Power up the iO1500R. The Hyperterm window should show the software
initializing on the module with a copyright statement, version information, then
should present the user with a prompt that looks like this:
BERBUG>
Step 4: The module is now ready to be placed in Transmit mode. This will be
accomplished by browsing to the folder where the FCC script files were placed,
choosing the proper script file, and sending it to the module. In Hyperterm, on the top
menu line, choose:
Transfer > Send Text File > FCC_TX_806.0625.txt
This file is used for Conducted or Radiated Transmit Testing at 806.0625 MHz.
Step 5: As the script is sent to the iO1500R, Hyperterm lists the commands sent:
BERBUG> tx freq 806.0625
BERBUG> tx pseudo
BERBUG> train 200
BERBUG> mode tx
BERBUG>
Step 6: The transmitter is now on. When testing is completed, the transmitter of the
iO1500R module should be turned off with the following command in Hyperterm:
BERBUG> mode idle
To prepare for the next data point, the iO1500R module should be reset or
power cycled to start with a clean slate. Use this command to reset the iO1500R
module:
BERBUG> reset
Step 7: Repeat Steps 4 - 6 with the other 2 files for Conducted Transmit Testing:
