Occupied Bandwidth Pursuant to 47 CFR 2.989
Occupied bandwidth must be tested at 3 different data transmit modes, measured both
at high and low power output. The transmit modes are 16QAM, 64 QAM, and QPSK,
which is also known as 4 QAM.
Steps for High Power 16 QAM Transmit mode
Step 1: Connect the product containing the iO1500R with FCC testing code to the
COM1 port of the computer.
Step 2: 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 3: The module is now ready to be placed in 16 QAM Transmit mode. This will
be accomplished by browsing to the folder where the FCC RX 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 >
Occupied_BW_16QAM_High_Power.txt
Step 4: As the script is sent to the iO1500R, Hyperterm lists the commands sent:
BERBUG>
tx freq 824.9875
BERBUG>
tx pseudo
BERBUG>
train 200
BERBUG> mode tx
BERBUG>
Step 5: The transmitter is now on in 16 QAM, with data scrolling up the screen.
When testing is completed, the transmitter of the iO1500R module should be turned
off with the following command in Hyperterm:
BERBUG>
mode idle The data is still scrolling by, but just keep typing and it will
work. The data will still scroll until the next reset command.
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 6: Repeat Steps 3 - 5 with the file for Low Power 16 QAM Occupied Bandwidth:
