Description and Method of Exercising the EUT
The JBL On Tour XTB is a Bluetooth Portable Loudspeaker. Its function is to provide audio amplification from
audio, USB or a Bluetooth paired device. For RF testing, special cables for connecting to both a parallel port
and a serial port were added to control the radio circuit board by using test software in a personal computer
(PC). The antenna was bypassed by a cable pigtail to provide conducted measurements. The RF circuit was
programmed for low, mid or high channel, hopping or single channel mode and disconnected from the PC to
be carried into the test set up. The batteries allowed the program to continue as the EUT was returned to be
powered by the Wall Wart. Therefore the fresh batteries did not degrade during testing. BlueTooth rf
communication is two way continuous. There was no provision made to test in receive mode. FCC section B
testing was performed for non-BlueTooth mode when the EUT was exercised with input from a CD player.
The EUT was exercised by a BlueTooth paired device transmitting a stream of MP3 file formatted audio music
for standard use mode. This produced digital emissions in hopping mode.
Prescans with the EUT powered by the Wall Wart proved worse case over the EUT powered by 4 1.5 V
batteries. Audio cable was inserted in the audio input port. The USB cable was inserted in its port. This USB’s
only function is to recharge a cell phone with no data connection.
The EUT’s performance during test was evaluated against the performance criterion specified by applicable
test standards. Performance results are detailed in the test results section of this report.
