1. Introduce the negative offset CW out-of-band interferer.
The negative offset CW out-of-band interferer is made available at the RF output of the
external signal source. The amplitude of this interferer is
−
15.00 dBm.
On the external signal source:
a. Set the waveform type to CW.
b. Set the RF output frequency to a value between 1 MHz and 1900 MHz.
c. Set the RF output amplitude to
−
15 dBm.
d. Activate the RF output.
2. Measure the BER of the BS in the presence of the negative offset CW out-of-band
interferer.
The controller or BER test platform is measuring the bit error ratio of the BS in the
presence of both the RF output waveform from ESG 1 and the negative offset CW
out-of-band interferer from the external signal source.
3. Record the BER measurement results for the negative offset CW out-of-band interferer
in the column titled, “Negative Frequency Offset Interferer BER Value” in Table 2-55.
4. Introduce the positive offset CW out-of-band interferer.
The positive offset CW out-of-band interferer is made available at the RF output of the
external signal source. The amplitude of this interferer is
−
15.00 dBm.
On the external signal source:
a. Set the waveform type to CW.
b. Set the RF output frequency to a value between 2000 MHz and 12750 MHz.
c. Set the RF output amplitude to
−
15 dBm.
d. Activate the RF output.
5. Measure the BER of the BS in the presence of the positive offset CW out-of-band
interferer.
The controller or BER test platform is measuring the bit error ratio of the BS in the
presence of both the RF output waveform from ESG 1 and the positive offset CW
out-of-band interferer from the external signal source.
6. Record the BER measurement results for the positive offset CW out-of-band interferer
in the column titled, “Positive Frequency Offset Interferer BER Value” in Table 2-55
.
7. Compare all of the values with the specification limitations and assign a PASS/FAIL
status to the BS.
