2. Adjust the amplitude of Î
or
to the required value.
In accordance with the 3GPP specification, adjust the amplitude of Î
or
to
−
103.7 dBm.
On ESG 1:
Press
Amplitude > −
103.7
> dBm.
3. Introduce the first spurious response (I
blocking
) stimulus.
I
blocking
is made available at the RF output of ESG 2. In accordance with the 3GPP
W-CDMA RF specification, the amplitude of I
blocking
is
−
44 dBm.
On ESG 2:
Activate the RF output on ESG 2 by pressing
RF On/Off (or executing the appropriate
SCPI command) until the RF ON annunciator is displayed on ESG 2.
4. Measure the BER of the data received by the UE on RMC 12.2 kbps (25.101 V3.3) in the
presence of the first spurious response stimulus.
The controller (or BER test platform) is measuring the bit error ratio of the UE in the
presence of both RF output waveforms, Î
or
(from ESG 1) and the spurious response
interferer I
blocking
(from ESG 2).
5. In Table 2-35, record the measured BER value in the column titled, “1st Spurious BER
Value.”
6. Introduce the next spurious response (I
blocking
) stimulus.
The next spurious response stimulus is made available at the RF output of ESG 2. In
accordance with the 3GPP W-CDMA RF specification, the amplitude of I
blocking
is
−
44 dBm.
On ESG 2:
a. Press
Frequency and enter the value of your second spurious response frequency.
b. Activate the RF output on ESG 2 by pressing
RF On/Off (or executing the appropriate
SCPI command) until the RF ON annunciator is displayed on ESG 2.
7. Measure the BER of the data received by the UE on RMC 12.2 kbps (25.101 V3.3) in the
presence of the second spurious response stimulus.
The controller (or BER test platform) is measuring the bit error ratio of the UE in the
presence of both RF output waveforms, Î
or
(from ESG 1) and the second spurious
response interferer I
blocking
(from ESG 2).
8. In Table 2-35, record the measured BER value in the column titled, “2nd Spurious BER
Value.”
9. Repeat Steps 6 and 7 for a third spurious response interferer.
10. In Table 2-35, record the measured BER value in the column titled, “3rd Spurious BER
Value.”
