9. In Table 2-27, compare both the BER values recorded in columns “10 MHz Offset
Interferer BER Value” and “15 MHz Offset Interferer BER Value” to the allowable
values in the column titled, “Specification Limitations” (both values must be within the
allowable specification for a PASS status). Record the status of the UE as PASS or FAIL
in the column titled, “PASS/FAIL Status.”
Subsection 3. Out-of-Band Blocking Characteristics Measurements
Complete the following subsections to measure out-of-band blocking characteristics on
your UE.
Part A. Band 1 Out-of-Band Blocking Characteristics Measurements
1. Introduce the negative frequency offset CW interferer for band 1.
The band 1 negative frequency offset interferer is made available at the RF output of
ESG 2. In accordance with the 3GPP W-CDMA RF specification, the center frequency of
this band 1 interferer (I
blocking
) must be between 2050 MHz and 2095 MHz. The
amplitude of I
blocking
is
−
44 dBm.
On ESG 2:
a. Press
Mod On/Off until the MOD OFF annunciator is displayed on ESG 2 to create an
unmodulated CW signal.
b. Press
Frequency and enter a value between 2050 MHz and 2095 MHz to set the
carrier frequency of the band 1 negative frequency offset CW interferer (I
blocking
).
c. Press
Amplitude >
−
44 > dBm to set the amplitude of the band 1 negative frequency
offset CW interferer.
d. Press
RF On/Off until the RF ON annunciator is displayed on ESG 2 to activate the RF
output.
2. Measure the BER of the data received by the UE on RMC 12.2 kbps (25.101 V3.3) in the
presence of the negative frequency offset interferer for band 1.
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 band 1 negative
frequency offset interferer I
blocking
(from ESG 2).
3. In Table 2-28, record the measured BER value in the column titled, “Negative
Frequency Offset Interferer BER Value.”
4. Introduce the positive frequency offset CW interferer for band 1.
The band 1 positive frequency offset interfering stimulus is made available at the RF
output of ESG 2. In accordance with the 3GPP W-CDMA RF specification, the center
frequency of this band 1 interferer (I
blocking
) must be between 2185 MHz and
2230 MHz. The amplitude of I
blocking
is −44 dBm.
