The amplitude of I

blocking

−

15 dBm.

On ESG 2:

a. Press

Frequency and enter a value between 1 MHz and 2025 MHz to set the carrier

frequency of the band 3 negative frequency offset CW interferer.

b. Press

Amplitude >

−

15 > dBm to set the amplitude of the band 3 negative frequency

offset CW interferer.

c. 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 3.

The controller (or BER test platform) is measuring the bit error ratio of the UE in the

presence of both RF output waveforms, Î

(from ESG 1) and the band 3 negative

frequency offset interferer I

blocking

(from ESG 2).

3. In Table 2-30, 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 3.

The band 3 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 3 interferer (I

blocking

) must be between 2255 MHz and

12750 MHz (see note at beginning of Part C). The amplitude of I

blocking

−

15 dBm.

On ESG 2:

a. Press

Frequency and enter a value between 2255 MHz and the maximum RF output

frequency of your ESG to set the carrier frequency of the band 3 positive frequency

offset CW interferer.

b. Press

Amplitude >

−

15 > dBm to set the amplitude of the band 3 positive frequency

offset CW interferer.

c. Press

RF On/Off until the RF ON annunciator is displayed on ESG 2 to activate the RF

output.

To measure blocking characteristics at frequencies beyond the RF output limitations of

ESG 2, connect the additional equipment, as shown in Figure 2-9..

Set the external source to:

a. signal type: CW

b. amplitude: −15 dBm

c. frequency: desired frequency up to 12.75 GHz

d. RF output: on
