2. Adjust the amplitude of Î

to the required value.

In accordance with the 3GPP specification, adjust the amplitude of Î

−

92.7 dBm.

On ESG 1: Press

Amplitude > −

92.7

> dBm.

3. Introduce the 10 MHz offset in-band interferer (I

blocking

The first in-band 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

unwanted interferer (I

blocking

) can be

10 MHz from the center frequency of Î

. The

amplitude of I

blocking

−

52.0 dBm.

On ESG 2:

Press

RF On/Off (or execute the appropriate SCPI command) until the RF ON

annunciator is displayed.

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 10 MHz offset in-band interferer.

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 10 MHz offset in-band

interferer I

blocking

(from ESG 2).

5. In Table 2-27, record the measured BER value in the column titled, “10 MHz Offset

Interferer BER Value.”

6. Introduce the 15 MHz offset in-band interferer.

The second in-band 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

unwanted interferer (I

blocking

) can be

15 MHz from the center frequency of Î

. The

amplitude of I

blocking

−

44 dBm.

On ESG 2:

a. Press

Frequency and enter a frequency value

15 MHz from the center frequency of

to change the I

blocking

carrier frequency.

b. Press

Amplitude > −

> dBm to change the I

blocking

amplitude.

c. Press

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

RF output.

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 15 MHz offset in-band interferer.

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 15 MHz offset in-band

interferer I

blocking

(from ESG 2).

8. In Table 2-27, record the measured BER value in the column titled, “15 MHz Offset

Interferer BER Value.”
