1. Set the desired measurement conditions of the signal analyzer

as follows:

a. For SFDR measurement, set the center frequency to 5.8

GHz, the frequency span to 5 GHz to 6 GHz.

b. For phase noise measurement, set the center frequency to

5.8 GHz and the offset frequency range to 10 Hz to 1 GHz.

2. Set the power level of the signal generator to -30 dBm with the

center frequency set at 5.8 GHz.

3. Connect the signal generator output to the RF input of the

EVAL-CN0523-EBZ.

4. Connect the RF output of the EVAL-CN0523-EBZ to the signal

analyzer.

5. Power up the EVAL-CN0523-EBZ using the 5 V power adapter.

6. Execute a measurement run on the signal analyzer.

7. Using the signal analyzer, get the phase noise value and verify

if it is approximately -114.91 dBc/Hz at 10 kHz offset.

8. Run an SFDR test and compare the readings. The expected

value is approximately 70 dBc.

9. For POUT vs. PIN test, set the power level of the signal generator

from -10 dBm to 0 dBm. Slowly ramp up the power level, then

record the corresponding output power on the signal generator.
