2. Signal generator setup:
3. Spectrum analyzer setup:
RBW
→
30KHz, VBW
→
300KHz, Center frequency is 1960MHz, SPAN
→
40MHz, and
Spectrum Analyzer’s offset value according the attenuation from PA output to input port of
spectrum analyzer.
4. Power meter must to be calibration and set the offset value according to attenuation
from PA output to power sensor.
5. Input PA voltage setup +30V.
6. Turn on the signal generator; adjust the output power from -6.2dBm to -23dBm with
-1dB step.
7. Read out the output power from the power meter and do subtractions of each gain
and get the gain Variation.
9. Compare the value on the power meter with the value shown on GUI, and then get
the accuracy for different frequency range and different carriers.
