34. Set the MN63A attenuator to 0dB.
35. On the MT821xE press the Center Freq submenu key, enter 881.5, and then press the MHz submenu key.
36. Press the Measurements main menu key, then the RF Measurement submenu key, then the Channel
Spectrum submenu key.
37. On the MG3700A, turn On the RF output and use the knob to adjust power level to read the value of
PMA.10C on Sensor A.
38. Record the MG3700A power level setting (MG3700A.10) in Table A-43, “Option 44, Power Level Setting
Components Characterization Table” on page A-34.
39. On the MT821xE, press the Amplitude key and then press the Adjust Range submenu key.
40. Record the channel power reading in the Measured Power column of the +10 dBm row of Table A-44,
“Option 44, WCDMA Absolute Power Accuracy” on page A-34.
41. Use the following formula to calculate the absolute power accuracy of the MT821xE at +10 dBm:
Error = Measured Power –10
