39. On the MS2720T, press the Amplitude main menu key and then press the Adjust Range submenu key.
40. Record the channel power reading into the “Measured Power” column of Table A-84, “RF Measurements,
WCDMA Absolute Power Accuracy” on page A-41.
41. Use the following formula to calculate the Error value for the absolute power accuracy of the MS2720T
at +10 dBm:
Error = Measured Power –10
42. Record the calculated Error value into the “Error” column of Table A-84, and verify that it is within the
listed specification.
43. Turn Off the RF output of the MG3700A.
44. Set the MN63A attenuator to 18 dB.
45. Calculate the value of the MG3700A setting (MG3700A.28) for +28 dBm Test Level by using the following
formula:
MG3700A.28 = MG3700A.10 + ATT.18
