41. Use the following formula to calculate the Error value for the absolute power accuracy of the MS272xC
at +10 dBm:
Error = Measured Power –10
42. Record the calculated Error value into the "Error" column of
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
