3-5 Option 44, 45, and/or 65 WCDMA/HSDPA Signal Analyzer VerificationChapter 3 — Options Verification
3-16 PN: 10580-00279 Rev. E MS272xC MM
39. On the MS272xC, 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-91, “Option 44, WCDMA
Absolute Power Accuracy” on page A-42.
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 Table A-91, 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
