Title: RF Test Report for 3G MOBILE PHONE
Main Model: AC4E
Serial Model: ANDY AC4E, AC4EW
To: FCC Part 15.247: 2013, ANSI C63.4: 2009

3.
Set VBW
≥
3 x RBW.
4.
Number of points in sweep
≥
2 x span / RBW. (This gives bin-to-bin spacing
≤
RBW/2, so that narrowband signals
are not lost between frequency bins.)
5.
Sweep time = auto.
6.
Detector = RMS (i.e., power averaging), if available. Otherwise, use sample detector mode.
7.
If transmit duty cycle < 98 %, use a sweep trigger with the level set to enable triggering only on full power pulses. The
transmitter shall operate at maximum power control level for the entire duration of every sweep. If the EUT transmits
continuously (i.e., with no off intervals) or at duty cycle
≥
98 %, and if each transmission is entirely at the maximum
power control level, then the trigger shall be set to “free run”.
8.
Trace average at least 100 traces in power averaging (i.e., RMS) mode.
9.
Compute power by integrating the spectrum across the OBW of the signal using the instrument’s band power
measurement function, with band limits set equal to the OBW band edges. If the instrument does not have a band
power function, sum the spectrum levels (in power units) at intervals equal to the RBW extending across the entire
OBW of the spectrum.
Test Result: Pass.
