Note: 1. RF Field Strength (dBuV) = 20 log RF Voltage (uV)
2.Distance refers to the distance in meters between the measuring instrument antenna and the closed
point of any part of the device or system.
3. The emission limit in this paragraph is based on measurement instrumentation employing an
average detector.
4.Linear interpolations for frequency ranges 130-174MHz and 260-470MHz
5.the above field strength limits are specified at a distance of 3-meters and the tighter limits apply at
the band edges
(a) On any frequency or frequencies below or equal to 1000 MHz, the limits shown are based on
measuring equipment employing a CISPR quasi-peak detector function and related measurement
bandwidths, unless otherwise specified. The specifications for the measuring instrument using the
CISPR
quasi-peak detector can be found in Publication 16 of the International Special Committee on Radio
Interference (CISPR) of the International Electro technical Commission. As an alternative to CISPR
quasi-peak measurements, the responsible party, at its option, may demonstrate compliance with the
emission limits using measuring equipment employing a peak detector function, properly adjusted
for such factors as pulse desensitization, as long as the same bandwidths as indicated for CISPR
quasi-peak measurements are employed.
Note: For pulse modulated devices with a pulse-repetition frequency of 20 Hz or less and for which
CISPR quasi-peak measurements are specified, compliance with the regulations shall be
demonstrated
using measuring equipment employing a peak detector function, properly adjusted for such factors
as pulse desensitization, using the same measurement bandwidths that are indicated for CISPR
quasi-peak measurements.
(b) Unless otherwise specified, on any frequency or frequencies above 1000 MHz, the radiated
emission limits are based on the use of measurement instrumentation employing an average detector
function . Unless otherwise specified, measurements above 1000 MHz shall be performed using a
minimum resolution bandwidth of 1 MHz. When average radiated emission measurements are

Report No.: EM201200218-1 Application No.: ZJ00016126 Page 11 of 21

specified in this part, including average emission measurements below 1000 MHz, there also is a
limit on the peak level of the radio frequency emissions. Unless otherwise specified, e.g., see §§
15.250, 15.252, 15.255, and 15.509-15.519 of this part, the limit on peak radio frequency emissions
is 20 dB above the maximum permitted average emission limit applicable to the equipment under
test. This peak limit applies to the total peak emission level radiated by the device, e.g., the total
peak power level. Note that the use of a pulse desensitization correction factor may be needed to
determine the total peak emission level. The instruction manual or application note for the
measurement instrument should be consulted for determining pulse desensitization factors, as
necessary.

2).General Radiated Emission and Harmonics Radiated Emission
Test Procedure :The procedure used was ANSI Standard C63.4-2003.The receive was
scanned from 30MHz to 5000MHz/when an emission was found. the table was rotated to
produce the maximum signal strength. An initial pre-scan was performed for peak detection
mode using the receiver .The EUT was measured for both the horizontal and vertical polarities
and performed a pre-test three orthogonal planes .The worst case emissions were reported.
An initial pre-san was performed in the 3m chamber using the spectrum analyzer in peak
detection mode. Quasi-peak measurements were conducted based on the peak sweep graph.
The EUT was measure by Bilog antenna with a orthogonal polarities.
The field strength is calculated by adding the Antenna Factor, Cable Factor &
Preamplifier .The basic equation with a sample calculation is as follows:
Final Test Level=Receiver Reading+ Antenna Factor + Cable Factor – Preamplifier Factor
