Factor & Over Limit Calculation

The factor is calculated by adding LISN VDF (Voltage Division Factor) and Cable Loss. The basic equation is as follows:
Factor = LISN VDF + Cable Loss The "Over limit" column of the following data tables indicates the degree of compliance with the applicable limit. For example, an Over limit of -7 dB means the emission is 7 dB below the limit. The equation for calculation is as follows:
Over Limit = Level ­ Limit Level = Read Level + Factor Note: The term "cable loss" refers to the combination of a cable and a 10dB transient limiter (attenuator).

Test Procedure Maximizing procedure was performed on the highest emissions to ensure that the EUT complied with all installation combinations. All final data was recorded in Quasi-peak detection mode except for the frequency bands 9­90 kHz, 110­ 490 kHz and above 1000 MHz, average detection modes for frequency bands 9­90 kHz and 110­490 kHz, peak and average detection modes for frequencies above 1 GHz.

For 9 kHz-30MHz, the report shall list the six emissions with the smallest margin relative to the limit, for each of the three antenna orientations (parallel, perpendicular, and ground-parallel) unless the margin is greater than 20 dB.

If the maximized peak measured value complies with under the QP/Average limit more than 6dB, then it is unnecessary to perform an QP/Average measurement.

All emissions under the average limit and under the noise floor have not recorded in the report.

Factor & Over Limit/Margin Calculation The Factor is calculated by adding the Antenna Factor and Cable Loss, and subtracting the Amplifier Gain. The basic equation is as follows:
Factor = Antenna Factor + Cable Loss - Amplifier Gain The "Over Limit/Margin" column of the following data tables indicates the degree of compliance with the applicable limit. For example, an Over Limit/margin of -7dB means the emission is 7dB below the limit. The equation for calculation is as follows:
Over Limit/Margin = Level/Corrected Amplitude ­ Limit Level / Corrected Amplitude = Read Level + Factor

FCC §15.247(a) (1) - CHANNEL SEPARATION TEST

Applicable Standard Frequency hopping systems shall have hoping channel carrier frequencies separated by a minimum of 25 kHz or the 20 dB bandwidth of the hopping channel, whichever is greater. Alternatively, frequency hopping systems operating in the 2400-2483.5 MHz band may have hopping channel carrier frequencies that are separated by 25 kHz or two-thirds of the 20 dB bandwidth of the hopping channel, whichever is greater provided the systems operate with an output power no greater than 125 mW. The system shall hop to channel frequencies that are selected at the system hopping rate from a pseudo randomly ordered list of hopping frequencies. Each frequency must be used equally on the average by each transmitter. The system receivers shall have input bandwidths that match the hopping channel bandwidths of their corresponding transmitters and shall shift frequencies in synchronization with the transmitted signals.

Test Procedure Test Method: ANSI C63.10-2013 Clause 7.8.2 1. Set the EUT in transmitting mode, maxhold the channel. 2. Set the adjacent channel of the EUT and maxhold another trace. 3. Measure the channel separation.

FCC §15.247(a) (1) - 20 dB EMISSION BANDWIDTH

Applicable Standard Alternatively, frequency hopping systems operating in the 2400­2483.5 MHz band may have hopping channel carrier frequencies that are separated by 25 kHz or two-thirds of the 20 dB bandwidth of the hopping channel, whichever is greater, provided the systems operate with an output power no greater than 125 mW.

Test Procedure
Test Method: ANSI C63.10-2013 Clause 7.8.7 & Clause 6.9.2
The following conditions shall be observed for measuring the occupied bandwidth and 20 dB bandwidth: · The transmitter shall be operated at its maximum carrier power measured under normal test conditions.
· The span of the spectrum analyzer shall be set large enough to capture all products of the modulation process, including the emission skirts, around the carrier frequency, but small enough to avoid having other emissions (e.g. on adjacent channels) within the span.
· The detector of the spectrum analyzer shall be set to "Sample". However, a peak, or peak hold, may be used in place of the sampling detector since this usually produces a wider bandwidth than the actual bandwidth (worst-case measurement). Use of a peak hold (or "Max Hold") may be necessary to determine the occupied / 20 dB bandwidth if the device is not transmitting continuously.
· The nominal IF filter bandwidth (3 dB RBW) shall be in the range of 1% to 5% of the OBW/ 20dB bandwidth and video bandwidth (VBW) shall be approximately three times RBW, unless otherwise specified by the applicable requirement.
