8.3 Corrected Amplitude & Margin Calculation

The Corrected Amplitude is calculated by adding the Antenna Factor and the Cable Factor, and subtracting the
Amplifier Gain from the Amplitude reading. The basic equation is as follows:

Corr. Ampl. = Indicated Reading + Ant. Factor + Cable Loss – Ampl. Gain

The “Margin” column of the following data tables indicates the degree of compliance with the applicable limit.
For example, a margin of -6dB  V means the emission is 6dB  V below the maximum limit. The equation for
margin calculation is as follows:

Margin = Corr. Ampl. – FCC Part 15 Limit

9. Out of Band Emissions

9.1 Standard Applicable

According to §15.247 (d) In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or
digitally modulated intentional radiator is operating, the radio frequency power that is produced by the intentional
radiator shall be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level
of the desired power, based on either an RF conducted or a radiated measurement, provided the transmitter
demonstrates compliance with the peak conducted power limits. If the transmitter complies with the conducted
power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this
section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the
general limits specified in §15.209(a) is not required. In addition, radiated emissions which fall in the restricted
bands, as defined in §15.205(a), must also comply with the radiated emission limits specified in §15.209(a).

9.2 Test Procedure

According to the KDB 558074 D01 15.247 Meas Guidance v05r02, the band-edge radiated test method as
follows:

Set span = wide enough to capture the peak level of the emission operating on the channel closest to the bandedge,
as well as any modulation products which fall outside of the authorized band of operation (2310MHz to 2420MHz
for low bandedge, 2460MHz to 2500MHz for the high bandedge)
RBW = 1MHz, VBW = 1MHz for peak value measured
RBW = 1MHz, VBW = 10Hz for average value measured
Sweep = auto; Detector function = peak/average; Trace = max hold
All the trace to stabilize, set the marker on the emission at the bandedge, or on the highest modulation product
outside of the band, if this level is greater than that at the bandedge. Enable the marker-delta function, then use the
marker-to-peak function to move the marker to the peak of the in-band emission. Those emission must comply
with the 15.209 limit for fall in the restricted bands listed in section 15.205. Note that the method of measurement
KDB publication number: 913591 may be used for the radiated bandedge measurements.

According to the KDB 558074 D01 15.247 Meas Guidance v05r02, the conducted spurious emissions test method
as follows:
1. Set start frequency to DTS channel edge frequency.
2. Set stop frequency so as to encompass the spectrum to be examined.
3. Set RBW = 100 kHz.
4. Set VBW ≥ 300 kHz.
5. Detector = peak.
6. Trace Mode = max hold.
7. Sweep = auto couple.
8. Allow the trace to stabilize (this may take some time, depending on the extent of the span).
9. Use peak marker function to determine maximum amplitude of all unwanted emissions within any 100 kHz
bandwidth.
Ensure that the amplitude of all unwanted emissions outside of the authorized frequency band (excluding
