The shielded enclosure prevents emissions from other sources, such as radio and TV stations from interfering with the measurements. All powerlines and signal lines entering the enclosure pass through filters on the enclosure wall. The powerline filters prevent extraneous signals from entering the enclosure on these leads. Preliminary radiated emissions tests were performed to determine the emission characteristics of the EUT. For the preliminary test, a broadband measuring antenna was positioned at a 3-meter distance from the EUT. The entire frequency range from 30MHz to 10.0GHz was investigated using a peak detector function. The final open field emission tests were then manually performed over the frequency range of 30MHz to 10.0GHz. 1) For all harmonics not in the restricted bands, the following procedure was used: a) The field strength of the fundamental was measured using a bilog antenna. The bilog antenna was positioned at a 3-meter distance from the EUT. The EUT was placed on a 80 cm high nonconductive stand. A peak detector with a resolution bandwidth of 100 kHz was used on the spectrum analyzer. b) The field strengths of all of the harmonics not in the restricted band were then measured using a double-ridged waveguide antenna. The waveguide antenna was positioned at a 3-meter distance from the EUT. The EUT was placed on a 1.5-meter-high non-conductive stand. A peak detector with a resolution bandwidth of 100kHz was used on the spectrum analyzer. c) To ensure that maximum or worst-case emission levels at the fundamental and harmonics were measured, the following steps were taken when measuring the fundamental emissions and the spurious emissions: i) The EUT was rotated so that all of its sides were exposed to the receiving antenna. ii) Since the measuring antenna is linearly polarized, both horizontal and vertical field components were measured. iii) The measuring antenna was raised and lowered for each antenna polarization to maximize the readings. iv) In instances where it was necessary to use a shortened cable between the measuring antenna and the spectrum analyzer, the measuring antenna was not raised or lowered to ensure maximized readings. Instead, the EUT was rotated through all axis to ensure the maximum readings were recorded for the EUT. d) All harmonics not in the restricted bands must be at least 20dB below levels measured at the fundamental. However, attenuation below the general limits specified in §15.209(a) is not required. 2) For all emissions in the restricted bands, the following procedure was used: a) The field strengths of all emissions below 1GHz were measured using a bi-log antenna. The bi-log antenna was positioned at a 3-meter distance from the EUT. The EUT was placed on an 80cm high non-conductive stand. A peak detector with a resolution bandwidth of 100 kHz was used on the spectrum analyzer. b) The field strengths of all emissions above 1GHz were measured using a double-ridged waveguide antenna. The waveguide antenna was positioned at a 3-meter distance from the EUT. The EUT was placed on a 1.5-meter-high non-conductive stand. A peak detector with a resolution bandwidth of 1MHz was used on the spectrum analyzer. c) To ensure that maximum or worst-case emission levels were measured, the following steps were taken when taking all measurements: i) The EUT was rotated so that all of its sides were exposed to the receiving antenna. ii) Since the measuring antenna is linearly polarized, both horizontal and vertical field components Page 69 of 96 Engineering Test Report No. 2201780-03 were measured. iii) The measuring antenna was raised and lowered for each antenna polarization to maximize the readings. iv) In instances where it was necessary to use a shortened cable between the measuring antenna and the spectrum analyzer, the measuring antenna was not raised or lowered to ensure maximized readings. Instead, the EUT was rotated through all axis to ensure the maximum readings were recorded for the EUT. d) For all radiated emissions measurements below 1GHz, if the peak reading is below the limits listed in §15.209(a), no further measurements are required. If, however, the peak readings exceed the limits listed in §15.209(a), then the emissions are remeasured using a quasi-peak detector. e) For all radiated emissions measurements above 1GHz, the peak readings must comply with the §15.35(b) limits. §15.35(b) states that when average radiated emissions measurements are specified, there also is a limit on the peak level of the radiated emissions. The limit on the peak radio frequency emissions is 20dB above the maximum permitted average emission limit applicable to the equipment under test. Therefore, all peak readings above 1GHz must be no greater than 20dB above the limits specified in §15.209(a). f) Next, for all radiated emissions measurements above 1GHz, the resolution bandwidth was set to 1MHz. The analyzer was set to linear mode with a 10Hz video bandwidth in order to simulate an average detector. An average reading was taken. If the dwell time per channel of the hopping signal is less than 100msec, then the reading obtained with the 10Hz video bandwidth may be further adjusted by a duty cycle correction factor derived from 20*log(dwell time/100msec). These readings must be no greater than the limits specified in §15.209(a).

Band Edge Compliance Manufacturer Product Model No. Serial No. Mode EUT Information Chamberlain Phoenix AC GDO Logic Board 003-0458-5 151220510865 Tx Low @ 902.25MHz Tx High @ 926.75MHz Tx Hopping Setup Format Height of Support Measurement Method Type of Test Site Type of Antennas Used Notes Test Setup Details Tabletop N/a Antenna Conducted Tabletop N/a Bench Measurement Uncertainty Measurement Type Radiated disturbance (electric field strength on an open area test site or alternative test site) (30 MHz 1000 MHz) Radiated disturbance (electric field strength on an open area test site or alternative test site) (1 GHz 6 GHz) Expanded Measurement Uncertainty 4.3 3.1 Procedure 1) Low Band Edge: a) The antenna port of the EUT was connected to the spectrum analyzer through 30dB of attenuation. b) The EUT was set to transmit continuously at the channel closest to the low band-edge hopping function disabled. c) To determine the band edge compliance, the following spectrum analyzer settings were used: o Center Frequency = 902MHz (low band-edge frequency). o Span = Wide enough to capture the peak level of the emission operating on the channel closest to the band-edge, as well as any modulation products which fall outside of the authorized band of operation. o Resolution Bandwidth (RBW) = 1% of the span. o `Max-Hold' function was engaged. d) The analyzer was allowed to scan until the envelope of the transmitter bandwidth was defined. e) The marker was set on the peak of the in-band emissions. A display line was placed 20dB down from the peak of the in-band emissions. All emissions which fall outside of the authorized band of operation must be below the 20dB down display line. (All emissions to the left of the center frequency (band-edge) must be below the display line.) f) The analyzer's display was then screenshot and saved. g) Steps (d) through (f) were repeated with the frequency hopping function enabled. 2) High Band Edge: Page 82 of 96 Engineering Test Report No. 2201780-03 a) The antenna port of the EUT was connected to the spectrum analyzer through 30dB of attenuation. b) The EUT was set to transmit continuously at the channel closest to the high band-edge hopping function disabled. c) To determine the band edge compliance, the following spectrum analyzer settings were used: o Center Frequency = 928MHz (high band-edge frequency). o Span = Wide enough to capture the peak level of the emission operating on the channel closest to the band-edge, as well as any modulation products which fall outside of the authorized band of operation. o Resolution Bandwidth (RBW) = 1% of the span. o `Max-Hold' function was engaged. d) The analyzer was allowed to scan until the envelope of the transmitter bandwidth was defined. e) The marker was set on the peak of the in-band emissions. A display line was placed 20dB (30dB for DTS systems where average power was used) down from the peak of the in-band emissions. All emissions which fall outside of the authorized band of operation must be below the 20dB (30dB for DTS systems where average power was used) down display line. (All emissions to the left of the center frequency (band-edge) must be below the display line.) f) The analyzer's display was then screenshot and saved. g) Steps (d) through (f) were repeated with the frequency hopping function enabled.
