The analyzer resolution and video bandwidths were set to 1MHz. The Lexmark MarkNet N8052 was set to transmit at its highest output power level and with the modulation scheme that produced the highest conducted output power level. The spectrum analyzer was scanned from 30MHz to 40GHz using the max hold function to detect any out of band spurious emissions. The resulting trace was corrected for the cable loss between the test sample and the spectrum analyzer. 8.2 Out of Band Emissions at Antenna Terminals Criteria All emissions outside of the 5.15–5.35 GHz band shall not exceed an EIRP of –27 dBm/MHz. 8.3 Test Results The Lexmark MarkNet N8052 met the out of band emission at antenna terminal requirements. The following plots illustrate show that there are no spurious emissions above the -27 dBm/MHz limit. Report Number: 3127731LEX-002 Page 21 of 33 FCC Part 15C Evaluation

It was then set to transmit at its highest output power level. When necessary, a high pass filter was inserted in line with the measurement path in order to keep the fundamental emission from overloading the preamplifier. All measurements were performed with the receiving antenna 3 meters from the EUT with the exception of the 20-40GHz range which was performed at a distance of 1m. During the tests, the antenna height and EUT azimuth were varied in order to identify the maximum level of emissions from the EUT. The frequency range investigated was 30MHz up to the tenth harmonic or 40GHz (whichever was lower) for each of three fundamental frequencies (low, middle, and high channels) in each operating band. The plots were generated with multiple scans using three types of antennas (a bilog and two horns). Each plot is comprised of 37 individual scans which are pieced together within the measurement software and plotted on one set of axis. In this way it is easy to compare the field strength of the fundamental with the field strength of any spur (rather than having to search through 37 different individual scans). For each frequency scan, the turntable was rotated and the antenna scanned from 1 – 4 meters (in vertical and horizontal polarity). Each spur which was within a restricted band and close to the 15.209 limit was optimized (over the tower and turntable) and reported in a tabular format. There were no spurs within 20dB of the fundamental 9.2 Field Strength of Spurious Radiation Criteria All emissions outside of the 5.15–5.35 GHz band shall not exceed an EIRP of –27 dBm/MHz. In addition, unwanted emissions below 1 GHz must comply with the general field strength limits set forth in §15.209. Those Limits are in the table below. Table 9-1 Radiated Emission Limit for FCC §15.209(a) Radiated Emission Limits at 3 meters Frequency Quasi-Peak limits, (MHz) dB (µV/m) 30 to 88 40.0 88 to 216 43.5 216 to 960 46.0 960 and up 54.0 9.3 Test Results The Lexmark MarkNet N8052 met the field strength of spurious radiation requirements of FCC §15.209 and §15.407(b). The following graphs in Figure 9-1 through Figure 9-7 show that all harmonics and spurious emissions below the -27dBm/MHz limit and that there are no emissions above the general limits specified in §15.209(a). In the following plots, the §15.209 limit above 1GHz is 54dBuV/m. This corresponds to 75nW or -41dBm. Since there were no spurious emissions above this limit which is much lower than the -27dBm/MHz limit, it is obvious that the Lexmark MarkNet N8052 complied with the §15.407(b) limit.

The measuring receiver meets the requirements of Section One of CISPR 16 and the measuring antenna correlates to a balanced dipole. From 30 to 1000 MHz, a quasi-peak detector was used for measurement. Above 1000 MHz, average measurements were performed. Measurements of the radiated field are made with the antenna located at a distance of 3 meters from the EUT. If the field-strength measurements at 3m cannot be made because of high ambient noise level or for other reasons, measurements may be made at a closer distance, for example 1m. An inverse proportionality factor of 20 dB per decade should be used to normalize the measured data to the specified distance for determining compliance. The antenna is adjusted between 1m and 4m in height above the ground plane for maximum meter reading at each test frequency. The antenna-to-EUT azimuth is varied during the measurement to find the maximum field-strength readings. The antenna-to-EUT polarization (horizontal and vertical) is varied during the measurements to find the maximum field-strength readings. The EUT, where intended for tabletop use, is placed on a table whose top is 0.8m above the ground plane. The table is constructed of non-conductive materials. Its dimensions are 1m by 1.5m, but may be extended for larger EUT.

An AMN is required to provide a defined impedance at high frequencies across the power feed at the point of measurement of terminal voltage and also to provide isolation of the circuit under test from the ambient noise on the power lines. An AMN as defined in CISPR 16 shall be used. The EUT is located so that the distance between the boundary of the EUT and the closest surface of the AMN is 0.8m. Where a flexible mains cord is provided by the manufacturer, this shall be 1m long or if in excess of 1m, the excess cable is folded back and forth as far as possible so as to form a bundle not exceeding 0.4m in length. The EUT is arranged and connected with cables terminated in accordance with the product specification. Conducted disturbance is measured between the phase lead and the reference ground, and between the neutral lead and the reference ground. Both measured values are reported. The EUT, where intended for tabletop use, is placed on a table whose top is 0.8m above the ground plane. A vertical, metal reference plane is placed 0.4m from the EUT. The vertical metal reference-plane is at least 2m by 2m. The EUT shall be kept at least 0.8m from any other metal surface or other ground plane not being part of the EUT. The table is constructed of non-conductive materials. Its dimensions are 1m by 1.5m, but may be extended for larger EUT. Floor standing EUTs are placed on a horizontal metal ground plane and isolated from the ground plane by 3 to 12 mm of insulating material. The metal ground plane extends at least 0.5m beyond the boundaries of the EUT and has minimum dimensions of 2m by 2m.
