The analyzer plots shown in this section were all taken with a correction table loaded into the analyzer. The correction table was used to account for the losses of the cables and attenuators used as part of the system to connect the EUT to the analyzer at all frequencies of interest. 2. All modes of operation and data rates were investigated. For radiated emission test, every axis (X, Y, Z) was also verified. The test results shown in the following sections represent the worst-case emissions. 3.

Test Limit The minimum 6dB bandwidth shall be at least 500 kHz. 6.2.2. Test Procedure ANSI C63.10-2013 - Section 11.8 6.2.3. Test Setting 1. The Spectrum's automatic bandwidth measurement capability was used to perform the 6dB bandwidth measurement. The "X" dB bandwidth parameter was set to X = 6. The bandwidth measurement was not influenced by any intermediate power nulls in the fundamental emission. 2. Set RBW = 100 kHz 3. VBW 3 × RBW 4. Detector = Peak 5. Trace mode = Max hold 6.

Test Limit The maximum output power shall be less 1 Watt (30dBm). The conducted output power limit specified in paragraph FCC Part 15.247(b) of this section is based on the use of antennas with directional gains that do not exceed 6 dBi. If transmitting antennas of directional gain greater than 6 dBi are used, the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs FCC Part 15.247(b)(3) of this section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi. 6.3.2. Test Procedure ANSI C63.10-2013 - Section 11.9.1.3 ANSI C63.10-2013 - Section 11.9.2.3.2 6.3.3. Test Setting Method PKPM1 (Peak Power Measurement of Signals with DTS BW 50MHz) Peak power measurements were performed only when the EUT was transmitting at its maximum power control level using a broadband power meter with a pulse sensor. The pulse sensor employs a VBW = 50MHz so this method was only used for signals whose DTS bandwidth was less than or equal to 50MHz. Average Power Measurement Average power measurements were performed only when the EUT was transmitting at its maximum power control level using a broadband power meter with a pulse sensor. The power meter implemented triggering and gating capabilities which were set up such that power measurements were recorded only during the ON time of the transmitter. 6.3.4. Test Setup 6.3.5. Test Result Refer to Appendix A.3. 15 of 46 Report No.: 2207RSU031-U2 6.4. Power Spectral Density Measurement 6.4.1. Test Limit The maximum permissible power spectral density is 8dBm in any 3 kHz band. The same method of determining the conducted output power shall be used to determine the power spectral density. 6.4.2. Test Procedure ANSI C63.10-2013 Section 11.10.2 6.4.3. Test Setting 1.

Test Procedure ANSI C63.10-2013 Section 6.3 & 6.6 & 11.13 6.7.3. Test Setting Peak Field Strength Measurements 1. Analyzer center frequency was set to the frequency of the radiated spurious emission of interest 2. RBW = 1MHz 3. VBW = 3MHz 4. Detector = peak 5. Sweep time = auto couple 6. Trace mode = max hold 7. Trace was allowed to stabilize Average Field Strength Measurements 1. Analyzer center frequency was set to the frequency of the radiated spurious emission of interest 2. RBW = 1MHz 3. VBW 1/T 4. As an alternative, the instrument may be set to linear detector mode. Ensure that video filtering is applied in linear voltage domain (rather than in a log or dB domain). Some instruments require linear display mode in order to accomplish this. Others have a setting for Average-VBW Type, which can be set to "Voltage" regardless of the display mode 5. Detector = Peak 24 of 46 6. Sweep time = auto 7. Trace mode = max hold 8. Allow max hold to run for at least 50 times (1/duty cycle) traces 6.7.4. Test Setup Report No.: 2207RSU031-U2 6.7.5.
