Test Results

Antenna Requirement
Except from §15.203 of the FCC Rules/Regulations:

An intentional radiator antenna shall be designed to ensure that no antenna other than that furnished by the responsible party can be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of the section.

• The antenna(s) of the EUT are Permanently attached.
• There are no provisions for connection to an external antenna.

Result
The EUT complies with the requirement of §15.203

Maximum Radiated Power

Regulation
§15.236(d) :

1. In the bands allocated and assigned for broadcast television and in the 600 MHz service band: 50 mW EIRP

Test Procedure
Method AVGPM-G is a measurement using a gated RF average power meter.
Alternatively, measurements may be performed using a wideband gated RF power meter provided that the gate parameters are adjusted such that the power is measured only when the EUT is transmitting at its maximum power control level. Because the measurement is made only during the ON time of the transmitter, no duty cycle correction factor is required.

Occupied Bandwidth
Regulation
§15.236(f)(2) : One or more adjacent 25 kHz segments within the assignable frequencies may be combined to form a channel whose maximum bandwidth shall not exceed 200 kHz. The operating bandwidth shall not exceed 200 kHz.

Test Procedure
The occupied bandwidth is the frequency bandwidth such that, below its lower and above its upper frequency limits, the mean powers are each equal to 0.5% of the total mean power of the given emission. The following procedure shall be used for measuring 99% power bandwidth:

• The instrument center frequency is set to the nominal EUT channel center frequency. The frequency span for the spectrum analyzer shall be between 1.5 times and 5.0 times the OBW.
•  The nominal IF filter bandwidth (3 dB RBW) shall be in the range of 1% to 5% of the OBW, and VBW shall be approximately three times the RBW, unless otherwise specified by the applicable requirement.
• Set the reference level of the instrument as required, keeping the signal from exceeding the maximum input mixer level for linear operation. In general, the peak of the spectral envelope shall be more than [10 log (OBW/RBW)] below the reference level. Specific guidance is given in 4.1.5.2.
•  Step a) through step c) might require iteration to adjust within the specified range.
• Video averaging is not permitted. Where practical, a sample detection and s26ingle sweep mode shall be used. Otherwise, peak detection and max hold mode (until the trace stabilizes) shall be used.
•  Use the 99% power bandwidth function of the instrument (if available) and report the measured bandwidth.
• If the instrument does not have a 99% power bandwidth function, then the trace data points are recovered and directly summed in linear power terms. The recovered amplitude data points, beginning at the lowest frequency, are placed in a running sum until 0.5% of the total is reached; that frequency is recorded as the lower frequency. The process is repeated until 99.5% of the total is reached; that frequency is recorded as the upper frequency. The 99% power bandwidth is the difference between these two frequencies.
• The occupied bandwidth shall be reported by providing plot(s) of the measuring instrument display; the plot axes and the scale units per division shall be clearly labeled. Tabular data may be reported in addition to the plot(s).

§15.236(g) : Emissions within the band from one megahertz below to one megahertz above the carrier frequency shall comply with the emission mask in § 8.3 of ETSI EN 300 422-1 V1.4.2 (2011-08), Electromagnetic compatibility and Radio spectrum Matters (ERM); Wireless microphones in the 25 MHz to 3 GHz frequency range; Part 1: Technical characteristics and methods of measurement. Emissions outside of this band shall comply with the limits specified in section 8.4 of ETSI EN 300 422-1 V1.4.2 (2011-08).

Test Procedure

Necessary Bandwidth (BN) for Analogue Systems

• The arrangement of test equipment as shown in figure B.1 shall be used. Note that the noise meter conforms to (quasi peak) without weighting filter (flat).
• With the Low Frequency (LF) audio signal generator set to 500 Hz, the audio input level to the EUT shall be adjusted to 8 dB below the limiting threshold (-8 dB (lim)) as declared by the manufacturer.
• The corresponding audio output level from the demodulator shall be measured and recorded.
• The input impedance of the noise meter shall be sufficiently high to avoid more than 0,1 dB change in input level when the meter is switched between input and output.
• The audio input level shall be increased by 20 dB, i.e. to +12 dB (lim), and the corresponding change in output level shall be measured.
• It shall be checked that the audio output level has increased by ≤ 10 dB.
• If this condition is not met, the initial audio input level shall be increased from -8 dB (lim) in 1 dB steps until the above condition is fulfilled, and the input level recorded in the test report. This level replaces the value derived from the  manufacturer’s declaration and is defined as -8 dB (I’m).
• Measure the input level at the transmitter required to give +12 dB (lim).
• The LF generator shall be replaced with the weighted noise source to ITU-R Recommendation BS.559-2 [1], band-limited to 15 kHz as described in IEC 60244 -13 [2], and the level shall be adjusted such that the measured input to the
• transmitter corresponds to +12 dB (lim).
• If the transmitter incorporates any ancillary coding or signalling channels (e.g. pilot-tones), these shall be enabled prior to any spectral measurements.
• If the transmitter incorporates more than one audio input, e.g. stereo systems, the second and subsequent channels shall be simultaneously driven from the same noise source, attenuated to a level of -6 dB (lim).
• The transmitter RF output spectrum shall be measured, using a spectrum analyser with the following settings:
  • centre frequency: fc: Transmitter (Tx) nominal frequency;
  • dispersion (Span): fc – 1 MHz to fc + 1 MHz;
  • Resolution BandWidth (RBW): 1 kHz;
  • Video BandWidth (VBW): 1 kHz;
  • detector: Peak hold.

Necessary Bandwidth (BN) for Digital Systems
NOTE 1: This parameter also includes the limits for spectral components within the out-of-band region. Principal

Spectrum Mask measuring method for digital transmitters:

• Spectrum mask below 1 GHz, see figure 4, for the spectrum mask above 1 GHz, see figure 5.
  The transmitter shall be modulated with the test signals defined in clause 7.1.2. In any case the mask shall not be exceeded.

1. Step 1: Measure the “Carrier Power” with the spectrum analyzer setup:

   • Center Frequency = fc
   • Span = Zero span
   • Detector = RMS
   • Trace Mode = Average
   • RBW&VBW = 5 x B
   • Sweep time ≥ 2 s

2. Step 2: Measure the “Maximum Relative Level (dBc) at Specified Carrier Offsets” with the following spectrum analyzer setup:

   • Center Frequency = fc

   • Span ≥ 5 x B
     Detector = RMS
     Trace Mode = Peak Hold

   • RBW&VBW = 1 kHz

   • Sweep time ≥ 2 s

3. Step 3: Measure the “transmitter wide band noise floor”:

   • The measurement of transmitter broad band noise floor shall be carried out according to clause 8.3.1.1.
   • Start Frequency = fc + 1,75B and fc – 1 MHz below 1 GHz, Start Frequency = fc + B and fc – 1 MHz above 1 GHz.
   • Stop Frequency = fc + 1 MHz and fc – 1,75 B below 1 GHz, Stop Frequency = fc + 1 MHz and fc -B above 1 GHz.
   • Detector = RMS
   • Trace Mode = Average
   • RBW&VBW = 1 kHz
   • Sweep time ≥ 2 s

Frequency Stability
Regulation

§15.236(f) : The frequency tolerance of the carrier signal shall be maintained within ±0.005% of the operating frequency over a temperature variation of −20 degrees to +50 degrees C at normal supply voltage, and for a variation in the primary supply voltage from 85% to 115% of the rated supply voltage at a temperature of 20 degrees C. Battery operated equipment shall be tested using a new battery.

Test Procedure
Frequency stability with respect to ambient temperature

• Supply the EUT with a nominal ac voltage or install a new or fully charged battery in the EUT. If possible, a dummy load shall be connected to the EUT because an antenna near the metallic walls of an environmental test chamber could affect the output frequency of the EUT. If the EUT is equipped with a permanently attached, adjustable-length antenna, then the EUT shall be placed in the center of the chamber with the antenna adjusted to the shortest length possible. Turn ON the EUT and tune it to one of the number of frequencies shown in 5.6.

•  Couple the unlicensed wireless device output to the measuring instrument by connecting an antenna to the measuring instrument with a suitable length of coaxial cable and placing the measuring antenna near the EUT (e.g., 15 cm away), or by connecting a dummy load to the measuring instrument, through an attenuator if necessary.
  NOTE—An instrument that has an adequate level of accuracy as specified by the procuring or regulatory agency is the recommended measuring instrument.

•  Adjust the location of the measurement antenna and the controls on the measurement instrument to obtain a suitable signal level (i.e., a level that will not overload the measurement instrument but is strong enough to allow measurement of the operating or fundamental frequency of the EUT).

• Turn the EUT OFF and place it inside the environmental temperature chamber. For devices that have oscillator heaters, energize only the heater circuit.

•  Set the temperature control on the chamber to the highest specified in the regulatory requirements for the type of device and allow the oscillator heater and the chamber temperature to stabilize.

• While maintaining a constant temperature inside the environmental chamber, turn the EUT ON and record the operating frequency at startup, and at 2 minutes, 5 minutes, and 10 minutes after the EUT is energized. Four measurements in total are made.

• Measure the frequency at each of frequencies specified in 5.6.

• Switch OFF the EUT but do not switch OFF the oscillator heater.

• Lower the chamber temperature by not more that 10 °C, and allow the temperature inside the chamber to stabilize.

• Repeat step f) through step i) down to the lowest specified temperature.

Frequency stability when varying supply voltage
Unless otherwise specified, these tests shall be made at ambient room temperature (+15 °C to +25 °C). An antenna shall be connected to the antenna output terminals of the EUT if possible. If the EUT is equipped with or uses an adjustable-length antenna, then it shall be fully extended.

•  Supply the EUT with nominal voltage or install a new or fully charged battery in the EUT. Turn ON the EUT and couple its output to a frequency counter or other frequency-measuring instrument.
  NOTE—An instrument that has an adequate level of accuracy as specified by the procuring or regulatory agency is the recommended measuring instrument.

• Tune the EUT to one of the number of frequencies required in 5.6. Adjust the location of the measurement antenna and the controls on the measurement instrument to obtain a suitable signal level (i.e., a level that will not overload the measurement instrument but is strong enough to allow measurement of the operating or fundamental frequency of the EUT).

• Measure the frequency at each of the frequencies specified in 5.6.

• Repeat the above procedure at 85% and 115% of the nominal supply voltage as described in 5.13.

Radiated Emissions

AC Conducted Emissions (150 kHz to 30 MHz)
Regulation
§15.207(a) : Except as shown in paragraphs (b) and (c) of this section, for an intentional radiator that is designed to be connected to the public utility (AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency or frequencies, within the band 150 kHz to 30 MHz, shall not exceed the limits in the following table, as measured using a 50 μH/50 ohms line impedance stabilization network (LISN). Compliance with the provisions of this paragraph shall be based on the measurement of the radio frequency voltage between each power line and ground at the power terminal. The lower limit applies at the boundary between the frequency ranges.

• Decreases with the logarithm of the frequency.

Test Procedure

•  The EUT was placed 0.4 meters from the conducting wall of the shielded room with EUT being connected to the power mains through a line impedance stabilization network (LISN). Other support units were connected to the power mains through another LISN. The two LISNs provide 50 ohm / 50 μH of coupling impedance for the measuring instrument.
