6. MAXMIUM OUTPUT POWER

 6.1 Limit
  According to §74.861(e) (1), the power may not exceed the following values:
  (i) 54-72, 76-88, and 174-216 MHz bands: 50 mW EIRP
  (ii) 470-608 and 614-698: 250 mW conducted power
  (iii) 600 MHz duplex gap: 20 mW EIRP


 6.2 Test Procedure
  1). EUT was placed on a 1.50 meter high non-conductive stand at a 3 meter test distance from the receive
  antenna. A receiving antenna was placed on the antenna mast 3 meters from the EUT for emission
  measurements. The height of receiving antenna is 1.50m. Detected emissions were maximized at each
  frequency by rotating the EUT through 360° and adjusting the receiving antenna polarization. The radiated
  emission measurements of all transmit frequencies in three channels (High, Middle, Low) were measured with
  peak detector.
  2). A log-periodic antenna or double-ridged waveguide horn antenna shall be substituted in place of the EUT.
  The log-periodic antenna will be driven by a signal generator and the level will be adjusted till the same power
  value on the spectrum analyzer or receiver. The level of the spurious emissions can be calculated through the
  level of the signal generator, cable loss, the gain of the substitution antenna and the reading of the spectrum
  analyzer or receiver.
  3). The EUT is then put into continuously transmitting mode at its maximum power level during the test.Set
  Test Receiver or Spectrum RBW=1MHz,VBW=1MHz, And the maximum value of the receiver should be
  recorded as (Pr).
  4). The EUT shall be replaced by a substitution antenna. In the chamber, a substitution antenna for the
  frequency band of interest is placed at the reference point of the chamber. An RF Signal source for the
  frequency band of interest is connected to the substitution antenna with a cable that has been constructed to
  not interfere with the radiation pattern of the antenna. A power (PMea) is applied to the input of the substitution
  antenna, and adjusts the level of the signal generator output until the value of the receiver reach the
  previously recorded (Pr). The power of signal source (PMea) is recorded. The test should be performed by
  rotating the test item and adjusting the receiving antenna polarization.
  5). A amplifier should be connected to the Signal Source output port. And the cable should be connect
  between the Amplifier and the Substitution Antenna. The cable loss (Pcl), the Substitution Antenna Gain (Ga)
  and the Amplifier Gain (PAg) should be recorded after test.
  The measurement results are obtained as described below:
  Power (EIRP) =PMea- PAg - Pcl + Ga
  6). this value is EIRP since the measurement is calibrated using an antenna of known gain (2.15 dBi) and
  known input power.
  7). ERP can be calculated from EIRP by subtracting the gain of the dipole, ERP = EIRP-2.15dBi.

7. MODULATION CHARACTERISTICS

 7.1 Limit
  1). According to §74.861(e)(3): A maximum deviation of ±75 kHz is permitted when frequency modulation is
  employed.
  2). According to CFR 47 section 2.1047(a), Voice Modulation Communication Equipment, the frequency
  Response of the audio modulation circuit over a range of 100 to 5000Hz shall be measured.
  3). Equipment which employs modulation limiting. A curve or family of curves showing the percentage of
  modulation versus the modulation input voltage shall be supplied.


 7.2 Test Procedure

  7.2.1 Modulation Limit
  1). Configure the EUT as shown in figure 7-1, adjust the audio input for 60% of rated system deviation at
  1KHz using this level as a reference (0dB) and vary the input level from –20 to +20dB. Record the frequency
  Deviation obtained as a function of the input level.
  2). Repeat step 1 with input frequency changing to 300, 1000, 3000, and 12000 Hz in sequence.


  7.2.2 Audio Frequency Response
  1). Configure the EUT as shown in figure 7-1.
  2). Adjust the audio input for 20% of rated system deviation at 1 KHz using this level as a reference (0 dB).
  3). Vary the Audio frequency from 100 Hz to 5 KHz and record the frequency deviation.
  4). Audio Frequency Response = 20log10 (Deviation of test frequency/Deviation of 1 KHz reference).

 10.3 Test Procedure
  During the measurement the EUT works with a 2.5 kHz tone signal.


  10.3.1 Conducted Emission
  Conducted RF measurements of the Unwanted Radiation were made to confirm that the EUT antenna port
  conducted emissions meet the specified limit and to identify any spurious signals that require further
  investigation or measurements on the radiated emissions site.
  The transmitter output is connected to the spectrum analyzer. The resolution bandwidth is set to 1 kHz. The
  video bandwidth is set to 3 kHz. The span is set to 1MHz


  10.3.2 Radiated Emission
  1). EUT was placed on a 1.50 meter high non-conductive stand at a 3 meter test distance from the receive
  antenna. A receiving antenna was placed on the antenna mast 3 meters from the EUT for emission
  measurements. The height of receiving antenna is 1.50m. Detected emissions were maximized at each
  frequency by rotating the EUT through 360° and adjusting the receiving antenna polarization. The radiated
  emission measurements of all transmit frequencies in three channels (High, Middle, Low) were measured
  with peak detector.
  2). A log-periodic antenna or double-ridged waveguide horn antenna shall be substituted in place of the EUT.
  The log-periodic antenna will be driven by a signal generator and the level will be adjusted till the same power
  value on the spectrum analyzer or receiver. The level of the spurious emissions can be calculated through the
  level of the signal generator, cable loss, the gain of the substitution antenna and the reading of the spectrum
  analyzer or receiver.
  3). The EUT is then put into continuously transmitting mode at its maximum power level during the test.Set
  Test Receiver or Spectrum RBW=1MHz,VBW=1MHz, And the maximum value of the receiver should be
  recorded as (Pr).
  4). The EUT shall be replaced by a substitution antenna. In the chamber, an substitution antenna for the
  frequency band of interest is placed at the reference point of the chamber. An RF Signal source for the
  frequency band of interest is connected to the substitution antenna with a cable that has been constructed to
  not interfere with the radiation pattern of the antenna. A power (PMea) is applied to the input of the substitution
  antenna, and adjust the level of the signal generator output until the value of the receiver reach the previously
  recorded (Pr). The power of signal source (PMea) is recorded. The test should be performed by rotating the test
  item and adjusting the receiving antenna polarization.
  5). A amplifier should be connected to the Signal Source output port. And the cable should be connect
  between the Amplifier and the Substitution Antenna. The cable loss (Pcl) ,the Substitution Antenna Gain (Ga)
  and the Amplifier Gain (PAg) should be recorded after test.
  The measurement results are obtained as described below:
  Power(EIRP)=PMea- PAg - Pcl + Ga
  6). This value is EIRP since the measurement is calibrated using an antenna of known gain (2.15 dBi) and
  known input power.
  7). ERP can be calculated from EIRP by subtracting the gain of the dipole, ERP = EIRP-2.15dBi.

 11.4 Test Procedures
  1). 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.
  2). The corresponding audio output level from the demodulator shall be measured and recorded.
  3). 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.
  4). 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.
  5). It shall be checked that the audio output level has increased by ≤ 10 dB.
  6). 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 (lim).
  7). Measure the input level at the transmitter required to give +12 dB (lim).
