         connected to a spectrum analyzer.

         Limits:
         The power of any emission outside of the authorized operating frequency ranges must be attenuated below
         the transmitting power (P) by a factor of at least 43 + 10 log(P) dB. The emission limit equal to -13 dBm.
         Test Setup:              Refer to section 4.2.1 for details.
         Test Procedures:
         1. Scan up to 10th harmonic, find the maximum radiation frequency to measure.
         2. The technique used to find the Spurious Emissions of the transmitter was the antenna substitution method.
              Substitution method was performed to determine the actual ERP/EIRP emission levels of the EUT.
         Test procedure as below:
         1) The EUT was powered ON and placed on a 0.8/1.5m high table at a 3 meter semi/fully Anechoic Chamber.
              The antenna of the transmitter was extended to its maximum length. Modulation mode and the measuring
              receiver shall be tuned to the frequency of the transmitter under test.
         2) The EUT was set 3 meters away from the interference-receiving antenna, which was mounted on the top
              of a variable-height antenna tower.
         3) The disturbance of the transmitter was maximized on the test receiver display by raising and lowering from
              1m to 4m the receive antenna and by rotating through 360°the turntable. After the fundamental emission
              was maximized, a field strength measurement was made.
         4) Steps 1) to 3) were performed with the EUT and the receive antenna in both vertical and horizontal
              polarization.
         5) The transmitter was then removed and replaced with another antenna. The center of the antenna was
              approximately at the same location as the center of the transmitter.
         6) A signal at the disturbance was fed to the substitution antenna by means of a non-radiating cable. With
              both the substitution and the receive antennas horizontally polarized, the receive antenna was raised and
              lowered to obtain a maximum reading at the test receiver. The level of the signal generator was adjusted
              until the measured field strength level in step 3) is obtained for this set of conditions.
         7) The output power into the substitution antenna was then measured.
         8) Steps 6) and 7) were repeated with both antennas polarized.
         9) Calculate power in dBm by the following formula:
                                   ERP(dBm) = Pg(dBm) – cable loss (dB) + antenna gain (dBd)
                                   EIRP(dBm) = Pg(dBm) – cable loss (dB) + antenna gain (dBi)
                                                          EIRP=ERP+2.15dB
               where:
               Pg is the generator output power into the substitution antenna.
         10) Test the EUT in the lowest channel, the middle channel the Highest channel
         11) The radiation measurements are performed in X, Y, Z axis positioning for EUT operation mode, and found
              the Y axis positioning which it is worse case.
         12) Repeat above procedures until all frequencies measured was complete.
         Equipment Used:          Refer to section 3 for details.
         Test Result:             Pass

      5.9 FREQUENCY STABILITY
         Test Requirement:            FCC 47 CFR Part 2.1055 & FCC 47 CFR Part 22.355
         Test Method:                 ANSI/TIA/EIA-603-D 2010 & KDB 971168 D01v02r02
                                      The carrier frequency shall not depart from the reference frequency in excess of ±2.5
         Limits:
                                      ppm for mobile stations.
         Test Setup:                  Refer to section 4.2.2 for details.
         Test Procedures:
         1)    Use CMW 500 or CMU 200 with Frequency Error measurement capability.
              a) Temp. = −30°to + 50°C
              b) Voltage =low voltage, 3.5 Vdc, Normal, 3.7 Vdc and High voltage, 4.25 Vdc.
         2) Frequency Stability vs Temperature:
         The EUT is place inside a temperature chamber. The temperature is set to 20ºC and allowed to stabilize.
         After sufficient soak time, the transmitting frequency error is measured. The temperature is increased by 10
         degrees, allowed to stabilize and soak, and then the measurement is repeated. This is repeated until +50ºC
         is reached.
         3) Frequency Stability vs Voltage:
         The peak frequency error is recorded (worst-case).
         Equipment Used:      Refer to section 3 for details.
         Test Result:         Pass
