Motorola, Inc. FCC ID: AZ492FT5809 TEST SET-UP PROCEDURES AND TEST EQUIPMENT USED Pursuant to 47CFR 2.947 7A RF Power Out – Pursuant to 47 CFR 2.1046(a) Method of Measurement: Per TIA/EIA-603-1 2.2.1 Before measuring the RF output power, the transmitter is adjusted in accordance with the tune-up procedure outlined in Exhibit 10 to give the value of voltage and current as specified in Exhibit 6. The transmitter antenna port is then connected through an RF attenuator of the proper power rating to an HP 8901B Modulation Analyzer using an HP 8481A Power Sensor. 7B Occupied Bandwidth – Pursuant to 47 CFR 2.1049(b) Method of Measurement: Per TIA/EIA-603-1 2.2.11, TIA-EIA-102.CAAB 3.2.5 Data on occupied bandwidth is shown in the form of a spectrum analyzer display, clearly illustrating the transmitter sidebands. For analog signals, the reference line is the peak of the unmodulated carrier, over which is superimposed the sideband display generated by modulating the carrier with a 2500 Hz tone at a level 16 dB greater than that required to produce 50 percent of rated modulation. For digital voice and data, the reference line is also that of the peak value of the unmodulated carrier, the modulation is a continuously repeating 511 bit pseudo random bit sequence based on the Standard Transmitter Test Pattern from the TIA/EIA IS-102.CAAA. If tone or digital coded squelch is indicated, both the 2500 Hz tone and the indicated squelch signal are used to modulate the transmitter. During these tests, the maximum deviation is set for ±5 kHz for 25 kHz channelization and ±2.5 kHz for 12.5 kHz channelization. The limits used for the masks are those set forth in 90.210. Mask B for all transmissions: At least 25 dB down on any frequency removed from the assigned frequency by more than 50% up to 100% of the authorized bandwidth. At least 35 dB down on any frequency removed from the assigned frequency by more than 100% but not more than 250% of the authorized bandwidth. At least 43 + log 10 (RFOP) dB for any frequency removed from the assigned frequency by more than 250% of the authorized bandwidth. 7C Radiated Spurious Emissions – Pursuant to 47 CFR 2.1053 Test Site: The site, located at Plantation, Florida, is in a region reasonably free from RF interference and has been approved by the Commission for Spurious Measurements. Method of Measurement: Per TIA/EIA-603-1 2.2.12 The equipment is adjusted to obtain peak reading of received signals wherever they occur in the spectrum by: 1. Rotating the transmitter under test 2. Adjusting the antenna height The testing procedure is repeated for both horizontal and vertical polarization of the receiving antenna. Relative strength is indicated on the spectrum analyzer connected to the receiving antenna. To obtain actual radiated signal strength for each spurious and harmonic frequency observed, a standard signal generator with calibrated output is connected to a dipole antenna adjusted to that EXHIBIT 7(1/4) Motorola, Inc. FCC ID: AZ492FT5809 particular frequency. This dipole antenna is substituted for the transmitter under test. The signal generator is adjusted in output level until a reading identical to that obtained with the actual transmitter is observed on the spectrum analyzer. Signal strength is then read directly from the generator. Actual measurements are recorded on the attached graphs. The applied limits are those from FCC 90.210, radiated spurious emissions must be 43 + 10log 10 (Power out in Watts) dB down from unmodulated carrier or equivalently less than -13 dBm (50 μW) absolute level. 7D Frequency Stability – Pursuant to 47 CFR 2.1055 Method of Measurement: Per TIA/EIA-603-1 2.2.2 Temperature (non-heated crystal oscillator): Frequency measurements are made at the extremes of the temperature range -30 to +60°C and at intervals of not more than 10°C throughout the range. Sufficient time is allowed prior to each measurement for the circuit components to stabilize. Power Supply Voltage: The primary voltage was varied from 80% to 20% of the nominal supply voltage. Voltage is measured at the input to the cable normally provided with the equipment. The limits are those from FCC 90.213, ± 1.5 PPM. The results for this equipment are: Stability vs. Temperature: ±1 PPM Stability vs. Power Supply Voltage: ±1 PPM 7E Modulation Limiting -- Pursuant to 47 CFR 2.1047 Method of Measurement: Per TIA/EIA-603-1 2.2.3 The transmitter shall be adjusted for full rated system deviation. Adjust the audio input for 60% of rated deviation at 1000 Hz. Using this level as a reference (0 dB), add 20 dB to the audio input level for modulation frequencies of 300, 1000, and 3000 Hz. The recorded system deviation obtained as a function of the input frequency is shown in Exhibit 6D. FCC 2.1047 also calls for curves showing percentage of modulation versus input audio level. The recorded system deviation obtained as a function of the input level is shown in Exhibit 6E. The transmitter modulation must not exceed rated system deviation at any audio frequency input or change in input level. 7F Audio Low Pass Filtering -- Pursuant to 47 CFR 2.1047 Method of Measurement: Per TIA/EIA-603-1 2.2.15 Using a dummy microphone to generate a 1000 Hz tone into the unit. The transmitter is connected to an HP 8901B Modulation Analyzer, which sends the demodulated audio to an HP 8532A Spectrum Analyzer. The 1000 Hz audio level is then set as the 0 dB reference and the audio input frequency is swept from 3000 Hz to 16000 Hz. At each discrete audio input frequency, the HP Spectrum Analyzer is used to read the magnitude of the filter response. The applicable limits are outlined in TIA/EIA-603-1 3.2.15. For frequencies between 3000 and 15000 Hz the attenuation must be at least 40log 10 (f/3000) dB below the 1000 Hz reference. Frequencies above 15000 Hz must be at least 28 dB below the 1000 Hz reference. EXHIBIT 7(2/4) Motorola, Inc. FCC ID: AZ492FT5809 7G Audio Frequency Response -- Pursuant to 47 CFR 2.1047 Met…
