ENGINEERING STATEMENT For Type Certification of SECURICOR WIRELESS Model No: 70-112B FCC ID: O6E70112B I am an Electronics Engineer, a principal in the firm of Hyak Laboratories, Inc., Springfield, Virginia. My education and experience are a matter of record with the Federal Communications Commission. Hyak Laboratories, Inc. has been authorized by Securicor Wireless to make type certification measurements on the 70-112B transceiver. These tests made by me or under my supervision in our Springfield laboratory. Test data and documentation required by the FCC for Type Certification are included in this report. The data verifies that the above mentioned transceiver meets FCC requirements and Type Certification is requested. ______________________________ Rowland S. Johnson Dated: July 24, 2000 A. INTRODUCTION The following data are submitted in connection with this request for Type Certification of the 70-112B transceiver in accordance with Part 2, Subpart J of the FCC Rules. The 70-112B is a multi-bandwidth, VHF, frequency modulated transceiver intended for hand-held, portable applications in the 148 - 174 MHz band. It operates from a 7.5 volt battery pack. Output power rating is 5 watts. Both 25 kHz and 12.5 kHz channel operation is provided. B. GENERAL INFORMATION REQUIRED FOR TYPE CERTIFICATION (Paragraph 2.983 of the Rules) 1. Name of applicant: Maxon America, Inc. 2. Identification of equipment: O6E70112B a. The equipment identification label is submitted as a separate exhibit. b. Photographs of the equipment are submitted as a separate exhibit. 3. Quantity production is planned. 4. Technical description: a. 16k0F3E; 11k0F3E emission b. Frequency range: 148-174 MHz. c. Operating power of transmitter is fixed at the factory at 5 watts. d. Maximum power permitted under Part 90 of the FCC is 350 watts, and the 70-112B fully complied with those power limitations. e. The dc voltage and dc currents at final amplifier: Collector voltage: 7.3 Vdc Collector current: 1.3 A f. Function of active semiconductor device is submitted as a separate exhibit. g. Complete circuit diagram is submitted as a separate exhibit. h. A draft instruction book is submitted as a separate exhibit. i. The transmitter tune-up procedure is submitted as a separate exhibit. j. A description of circuits for stabilizing frequency is included in Appendix 1. 2 B. GENERAL INFORMATION... (Continued) k. A description of circuits and devices employed for suppression of spurious radiation and for limiting modulation is included in Appendix 2. l. Not applicable. 5. Data for 2.985 through 2.997 follow this section. C. RF POWER OUTPUT (Paragraph 2.985(a) of the Rules) RF power output was measured with a Bird 4421 RF power meter and a Narda 765-20 attenuator as a 50 ohm dummy load. Maximum power measured was 5.5 watts. (The transmitter was tuned by the factory.) D. MODULATION CHARACTERISTICS 1. A curve showing frequency response of the transmitter is shown in Figure 1. Reference level was audio signal output from a Boonton 8220 modulation meter with one kHz deviation. Audio output was measured with a Audio Precision System One TRMS voltmeter and tracking generator. 2. Modulation limiting curves are shown in Figures 2a and 2b for wide or narrow channel operation respectively, using a Boonton 8220 modulation meter. Signal level was established with a Audio Precision System One TRMS voltmeter. The curves show compliance with paragraphs 2.987(b), and 90.211(c). 3. Figure 3 is a graph of the post-limiter low pass filter which meets the requirements of paragraph 90.211(d)(1) in providing a roll-off of 60Logf/3 dB where f is audio frequency in kHz. Measurements were made following EIA RS-152B with an Audio Precision System One selective voltmeter on the Boonton 8220 modulation meter audio output. 3 D. MODULATION CHARACTERISTICS (Continued) 4. Occupied_Bandwidth (Paragraphs 2.989(c), 90.209(b)(4) and 90.210(d) of the Rules) Figures 4a, and 4b, are plots of the sideband envelope of the transmitter for 5.5 watt output taken with a Advantest R3361A spectrum analyzer. Modulation corresponded to conditions of 2.989(c)(1) and consisted of 2500 Hz tone at an input level 16 dB greater than that necessary to produce 50% modulation at 2417 Hz, the frequency of maximum response. Measured modulation under these conditions was 4.4 kHz, or 2.2 kHz for 25 or 12.5 kHz channelization respectively. For the 12.5 kHz channelization, RBW was 100 Hz, VBW 100 Hz, max hold, multiple scan per 90.210(d)(4). All plots have unmodulated carrier as 0 dBm reference. 4 FIGURE 1 MODULATION FREQUENCY RESPONSE MODULATION FREQUENCY RESPONSE FCC ID: O6E70112B FIGURE 1 5 FIGURE 2a AUDIO LIMITER CHARACTERISTICS AUDIO LIMITER CHARACTERISTICS FCC ID: O6E70112B FIGURE 2a Wideband (5 kHz) 6 FIGURE 2b AUDIO LIMITER CHARACTERISTICS AUDIO LIMITER CHARACTERISTICS FCC ID: O6E70112B FIGURE 2b Narrow band (2.5 kHz) 7 FIGURE 3 AUDIO LOW PASS FILTER RESPONSE AUDIO LOW PASS FILTER RESPONSE FCC ID: O6E70112B FIGURE 3 8 FIGURE 4a OCCUPIED BANDWIDTH ATTENUATION IN dB BELOW MEAN OUTPUT POWER Required On any frequency more than 50% up to and including 100% of the 25 authorized bandwidth, 20 kHz (10-20 kHz) On any frequency more than 100%, up to and including 250% of the 35 authorized bandwidth (20-50 kHz) On any frequency removed from the assigned frequency by more 43+10LogP = 50 than 250% of the authorized (P = 5.5 W) bandwidth (over 50 kHz) OCCUPIED BANDWIDTH (5.5 W) FCC ID: O6E70112B FIGURE 4a (5 kHz) 9 FIGURE 4b OCCUPIED BANDWIDTH ATTENUATION IN dB BELOW MEAN OUTPUT POWER Required On any frequency from the center of the authorized bandwidth f o 0 (>5.625 kHz) to 5.625 kHz removed from f o .
