Clause 8.2.2 Transmission duration, headset EUT 94 2/94 I. Background A. EUT description The CS70 and CS70N headsets are essentially two electrically identical headsets differing only in the kind of microphone boom assembly. There is a voice tube boom assembly with an omnidirectional microphone and a noise canceling boom assembly with a directional noise canceling microphone. This document reports compliance of the headset to the test parameters of V3.3 of (draft) C63.17-2005. B. Manufacturer’s attestations, mandatory declarations and descriptions The CS70 and CS70N headsets use digital modulation. Clause 4.11 in V3.3 of (draft) C63.17-2005 requires the following declarations to be made by the manufacturer. These declarations are used in demonstrating compliance with certain sections of 47CFR15 subpart D, and in support of test parameters within V3.3 of (draft) C63.17-2005. The channel plan. Five RF carriers are used, as follows: 1928.448 MHz. 1926.720 MHz. 1924.992 MHz. 1923.264 MHz. 1921.536 MHz. Maximum EUT antenna gain GA (dBi), and orientation and polarization for maximum gain. The maximum headset EUT antenna gain is 3dBi. The antenna is elliptically polarized with the major axis of polarization parallel to the headband portion of the headset disposed away from the user’s head, and with the minor axis of polarization on the same plane as the electrical board and perpendicular headband portion of the headset. Maximum peak power level Maximum specified peak conducted power level for the headset EUTs is +10dBm. Emission bandwidth Emission bandwidth measured according to the procedures of V3.3 (draft) C63.17-2005 clause 6.1.3 for the headset EUT is 1.49MHz. Nominal receive bandwidth Nominal receive bandwidth is +/-500kHz. Frame period and time slot plan, if TDMA techniques are used The EUT system is a TDMA system which “further divides access in time” in the context of clause 6.2.2 of V3.3 (draft) C63.17-2005. Frame period is 10mS. There are 24 timeslots per frame, with one of the first 12 timeslots used for the headset transmissions and one of the last 12 timeslots used for the base transmissions. Transmit and receive timeslots are 5mS apart in time. Transient events occur during which two non-adjacent timeslots may be in use by the base during the setup of the communications channel, or by both the base and the headset EUT as the system does a soft handoff in response to interference. Minimum and maximum burst length, if TDMA techniques are used Maximum burst length is 390uS, transmissions from the headset when a communications channel is open. 3/94 Minimum and maximum operating temperature range declared to the end-user The minimum operating temperature is +4C. The maximum operating temperature is +44C. Whether a system built with the EUT does or does not operate under the provisions of 47CFR15.323(c)(10) to test for deferral only in conjunction with a companion device The EUT system does not use the provisions of 47CFR15.323(c)(10) to enable testing for access criteria only in one element of the system. The headset EUTs implement the access criteria tests. Whether a system built with the EUT does or does not implement the provisions of 47CFR15.323(c)(5) enabling the use of the upper threshold for deferral The EUT system does implement the provisions of 47CFR15.323(c)(5), and uses the upper threshold for deferral. The nominal value of the deferral threshold The nominal value of the deferral threshold implemented in the headset EUTs is -51.5dBm. This is obtained from clause 4.3.3 of V3.3 (draft) C63.17-2005, where B = 1.49 MHz as declared for the headset, P max (from clause 4.3.1) is 20.8dBm, and P EUT is 10dBm, maximum, as declared. Whether a system built using the EUT does or does not operate under the provisions of 47CFR15.323(c)(6) incorporating provisions for waiting for a channel to go clear The EUT system does not use the provisions of 47CFR15.323(c)(6) to enable access to a particular channel when that channel goes clear. Whether a system built using the EUT does or does not operate under the provisions of 47CFR15.323(c)(11) enabling the access criteria check on the receive channel while in the presence of collocated interferers The EUT system does not use the provisions of 47CFR15.323(c)(11) to enable the monitoring of a time and spectrum window blocked by a co-located transmitter. The provisions within the EUT for self-check, by which compliance with 47CFR15.319(f) is obtained The headset EUT incorporates the following provisions by which compliance with 47CFR15.319(f) is obtained: a. On powerup the unit will perform a self-test of permanent storage memory (ROM) by means of a sum/checksum validation. b. On powerup the unit will perform a self-test of critical EEPROM settings (those which if in error could result in performance outside the UPCS specification limits) by means of a sum/checksum validation. c. On powerup the unit will perform a self-test of RAM by means of a memory field write/readback/invert/write/readba…

48/94 Fig. 29 – headset EUT out-of-band emissions in the region around the 3rd harmonic, with the headset EUT transmitting on the lowest carrier, 1921.536MHz. This measurement was made according to the requirements of the text of 6.1.6, and, with the worst-case peak at –46.86dB, shows margin to the -39.5dBm specification of 7.3dB. 49/94 Fig. 30 – headset EUT out-of-band emissions in the region around the 4th harmonic, with the headset EUT transmitting on the lowest carrier, 1921.536MHz, shows greater than 25dB of margin from the -39.5dBm specification limit. 50/94 Fig. 31 – headset EUT out-of-band emissions showing the regions from DC to 5MHz, with the transmitter using the highest carrier, 1928.448MHz. This screenshot resolves the contribution made by the spectrum analyzer’s DC response. Headset EUT margin to the -39.5dBm out-of-band emissions specification exceeds 25dB in this region 51/94 Fig. 32 – headset EUT out-of-band emissions showing the region from 5MHz to 1915MHz, with the transmitter using the highest carrier, 1928.448MHz. This screenshot shows a sweep made with resolution bandwidth increased to 100kHz to improve sweep time. Headset EUT emissions at –54.42dB have margin to the -39.5dBm out-of-band emissions specification in this spectral region of 14.92dB in this region, even measured in a 10x-wider bandwidth than that of the text of the test procedure in clause 6.1.6. 52/94 Fig. 33 – headset EUT out-of-band emissions showing the regions from bandedge to -1.25MHz, and from -1.25MHz to -2.5MHz, with the headset EUT transmitting on the highest carrier, 1928.448MHz. Margins to the specification of -9.5dBm in the region from bandedge to -1.25MHz, to the specification of -29.5dBm in the region from -1.25MHz to -2.5MHz, and to the specification of -39.5dBm in the region outside -2.5MHz from the bandedge all exceed 25dB. 53/94 Fig. 34 – headset EUT out-of-band emissions showing the regions from bandedge to +1.25MHz, and from +1.25MHz to +2.5MHz, with the headset EUT transmitting on the highest carrier, 1928.448MHz. Margin to the specification of -9.5dBm in the region from bandedge to +1.25MHz is found at marker 1, at –57.60dBm, and is 48.10dBm. Margin to the specification of -29.5dBm in the region from +1.25MHz to +2.5MHz is found at marker 2, at –65.27dBm, and is 35.77dB. Margin to the specification of -39.5dBm in the region outside +2.5MHz from the bandedge exceeds 25dB 54/94 Fig. 35 – headset EUT out-of-band emissions including the regions from 1935MHz to 19.3GHz with the headset EUT transmitting on the highest carrier, 1928.448MHz. The measurement is noise-limited. The 300kHz resolution bandwidth was used in the interests of getting a manageable sweep time, 1736.5 seconds, but the 300kHz bandwidth passes considerably more unwanted emissions than the 10kHz obtained from the text of v3.3 (draft) C63.17-2005 clause 6.1.6. The expanded resolution bandwidth measurement shows the 3 rd and 4 th harmonics as frequencies that need detailed emissions measurements recorded with the proper resolution bandwidth setting, and no other spurious frequencies are close to the emissions limit. We can then re-do the test using narrow scans according to the requirements of 6.1.6 to record the level per the v3.3 (draft) C63.17-2005 clause 6.1.6 specification. 55/94 Fig. 36 – headset EUT out-of-band emissions in the region around the 3rd harmonic, with the headset EUT transmitting on the highest carrier, 1928.448MHz. This measurement was made according to the requirements of the text of 6.1.6, and, with the worst-case peak at –48.37dB, shows margin to the -39.5dBm specification of 8.87dB. 56/94 Fig. 37 – headset EUT out-of-band emissions in the region around the 4th harmonic, with the headset EUT transmitting on the highest carrier, 1928.448MHz. This measurement was made according to the requirements of the text of 6.1.6, and, with the worst-case peak at –65.70dB, shows margin to the -39.5dBm specification of 26.2dB. 57/94 B. Clause 6.2 Tests of frequency and time stability for the headset EUT The test configuration for the tests of V3.3 (draft) C63.17-2005 clauses 6.2.1.1 through 6.2.1.3 and 6.2.1 through 6.2.3 for the headset EUT is as follows: The test platform and headset EUT are configured according to test configuration #2, Standard-specific tester, headset EUT, of section (I) of this document. The CMD60 is configured to report frequency offset with modulation removed, per the general requirements of 6.2.1. The number of transmit slots over which the measurement is made by the CMD60 is adjusted using the CONFIG MENU/TX TEST/MODULATION keystroke path. Set the number to 100 slots (bursts) to capture one second of signal, since there are 100 bursts per second, to generate one measurement of the mean value of the carrier frequency. The CMD60 measurement system calculates the mean value over each 100-slot measurement. The fixed channel used during the tests is the middle carrier, 1924.992MHz. The particularities associated with the tests for each clause are discussed in the specific test report sections, following. 58/94 Fig. 38 - Headset EUT within the temperature chamber, with RF connection to EUT and with power/control cable connection to EUT. 59/94 Fig. 39 - Detail of headset EUT as tested within the temperature chamber for the tests of clause 6.2. 60/94 Clause 6.2.1 Carrier frequency stability, headset EUT.
