6.8.3. Test Data

   Mobile station coupling loss (MSCL): the minimum coupling loss (in dB) between the
   wireless device and the input (server) port of the consumer booster. MSCL must be
   calculated or measured for each band of operation and provided in compliance test reports.
   MSCL includes the path loss from the wireless device, and the booster’s server antenna gain
   and cable loss. The wireless device is assumed to be an isotropic (0 dBi) antenna reference.
   Minimum standoff distances from inside wireless devices to the booster’s server antenna
   must be reasonable and specified by the manufacturer in customer provided installation
   manuals.

                                  c) Decrease the variable attenuator until the spectrum analyzer
                                     displays a signal within the band under test. Using a marker,
                                     identify the approximate center frequency of this signal on the
                                     max-hold display, increase the attenuation by 10 dB, then reset
                                     the EUT (e.g., cycle ac/dc power).
                                  d) Repeat 7.11.2c) twice to ensure that the center of the signal

                                                                                         Page 56 of 70

                                   created by the booster remains within 250 kHz of the spectrum
                                   analyzer display center frequency. If the frequency of the signal
                                   is unstable, confirm that the spectrum analyzer display is
                                   centered between the frequency extremes observed. If the signal
                                   is wider than 1 MHz, ensure that the spectrum analyzer display is
                                   centered on the signal by increasing the RBW. Reset the EUT
                                   (e.g., cycle ac/dc power) after each oscillation event, if
                                   necessary. Set the spectrum analyzer sweep trigger level to just
                                   below the peak amplitude of the displayed EUT oscillation signal.
                                e) Set the spectrum analyzer to zero-span, with a sweep time of 5
                                   seconds, and single-sweep with max-hold. The spectrum
                                   analyzer sweep trigger level in this and the subsequent steps
                                   shall be the level identified in 7.11.2d).
                                f) Decrease the variable attenuator until the spectrum analyzer
                                   sweep is triggered, increase the attenuation by 10 dB, then reset
                                   the EUT (e.g., cycle ac/dc power).
                                g) Reset the zero-span trigger of the spectrum analyzer, then
                                   repeat 7.11.2f) twice to ensure that the spectrum analyzer is
                                   reliably triggered, resetting the EUT (e.g., cycle ac/dc power)
                                   after each oscillation event if necessary.
                                h) Reset the zero-span sweep trigger of the spectrum analyzer, and
                                   reset the EUT (e.g., cycle ac/dc power).
                                i) Force the EUT into oscillation by reducing the attenuation.
                                j) Use the marker function of the spectrum analyzer to measure the
                                   time from the onset of oscillation until the EUT turns off, by
                                   setting Marker 1 on the leading edge of the oscillation signal and
                                   Marker 2 on the trailing edge. The spectrum analyzer sweep time
                                   may be adjusted to improve the time resolution of these cursors.
                                k) Capture the spectrum analyzer zero-span trace for inclusion in
                                   the test report. Report the power level associated with the
                                   oscillation separately if it can’t be displayed on the trace.
                                l) Repeat 7.11.2b) to 7.11.2k) for all operational uplink and
                                   downlink bands.
                                m) Set the spectrum analyzer zero-span sweep time for longer than
                                   60 seconds, then measure the restart time for each operational
                                   uplink and downlink band.
                                n) Replace the normal-operating mode EUT with the EUT that
                                   supports an anti-oscillation test mode.
                                o) Set the spectrum analyzer zero-span time for a minimum of 120
                                   seconds, and a single sweep.
                                p) Manually trigger the spectrum analyzer zero-span sweep, and
                                   manually force the booster into oscillation as described in
                                   7.11.2i).
                                q) When the sweep is complete, place cursors between the first two
                                   oscillation detections, and save the plot for inclusion in the test
                                   report. The time between restarts must match the manufacturer’s
                                   timing for the test mode, and there shall be no more than 5
                                   restarts.
                                r) Repeat 7.11.2m) to 7.11.2q) for all operational uplink and
                                   downlink bands.
                                Test procedure for measuring oscillation mitigation or
                                   shutdown
                                a) Connect the normal-operating mode EUT to the test equipment
                                   as shown in Figure 8.
                                b) Set the spectrum analyzer center frequency to the center of
                                   band under test, and use the following settings:
                                1) RBW=30 kHz, VBW ≥ 3 × RBW,
                                2) power averaging (rms) detector,
                                3) trace averages ≥ 100,
                                4) span ≥ 120% of operational band under test

                                                                                         Page 57 of 70

                                                                                 Report No.: TCT170321E007
                                5) number of sweep points ≥ 2 × Span/RBW.
                                c) Configure the signal generator for AWGN operation with a 99%
                                   OBW of 4.1 MHz, tuned to the frequency of 2.5 MHz above the
                                   lower edge or below the upper edge of the operating band under
                                   test. Adjust the RF output level of the signal generator such that
                                   the measured power level of the AWGN signal at the output port
                                   of the booster is 30 dB less than the maximum power of the
                                   booster for the band under test. Affirm that the input signal is not
                                   obstructing the measurement of the strongest oscillation peak in
                                   the band, and is not included within the span in the
                                   measurement.
                                1) Boosters with operating spectrum passbands of 10 MHz or less
                                   may use a CW signal source at the band edge rather than
                                   AWGN.
                                2) For device passbands greater than 10 MHz, standard CMRS
                                   signal sources (i.e., CDMA, W-CDMA, LTE) may be used instead
                                   of AWGN at the band edge.
                                d) Set the variable attenuator to a high attenuation setting such that
                                   the booster will operate at maximum gain when powered on.
                                   Reset the the EUT (e.g., cycle ac/dc power). Allow the EUT to
                                   complete its boot-up process, to reach full operational gain, and
                                   to stabilize its operation.
                                e) Set the variable attenuator such that the insertion loss for the
                                   center of the band under test (isolation) between the booster
                                   donor port and server port is 5 dB greater than the maximum
                                   gain, as recorded in the maximum gain test procedure (see 7.3),
                                   for the band under test.
                                f) Verify the EUT shuts down, i.e., to mitigate the oscillations. If the
                                   booster does not shut down, measure and verify the peak
                                   oscillation level as follows.
                                1) Allow the spectrum analyzer trace to stabilize.
                                2) Place the marker at the highest oscillation level occurring within
                                   the span, and record its output level and frequency.
                                3) Set the spectrum analyzer center frequency to the frequency
                                   with the highest oscillation signal level, and reduce the span such
                                   that the upper and lower adjacent oscillation peaks are within the
                                   span.
                                4) Use the Minimum Search Marker function to find the lowest
                                   output level that is within the span, and within the operational
                                   band under test, and record its output level and frequency.
                                5) Affirm that the peak oscillation level measured in 7.11.3f2), does
                                   not exceed by 12.0 dB the minimal output level measured in
                                   7.11.3f)4). Record the measurement results of 7.11.3f2) and
                                   7.11.3f4) in tabular format for inclusion in the test report.
                                6) The procedure of 7.11.3f1) to 7.11.3.f5) allows the spectrum
                                   analyzer trace to stabilize, and verification of shutdown or
                                   oscillation level measurement must occur within 300 seconds.14
                                g) Decrease the variable attenuator in 1 dB steps, and repeat step
                                   7.11.3f) for each 1 dB step. Continue testing to the level when
                                   the insertion loss for the center of band under test (isolation)
                                   between the booster donor port and server port is 5 dB lower
                                   than the maximum gain (see 7.3).
                                h) Repeat 7.11.3a) to 7.11.3g) for all operational uplink and
                                   downlink bands.

     Test setup:




                                     a) Place the EUT on an OATS or semi-anechoic
                                        chamber turntable 3 m from the receiving antenna.15
                                     b) Connect the EUT to the test equipment as shown in
                                        Figure 10 beginning with the uplink output (donor)
                                        port.
                                     c) Set the signal generator to produce a CW signal with
                                        the frequency set to the center of the operational
                                        band under test, and the power level set at PIN as
                                        determined from measurement results per 7.2.
                                     d) Measure the radiated spurious emissions from the
     Test Procedure:
                                        EUT from the lowest to the highest frequencies as
                                        specified in § 2.1057. Maximize the radiated
                                        emissions by using the procedures described in ANSI
                                        C63.4.
                                     e) Capture the peak emissions plots using a peak
                                        detector with Max-Hold for inclusion in the test report.
                                        Tabular data is acceptable in lieu of spectrum
                                        analyzer plots.
                                     f) Repeat 7.12c) through 7.12e) for all uplink and
