Method AVGPSD-1 or method AVGPSD-1A (alternative) shall be applied if either of the following conditions can be satisfied: 1) The EUT transmits continuously (or with a D ≥98%). 2) Sweep triggering can be implemented in such a way that the device transmits at the maximum power control level throughout the duration of each of the instrument sweeps to be averaged. This condition can generally be achieved by triggering the instrument's sweep if the duration of the sweep is equal to or shorter than the duration I of each transmission from the EUT, and if those transmissions exhibit full power throughout these durations. b. Method AVGPSD-2 or method AVGPSD-2A (alternative) shall be applied if the conditions of the preceding item a) cannot be achieved. and the transmissions exhibit a constant duty cycle during the measurement duration. Duty cycle will be considered to be constant if variations are less than ±2%. c. Method AVGPSD-3 or method AVGPSD-3A (alternative) shall be applied if the conditions of the preceding paragraphs a) and b) cannot be achieved. Method AVGPSD-3: Method AVGPSD-3 uses mms detection across ON and OFE times of the EUT with max hold. The following procedure is applicable when the EUT cannot be configured to transmit continuously (i.e. D<98%), when sweep triggering/signal gating cannot be used to measure only when the EUT is transmitting at its maximum power control level. and when the transmission duty cycle is not constant (i.e., duty cycle variations exceed ±2%), SA Setting: a. Set the instrument span to a minimum of 1.5 times the OBW. b. Set sweep trigger to "free run." c. Set the RBW = 3 kHz, VBW =10 kHz, d. Detector = RMS (power averaging). e. Sweep time = Auto couple, f. Allow max hold to run for at least 60 s or longer as needed to allow the trace to stabilize. g. Use the peak marker function to determine the maximum PSD level ⚫ If the measured value exceeds requirement, then reduce RBW (but no less than 3 kHz) and repeat (note that this may require zooming in on the emission of interest and reducing the span to meet the minimum measurement point requirement as the RBW is reduced). 3.5.5 Deviation from Test Standard No deviation. 3.5.6 EUT Operating Condition The software provided by client to enable the EUT under transmission condition continuously at lowest, middle and highest channel frequencies individually.

If the maximum peak conducted output power procedure was used to determine compliance as described in 11.9.1, then the peak output power measured in any 100 kHz bandwidth outside of the authorized frequency band shall be attenuated by at least 20 dB relative to the maximum in-band peak PSD level in 100 kHz (i.e., 20 dBc). b. If maximum conducted (average) output power was used to determine compliance as described in 11.9.2. then the peak power in any 100 kHz bandwidth outside of the authorized frequency band shall be attenuated by at least 30 dB relative to the maximum in-band peak PSD level in 100 kHz (i.e., 30 dBc). 3.6.2 Test Setup ⚫ DTS emissions in non-restricted frequency bands Subclause 11.11 of ANSI C63.10 is applicable. ⚫ DTS emissions in restricted frequency bands Subclause 11.12 of ANSI C63.10 is applicable Spectrum analyzer test configuration 3.6.3 Test Instruments …
