Conducted Spurious Emissions Engineer: Poona Saber Test Date: 10/20/2016 Test Procedure The EUT was connected directly to a spectrum analyzer to verify that the EUT met the requirements for spurious emissions. The reference level was offset for the peak power output with the resolution bandwidth set for 100 KHz. The th frequency range from 30 MHz to the 10 harmonic of the fundamental transmitter was observed. Only detectable spurious emissions were recorded and plotted. For emissions that fell within restricted bands extra measurement was taken to show compliance with 15.209 limit.

Authorized Band-Edge Measurements Engineer: Poona Saber Test Date: 10/19/2016 Test Procedure This test is performed two times. Once with the hopping function turned OFF and then repeated with the hopping function turned On to make sure that the RF power remains OFF while the device is changing frequencies and that the oscillator stabilizes at the new frequency before RF power is turned back ON and overshoot of any oscillator wouldn’t cause any transmission occur during temporary periods. Following measurement setup was used and emissions at the band edge and beyond were checked to not be less than 20 dBc. For hopping mode the trace was allowed to stabilize before any measurements were taken.

Radiated Spurious Emissions Engineer: Poona Saber Test Date: 10/19/2016 Test Procedure The EUT was tested in a semi-anechoic chamber set 3m from the receiving antenna. A spectrum analyzer was used to verify that the EUT met the requirements for Radiated Spurious Emissions that fall in restricted bands per 15.209 limits. The antenna and cable correction factors were summed with the pre-amplifier gain and entered into the spectrum th analyzer as an offset to ensure accurate readings. The spectrum for each tuned frequency was examined to the 10 harmonic. Test Setup Spectrum EUT Antenna Amplifier Analyzer No other emissions were detectable. All emissions were greater than -20 dBc. Extra plot on the emission at 3.6 GHz was taken with lower span to show meeting the number of points requirement per ANSI C63.10 which requires the number of points be higher than 2*span/RBW with average detector and further investigation has been done to meet this requirement on all the other spurious emissions. p16a0004_FCC_Part 15.247_FHSS_Rev 4.0 Page 19 of 31

Occupied Bandwidth Engineer: Poona Saber Test Date: 10/18/2016 Test Procedure The EUT was connected directly to a spectrum analyzer. The Span was set wide enough to capture the entire transmitting spectrum and the resolution bandwidth was set to at least 1% of the span. The analyzer was set to max hold and when the entire spectrum was captured, the 20dB bandwidth was measured to verify that the bandwidth met the specification.
