The EUT was tested in the following operating mode: - Continuous transmission with a modulated carrier at maximum power in all required channels selecting the supported data rates/modulations types.
During transmitter test the EUT was being controlled by the SW tool to operate in a continuous transmit mode on the test channel as required and in each of the different modulation modes.
Selected Transmission Modes for each Radio:
The following configurations were selected based on preliminary testing that identified those corresponding to the worst-cases:
* Bluetooth Low Energy 5.0: Transmitter radiated spurious emissions tests were performed with the EUT transmitting in 1 Mbps.
* Proprietary: Transmitter radiated spurious emissions tests were performed with the EUT transmitting with a bit rate of 2 Mbps.
* MI 10.66 MHz: Transmitter radiated spurious emissions tests were performed with the EUT transmitting in the single channel configuration supported by this radio.
TESTED SIMULTANEOUS TRANSMISSION MODES:
* Co-Location mode Bluetooth, SRD 10.66 MHz: with the EUT configured to simultaneously transmit two signals at maximum output power: Bluetooth Low Energy in 1 Mbps mode, MI 10.66 MHz.
* Co-Location mode Proximity, SRD 10.66 MHz: with the EUT configured to simultaneously transmit two signals at maximum output power: Proprietary protocol 2.4 GHz in 2 Mbps mode, MI 10.66 MHz.

RADIATED MEASUREMENTS:
All radiated tests were performed in a semi-anechoic chamber. The measurement antenna is situated at a distance of 3 m (Loop antenna for the range between 9 kHz to 30 MHz. The measurement antenna (Bilog antenna for the range between 30 MHz to 1000 MHz and 1 GHz-17 GHz Double ridge horn antenna) is situated at a distance of 3 m and at a distance of 1.5 m for the frequency range 17 GHz-26 GHz (17 GHz-40 GHz horn antenna).
For radiated emissions in the range 17 GHz-26 GHz that is performed at a distance closer than the specified distance, an inverse proportionality factor of 20 dB per decade is used to normalize the measured data for determining compliance.
The equipment under test was set up on a non-conductive platform above the ground plane and the situation and orientation was varied to find the maximum radiated emission. It was also rotated 360º and the antenna height (Bilog antenna and Double ridge horn antenna) was varied from 1 to 4 meters to find the maximum radiated emission.
Measurements were made in both horizontal and vertical planes of polarization.

Radiated Emissions
Limits
Radiated emissions which fall in the restricted bands, as defined in §15.205(a), appearing outside of the band 13.110 MHz - 14.010 MHz band must also comply with the radiated emission limits specified in §15.209(a) (see §15.205(c) / RSS-Gen):
Frequency Range (MHz)
0.009-0.490 0.490-1.705 1.705 - 30.0
30 - 88 88 - 216 216 - 960 960 - 40000

Field strength (dBµV/m) 29.54 40 43.5 46 54
Measurement distance (m)
300 30 30 3 3 3 3
The emission limits shown in the above table are based on measurements employing CISPR quasi-peak detector except for the frequency bands 9-90 kHz, 110-490 kHz and above 1000 MHz. Radiated emission limits in these three bands are based on measurements employing an average detector.
For average radiated emission measurements above 1000 MHz, there is also a limit corresponding to 20 dB above the indicated values in the table is specified when measuring with peak detector function.
RSS-247. Attenuation below the general field strength limits specified in RSS-Gen is not required.
RESULTS:
The situation and orientation was varied to find the maximum radiated emission. It was also rotated 360º and the antenna height was varied from 1 to 4 meters to find the maximum radiated emission.
Measurements were made in both horizontal and vertical planes of polarization.
All tests were performed in a semi-anechoic chamber at a distance of 3 m for the frequency range 30 MHz-17 GHz and at distance of 1m for the frequency range 17 GHz-26 GHz.
The field strength is calculated by adding correction factor to the measured level from the spectrum analyzer. This correction factor includes antenna factor, cable loss and pre-amplifiers gain.
Test performed on the following worst-cases in all relevant tests channels.
