The standard for emitting electromagnetic wave
As DIA:CONN P8 is manufactured to be used in the designated electromagnetic environment, it is used under the environment as below.
Test Name | Compliance Level | Electromagnetic Environment – Guidelines |

RF emissions
CISPR 11
Group 1
As DIA:CONN P8 uses RF energy only for the inner function, the RF emission is very low.
There is little possibility of interfering with any adjacent electronic device.
RF emission

Class B
DIA:CONN P8 can be used in all living or other facilities directly conncted to a public power supply with low voltage,
which usually offers electricity to the home building.

To reach the level of tolerance test, if needed, the distance between the transmission antenna and the ME device or ME system may be decreased to 1m. The test distance of 1m can be accepted by IEC 61000-4-3. |
a) Some services include only uplink frequency. b) Carrier wave should be modulated using square wave signal with 50% duty cycle. c) As an alternative for FM modulation, the carrier wave, can modulate the pulse using a 50% duty square wave signal at 18Hz. This does not mean the real modulation but is the worst case. |
