3. Test Specifications

3.1 Standards The following standards were applied for testing:FCC standard: 47 CFR FCC Part 15, Subpart B. Clause 15.107 and 15.109.

The EUT setup configuration please refer to the photo of test configuration in item.

3.2 Definition of Device Classification Unintentional radiator: A device which is not intended to emit RF energy by radiation or induction. Class A Digital Device: A digital device which is marketed for use in commercial or business environment. Class B Digital Device: A digital device which is marketed for use by the general public or in a residential environment. Note: A manufacturer may also qualify a device intended to be marketed in a commercial, business or industrial environment as a Class B digital device, and in fact is encouranged to do so, provided the device complies with the technical specifications for a Class B Digital Device. In the event that a particular type of device has been found to repeatedly cause harmful interference to radio communications, the Commission may classify such a digital device as a Class B Digital Device, regardless of its intended use.

3.3 EUT Operation Condition The EUT was supplied with DC 6V from adapter (120 Vac, 60 Hz) and was tested in normal operating mode.

The EUT was connected to power mains through a line impedance stabilization network (LISN), which provided 50 ohm coupling impedance for measuring instrument and the chassis ground was bounded to the horizontal ground plane of shielded room. The excess power cable between the EUT and the LISN was bundled. All connecting cables of EUT and peripherals were moved to find the maximum emission

5.1 Operating Environment

Temperature: 22 ℃ Atmospheric Pressure: 1023 hPa

Relative Humidity: 51 % Test Voltage: 120 Vac, 60 Hz

5.2 Test Setup and Procedure

(1) TTD-41T The figure below shows the test setup, which is utilized to make these measurements. The frequency spectrum from 30 MHz to 1000 MHz was investigated. The equipment under test was placed on the top of rotation table 0.8 meter above ground plane. The table was 360 degrees to determine the position of the highest radiation. EUT is set 3 meters from the EMI receiving antenna, which is mounted on a variable height mast. The antenna height is varied between one meter and four meters above ground to find the maximum value of the field strength. Both horizontal polarization and vertical polarization of the antenna are set to make the measurement. The bandwidth was setting on the EMI meter 120 kHz. The levels are quasi peak value readings.
