A sample calculation, configuration photographs and data tables of the emissions are included.

  • Page 8: Requirements And Test Results, Part 15, Subpart D

    PCS device that includes digital circuitry not directly associated with the radio transmitter also is subject to the requirements for unintentional radiators in Subpart B. The DT-620 tunes up to 1930 MHz. Therefore, in accordance with §15.33 (b) (1), the EUT was tested from 30 MHz to 10 GHz.
  • Page 9 0.45 to 30 48.0 Measurement Data: The DT-620 does not connect to the AC mains, however, the battery charger does connect to the AC mains; therefore, the conducted emissions testing was performed with the handset in the charger. Company: Ericsson...

The DT-620 tunes up to 1930 MHz; therefore, in accordance with §15.33 (b) (1), the EUT was tested from 30 MHz to 19.3 GHz, and in accordance with §15.31(m) the EUT was tuned with the transmitter at a low channel and an upper channel.
  • Page 14 Transmissions shall be continuous in every time and spectrum window during the frame period defined for the device. The DT-620 was tested at Ericsson Inc. See Appendix B for the test results. 3.2.17 Frequency Stability §15.323 (f) The frequency stability of the carrier frequency of the intentional radiator shall be maintained within +/-10 ppm over 1 hour or the interval between channel access monitoring, whichever is shorter.
