Test Report 3/18 Chapter 1 Introduction Description ofEUT : These products are professionally designed wireless microphone and receiver system made—up of diverse circuit. It can receive one frequency between 174 MHz and 216 MHz. This microphone is worn by a performer and other participants in a program, filming . reporting ... etc. Connection ofEUT : (1)Connect the EUT‘s audio output to guitar amplifier by an audio cable . (2)Plug the adapter into the EUT, (3)Pull out the antenna vertically . Test method : There are three EUT‘s tested which are operatd at 174.1, 194.6, 214 MHz separately. Turn on the receiver and the speaker. There is a signal generator connected with a field probe , which can transmit the receiving frequency , put near the EUT . The test data also showed three EUT‘s emission . (If the emission is close to the ambience, the resolution BW and view resolution will be reduced and the data will be recorded by detection of maximum hold peak mode.) Statement oftransition provision for compliance with the rules The EUT receives the signal which only send from the wireless microphone, The EUT won‘t be influenced by the transition provision , it will be continue to comply with the regulations of the FCC Part 15 . ( The relative wireless microphone FCC ID :H38VXM—198TS). The testing configuration of test setup is showing in the next page.

Test Report 6718 Chapter 2 Conducted emission test Test condition and set up : All the equipment is placed and setup according to the ANSI C€63.4 — 1992 . The EUT is assembled on a wooden table which is 80 cm high , is placed 40 cm from the back—wall which is a vertical conducting plane . One LISN is for EUT ,the other LISN is for support equipment. They are all placed on the conductive ground .The EUT‘s LISN is connected to a line switch box for selecting L1 or L2 .then connect to a preamplifier and spectrum. The spectrum seans from 450KHz to 30MHz . Conducted emission levels are detected at max. peak mode . Butif the max. peak mode failed ,it will be measured by CISPR‘s quasi—peak detection mode . While testing, there is a worst—emission plot printed at peak detection mode .and there are more than 6 highest emissions relative to limit recorded. The plot is kept as the original data, not included in test report .

Test Report 8/18 Chapter 3 Radiated emission test Test condition and set up : Pretest : Prior to the final test (OATS test) ,the EUT is placed in a shielded enclosure ,GTEM, and scan from 30MHz to 1GHz.This is done to ensure the radiation exactly emits form the EUT. Final test : Final radiation measurements is made on a 3 — meter, open—field test site. The EUT is placed on a nonconductive table which is 0.8 m height, the top surface is 1.0 x 1.5 meter. All the placement is according to ANSI C63.4 — 1992. The spectrum is examined from 30 MHz to 1000 MHz measured by HP spectrum. The EMCO whole range Antenna is used to measure frequency from 30 MHz to 1GHz.The final test is used the spectrum HP 8594EM . Measure more than six top marked frequencies generated form pretest by computer step by step at each frequency . The EUT is rotated 360 degrees, and antenna is raised and lowered from 1 to 4 meter to find the maximum emission levels. The antenna is used with both horizontal and vertical polarization. Appropriated preamplifier which is made by TRC is used for improving sensitivity and precautions is taken to avoid overloading .The spectrum analyzer‘s 6dB bandwidth is set to 120 K Hz , and the EUT is measured at quasi—peak mode. If the emission is close to the frequency band of ambience ,the data will be rechecked by the tester and the corrected data will be written in the test data sheet. If the emission is just within the ambience .the data from GTEM will be taken as the final data.
