I have revised the cover letter and conducted test setup drawing by changing the monitor to a 19" HP monitor. I've uploaded this letter and test setup drawing, along with the new conducted data, front and back photos of the conducted test, three photos of the interior of the power adapter, and photo of the solder side of the main board.

This external power adapter is part of EUT so internal photos are required. Question #2:Acknowledged Question #3:The peripherals used during final compliance tests shall be un-modified and readily available from retail stores. The printer that you used has FCC DoC / FCC ID number compliance information on it. If you modify the compliance product, then you are the responsible party for product compliance. Because you have no control on which printer that the end-user will be used to connect to the EUT, the modification you made on the printer to reduce the emission level is not acceptable. Please redo Conducted emission tests with un- modified peripherals.

Here's our reply to your "Questions" below" #1: We purchase external power adapter from the out side vendors. These power adapter has already approved for Safety and CE. We you still think there a need to include external power adapter board in the report. Please let me know. There no problem. #2: I will go ahead and provide you with the solder side of the main board and send it to you. #3: We regard the printer as a peripheral equipment only. We do not ship the printer with our product; and we have no control of what the customers use for their printers. Adding the ferrite on the power adapter for the printer eliminates the possibility of adding the emission to the true measurement of the EUT (our product). But if you still think that it is not permitted, we can do another conducted test, and send you a new set of data. There's no problem, excepted that it may delay the processing time for our application. Please call or email me with your reply as soon as you can. Thank you very much for you quick attention.

June 6, 2001 WYSE Technology EN 55022-B Test Record for Window Based Terminal Model Number: T20 Tests performed by WYSE Technology 3471 N. First Street, San Jose, CA Test completed: May 30, 2001 Test Engineer: Harinder Phul Approved by: Jimmy Nguyen June 6, 2001 1.0INTRODUCTION 1.1 Scope This record is intended to document conformance with the EMC Directive (89/336/EEC) and details the results of testing performed on June 6, 2001 on the model T20 . 1.2 Purpose Testing was performed to evaluate the emissions performance of the T20 with respect to EN 55022 Class B . 1.3 Summary The Windows Terminal T20 was found to be compliant to EN 55022 Class B Emission Requirements. 1.4 Testing Requirements Testing was performed using procedures and criteria contained in EN 55022 . 2.0TEST ENVIRONMENT 2.1 Test Sample Description T20 is designed to communicate with a host system via Twiste d Pair LAN interface on NT Windows Server. Test Software The software used during the test was a continuous loop batch file on Windows NT station. The program creates an entire page of “H”’s and writes the entire page to the screen, and it also prints to the serial and parallel devices as used in the test setup. The cables were moved around to find the maximum emission from the EUT. 2.2 Test Facilities 2.2.1 Emissions Test Site Radiated emissions testing was performed on a weather protected Open Area Test Site. The description of OATS is filed at the WYSE Regulatory Engineering Department. The OATS is located at 3471 N. First Street, San Jose, California, USA. Conducted emission testing was performed inside a shielded enclosure ( Screen Room ) in the WYSE RFI laboratory. The description of the screen room is filed at WYSE Regulatory Engineering Department. The Screen Room is located at 3471 N. First Street, San Jose, California, USA. June 6, 2001 2.3 Test Equipment The following are the list of equipment used during the radiation and conducted testing. Radiated: HP Receiver model 84560A (RES BW: 30 KHz-100KHz, VBW: 10KHz – 30KHz) Conducted: HP 85650A Quasi-Peak Adapter HP 8566B Spectrum Analyzer (RES BW: 30KHz –100KHz, VBW: 10KHz – 30KHz) SETUP: In accordance with WYSE Technology test procedure. PROCEDURE: Biconilog antenna w as used for frequency range 30MHz - 2 GHz. The frequency range w as checked for signals strength. The antenna was then raised and lowered for final maximization. The frequency range was checked with antennas in the horizontal and vertical polarization. 3.0TEST RESULTS 3.1 Test Description CISPR Publication 22:1997 , limits and methods of measurements of radio interface of information technology equipment, was the guiding document for the test. The product’s radiated emissions from 30 MHz to 1000 MHz and its power mains conducted emissions from 150 KHz to 30 MHz were measured. 3.2 Test Configuration The EUT was configured with a typical mix of available peripherals which fully configured all types of communications ports of the EUT and exercised it in a typical manner. 3.3 Test Procedure For radiated emissions testing, the equipment is installed on a 0.8 meter high non-conductive turntable 10 meters from the receiving antenna mast. The EUT is fully exercised during the test to maximize emissions. The receiving antenna is scanned over the height range of 1 to 4 meters is both polarities and the turntable is rotated with emissions level observed at each frequency. During the process the equipment configuration is also modified by moving the interconnecting cables to find the typical configuration that maximizes emissions at each frequency. The frequency range from 30 MHz to 1000 MHz is explored. Measurement data is compared to Class B limit. June 6, 2001 For conducted emissions testing the equipment is moved to a 0.8 meter high platform and the EUT and Configurations equipment are powered from a different LISNs. Both sides of the AC line are measured and the results compared to the Class B limit. 3.4 Test Results A comparison of the measured data with the Class B limit of CISPR shows that Windows Terminal T20 was 4.95 dB below the limits at the worst case frequency of 224.971365 MHz in a Vertical Polarization. 3.5 Product Specification Model: T20 (Logic Board P/N 961401-00, Rev. 3) Clock Circuit: U16 = MK1492-03, P/N 205565-50 Filters: 33 MHZ CLK Li ne: RP29 = 33 Ohm, P/N 371338-02; C45, C46, C47 = 15pF (not loaded) 14 MHZ CLK Li ne: R59 = 33 Ohm, P/N 370513-13; C44 = 15pF (not loaded) 48 MHZ CLK Li ne: R60 = 33 Ohm, P/N 370513-13; C43= 15pF(not loaded) 24 MHZ ( Audio) CLK Line: R61 = 33 Ohm, P/N 370513-13; C42= 15pF (not loaded) U1 = GX1-300, P/N 20064-55 Power Filter U2 = CS5530A, P/N 205122-52 Filters: R4 = 33 Ohm, P/N 370513-13; C2 = 15pF (not loaded) R5 = 33 Ohm, P/N 370513-13; C3 = 15pF (not loaded) L21 = 22 μ H, P/N 410032-09 L20 = 44MTL, P/N 400021-04 L22 = 43MTL, P/N 400021-01 RP 1-7 = 75 Ohm, P/N 371338-12 June 6, 2001 Vide o Circuit: U2 = CS5530A, P/N 205122-52 Filters: L1 = 0.47 μ H, P/N 410038-02; C7, C10 = 22pF, P/N 320313-21 L2 = 0.47 μ H, P/N 410038-02; C6, C9 = 22pF, P/N 320313-21 L3 = 0.47 μ H, P/N 410038-02; C5, C8 = 22pF, P/N 320313-21 Termination: R8, R9, R10 = 75 Ohm, P/N 370508-85 Audio Circuit: U14 = LM4546, P/N 205123-53 Filters: C431 = 0.1 μ F, P/N 320338-24 L25, L26 = 50 Ohm, P/N 400040-03 Driving Transistor: Q3, Q4 = MMBT3904, P/N 270010-50 Ne twork: U3 = DP83815, P/N 205127-51 Filters: R67, R68 = 49.9 Ohm, P/N 370508-68 J10 = RJ45 Connector w/ transformer built in, P/N 563680-01 Filters: C37, C38, C39 = .1 uF, P/N 320338-24 R65, R66 = 54.9 Ohm, P/N 370508-72 R67, R68 = 49.9 Ohm, P/N 370508-68 G round Jumpe r Se tting: R165, R166 = 0 Ohm, P/N 370514-99 Radiated Emission Test 10M OATS WYSE Technology Inc. 3471 North 1st Street San Jose Ca 95134 Test Description : EUT: T20 Serial No. 9GV1A500022 Part No. 902021-01 File No. 053001#3 Test Type: EN55022 EN55022 FCC-A { } FCC-B { X } CISPR-A { } CISPR-B { X } PASS: X FAIL: Debug: Frequency Peak DelLim-Pk QP DelLim-QP Angle Hgt …
