November 4, 1999 To: Ms. Linda Elliott Federal Communication Commission Equipment Approval Services P.O. Box 358315 Pittsburgh, PA 15251-5315 Subject: FCC Part 15 Class B approval of our Windows-based Terminal model WT3720SE Dear Ms. Elliott: We would like to submit our new Windows-based Terminal model WT3720SE to obtain FCC part 15 class B approval under FCC ID DYDWT3720. The Radiated and Line Conductive measurements were performed in accordance with EN55022 Class B. This model is identical to our approved model WT2715SE (DYDWINTERM2700), except for the logic board. The logic board is the same as that used in our approved model WT3320SE (DYDWT3320). With this letter I have provided all the necessary documentation electronically and attached the radiated and conducted setup drawings. All the test equipment information has been included as part of the radiated and conducted test report. Please note that the Anti-Drug letter was submitted to you during the original investigation of our model WT2300 (FCC ID DYDWT2300).

November 4, 1999 WYSE Technology EN 55022-B Test Record for Window Based Terminal Model Number: WT3720SE Tests performed by WYSE Technology 3471 N. First Street, San Jose, CA Test completed: October 21, 1999 Test Engineer: Benton Ng Approved by: Masood Abrishamcar October 21, 1999 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 October 21, 1999 on the WYSE WINTERM model: WT3720SE. 1.2 Purpose Testing was performed to evaluate the emissions performance of the WT3720SE with respect to EN 55022 Class B. 1.3 Summary The Power Adapter WT3720SE was found to be compliant to EN 55022 Class B Emission Requirements. 1.4Testing Requirements Testing was performed using procedures and criteria contained in EN 55022. 2.0 TEST ENVIRONMENT 2.1Test Sample Description WT3720SE is designed to communicate with a host system via Twisted 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 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 screen room is filed at WYSE Regulatory Engineering Department. The Screen Room is located at 3471 N. First Street, San Jose, California, USA. October 21, 1999 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 was used for frequency range 30MHz - 2 GHz. The frequency range was 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. 3.0 TEST RESULTS 3.1Test Description CISPR Publication 22:1985, 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. 3.3Test Procedure For radiated emissions testing, the equipment is installed on a 0.8 meter high non-conductive turntable 10 meter 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. October 21, 1999 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. 3.4Test Results A comparison of the measured data with the Class B limit of CISPR shows that Power Adapter WT3720SE was 2.30 dB below the limits at the worst case frequency of 179.99 MHz in a Vertical Polarization. 3.5 Product Specification Model: WT3720SE (Logic Board P/N 991336-01 Rev.
