Peak Power Meter HP 8900C With Peak Power Sensor HP 84811A TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of TIMCO ENGINEERING, INC. Shielded interface cables were used in all cases except for cables connecting to the telephone line and the power cords. A test program was run which simulated a normal data transmission on a network. POWER LINE CONDUCTED INTERFERENCE: The procedure used was ANSI STAN- DARD C63.4-1992 using a 50uH LISN. Both lines were observed. The bandwidth of the spectrum analyzer was 10kHz with an appro- priate sweep speed. The ambient temperature of the UUT was 78oF with a humidity of 48%. BANDWIDTH 6.0dB: The measurements were made with the spectrum analyz- er's resolution bandwidth(RBW)=100KHz and the video bandwidth(VBW) =300KHz and the span set as shown on plot. POWER OUTPUT: The RF power output was measured at the antenna feed point by removing the permanent antenna and connecting the UUT to a peak power meter, HP Model No. 8900C. ANTENNA CONDUCTED EMISSIONS: The RBW=100KHz, VBW > or = RBW and the spectrum was scanned from 30MHz to the 10th Harmonic of the fundamen- tal. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a prese- lector. The bandwidth(RBW) of the spectrum analyzer was 100kHz up to 1GHz and 1.0MHz above 1GHz with an appropriate sweep speed. The VBW above 1.0GHz was = 1.0MHz. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The ambient temperature of the UUT was 78oF with a humidity of 72%. PAGE #: 2 APPLICANT: HANCHANG CORPORATION FCC ID: GH3HD-800 TEST PROCEDURE (Continued) 15.247(d)POWER SPECTRAL DENSITY.The peak within the pass band was located with a RBW OF 3KHz and a span of 2.0MHz, slightly greater than the 6dB bandwidth, then span was centered on the display and the span is reduced to 900KHz and the sweep time set to 300 seconds. Since the spectral line spacing could not be resolved, the spectral density was measured using the noise power density and adding the correction of 35dB. This response is then plotted. 15.247(e): PROCESSING GAIN, This gain is supplied by the manufacturer of the UUT. 2.1033(b)(4) ANTENNA AND GROUND SYSTEM: This unit…
