Ref. No.: LR500111501C 3.2 Technical Characteristics Test 3.2.1 6 dB Bandwidth Procedure: The bandwidth at 6dB below the highest in-band spectral density was measured with a spectrum analyzer connected to the antenna terminal, while EUT is operating in transmission mode at the appropriate frequencies. After the trace being stable, Use the marker-to-peak function to set the marker to the peak of the emission. Use the marker-delta function to measure 6dB down one side of the emission. Reset the marker-delta function, and move the marker to the other side of the emission, until it is ( as close as possible to ) even with the reference marker level. The marker-delta reading at this point is the 6 dB bandwidth of the emission.

Ref. No.: LR500111501C 3.2.6 AC Conducted Emissions Procedure: AC power line conducted emissions from the EUT were measured according to the dictates of ANSI C63.4:2003. The conducted emissions are measured in the shielded room with a spectrum analyzer in peak hold. While the measurement, EUT had its hopping function disabled at the middle channels in line with Section 15.31(m). Emissions closest to the limit are measured in the quasi-peak mode (QP) with the tuned receiver using a bandwidth of 9 kHz. The emissions are maximized further by cable manipulation and Exerciser operation. The highest emissions relative to the limit are listed. Measurement Data: Not Applicable (-This device is operated by DC) - Refer to the next page. - No other emissions were detected at a level greater than 20dB below limit - It gave the worse case emissions Minimum Standard: FCC Part 15.207(a)/EN 55022 Frequency Range Conducted Limit (dBuV) (MHz) Quasi-Peak Average 0.15 ~ 0.5 66 to 56 * 56 to 46 * 0.5 ~ 5 56 46 5 ~ 30 60 50 * Note: The limits will decrease with the frequency logarithmically within 0.15MHz to 0.5MHz Copyright ○ c 2015, LTA Co., Ltd.
