Exhibit 6A _ACLAP4U01 Page. 4 Description of Instrumentation and calculation (1) Measurement equipment a. Field Strength Meter : Electro—Metrics Model EMC—50 Bandwidth Setting _: 1 MHz Detector Function _: Linear Average Detection b. Receiving Antenna _: Electro—Metrics Model RGA—180 Frequency Range :1 — 18 GHz _c. Microwave Survey Meter : Narda Model 8110B (2) Test Condition _a. Antenna Height Variation : 1.0 — 1.5 m b. Distance of Antenna to Test unit : 3.0 m c. Test Unit Height : 1.0 m (3) Calculation Formula Field Strength at 3 m (dBuV/m) = Receiver Reading + Antenna Factor + Cable Loss (dBuV) (dB/m) (dB) ~Field Strength at 300m (uV/m) _ _Field Strength at 3 m (dBuV/m) = K * 10 20 K: Conversion Factor for 3 m to 300 m Frequency Antenna Factor| Cable Loss Conv. Factor (MHz) (dB/m) (dB) K 2400 29 0.7 0.0061 Fundamental 29.3 0.7 0.0062 2500 29.5 0.7 0.0063 4900 33.4 0.9 0.01 7350 36.5 1.2 0.01 9800 38.2 1.4 0.01 Example : 2nd Harmonics Receiver Reading =20 dB @ 3 m 20 + 33.4 + 0.9 FIS=0.01 * 10 20 = 5.19 (uV/m) @300 m
