Electrical and mechanical drawings are included in the Operation and Instruction manual as supplied in Exhibit XIII. T ESTING ALGORITHM: The EUT was driven with the highest input signal level permitted in both the forward and reverse signal path directions. The worst case emissions are recorded in the data tables. C ONDUCTED EMISSION TESTING: The EUT was placed on a 0.8 meter high, 1 X 1.5 meter non-conductive table. Power was provided to the EUT through a LISN bonded to a 3 X 2 meter ground plane. The LISN and peripherals were supplied power through a filtered AC power source. The output of the LISN was connected to the input of the receiver and emissions in the range 450kHz to 30 MHz were measured. The measurements were recorded using the quasi-peak values, and the resolution bandwidth during testing was 9kHz. All data for conducted emissions is found in Exhibit VI. R ADIATED EMISSIONS: SPURIOUS EMISSIONS TESTING The EUT was tested at a distance of 3 meters. The emissions were maximized by rotating the table and raising/lowering the antenna mounted on a 4 meter mast. Cable and peripheral positions were also varied to produce maximum emissions. Both horizontal and vertical field components were measured. The output of the antenna was connected to the input of the receiver and emissions were measured in the range 30MHz to 8.5 GHz. The measured values up to 1GHz with a resolution bandwidth of 120KHz are quasi-peak readings made at 3 meters. Emissions from 1 GHz to 8.5 GHz were measured with a resolution bandwidth of 1 MHz and placed in the average detector mode. All data for radiated spurious emissions is found in Exhibit VII. R ADIATED SPURIOUS EMISSION ANTENNA PORT TESTING: The EUT was tested near the spectrum analyzer and source signal generators with the shortest available length cables to insure correct data collection. The Forward and Reverse outputs of the EUT were connected to the EMI receiver input port and the emissions were measured as shown in Exhibit VII. The test was then repeated with the receiver input connected first to the Forward Channel input port followed by measurements from the Reverse Channel input port. Client: Aero Comm, Inc.

The output of the EUT was connected to the receiver and the emissions were measured as shown in Exhibit VIII.

The Forward and Reverse outputs of the EUT were connected to the EMI receiver input port and the emissions were measured as shown in Exhibit VII. The test was then repeated with the receiver input connected first to the Forward Channel input port followed by measurements from the Reverse Channel input port. Client: Aero Comm, Inc. Report No.: 9200-01 FCC ID: KJA504830225Issue Date: August 30, 1999 Model: 502890-RBA-800MHz Page 7 of 39 INTERMODULATION DISTORTION AND EMISSIONS MASK TESTING: The EUT was tested by the use of 2 signal generators, 1 combiner, and 2 isolators in line with each signal generator. The output of the EUT was connected to the receiver and the emissions were measured as shown in Exhibit VIII. C ALCULATION OF DATA #1: RADIATED EMISSIONS - The antenna factors (including cable losses) of the biconical antennas were used along with the pre-amplifier gain, which were e…
