It is a battery operated transceiver hardware / software architecture which is able to support Walk By, Drive By, and Fixed Base 2-Watt operation. Manufacturer Information: Sensus Metering Systems, Inc. 400 Perimeter Park Drive, Suite K Morrisville, NC 27560 Test Sample Serial Numbers: 023001069 (Radiated), ACS #4 (conducted) Test Sample Condition: The test samples were provided in good working order with no visible defects. 1.3 Test Methodology 1.3.1 Test Configurations and Justification For RF conducted measurements, the GFL2 was modified with an external RF connector to the PCB. The GFL2 utilizes a non-detachable antenna for normal operation but for RF conducted testing the antennas were disconnected and a 50-Ohm test cable soldered (with the appropriate ground connection) to the PCB. The GFL2 operates using various modulation formats/modes all of which were evaluated and worst case data presented where applicable. 1.3.2 In-Band Testing Methodology For testing in accordance with 47 CFR 2.1046-2.1057, OET/Lab recommends that the following be used to select test frequencies for licensed devices: Frequency range over which device operates Number of frequencies Location in the range of operation 1 MHz or less 1 Middle 1 to 10 MHz 2 1 near top and 1 near bottom 10 to 100 MHz 3 1 near top, 1 near middle and 1 near bottom Model: GFL2 FCC ID: SDBGFL2 IC: 2220A-GFL2 ACS Report: 10-0172.W06.11.A Advanced Compliance Solutions Page 4 The GFL2 module is designed to operate in multiple bands under the requirements of CFR 47 Parts 24, 90, and 101. The following is a list of the frequency bands of operation sorted based on the FCC rule parts in which the band is associated. CFR Title 47 Rule Part Frequency Band of Operation (MHz) 24D 901.0 - 902.0 24D 930.0 - 931.0 24D 940.0 - 941.0 90 896.0 - 901.0 90 935.0 - 940.0 101 928.85 - 929.0 101 932.0 - 932.5 101 941.0 - 941.5 101 959.85 - 960.0 Based on the requirements set forth in accordance 47 CFR 2.1046-2.1057 as stated above, the methodology in selecting the places to test in the available bands of operation is outlined in the following table. CFR Title 47 Rule Part Frequency Band of Operation (MHz) Location in the Range of Operation 90 896.0 - 901.0 24D 901.0 - 902.0 1 near top and 1 near bottom 101 928.85 - 929.0 Middle 24D 930.0 - 931.0 Middle 101 932.0 - 932.5 Middle 90 935.0 - 940.0 24D 940.0 - 941.0 101 941.0 - 941.5 1 near top and 1 near bottom 101 959.85 - 960.0 Middle The data provided in this report is sorted based on the rule part. 1.4 Emission Designators The GFL2 transceiver produces (8) distinct modulation formats. The emissions designators for the nine modulation types used by the GFL2 transceiver are as follows: EMISSIONS DESIGNATORS: Normal Mode: 9K60F2D (7-FSK) Double Density Mode: 9K60F2D (13-FSK) C&I Mode: 4K80F2D (7-FSK) Priority Mode: 4K80F2D (13-FSK) Boost Mode: 1K10F2D (7-FSK) MPass Mode (5K): 5K90F1D (2-GFSK) MPass Mode (10K): 11K8F1D (2-GFSK) MPass Mode (12.5K): 14K8F1D (2-GFSK) Model: GFL2 FCC ID: SDBGFL2 IC: 2220A-GFL2 ACS Report: 10-0172.W06.11.A Advanced Compliance Solutions Page 5 2.0 TEST FACILITIES 2.1 Location The radiated and conducted emissions test sites are located at th…
