An ESCO Technologies Company 30400 Solon Road Solon OH 44139 (440) 528-7200 ENGINEERING TEST REPORT RADIO-FREQUENCY EMISSIONS TEST REPORT TRANSIENT BEHAVIOR FOR HIGH READ-RATE GAS METER TRANSMITTING UNIT Model 2011-005X, Rev. C FCC ID: LLB11005X December 5, 2011 Report Prepared by Agency Certification Control Technician TEST REPORT INTRODUCTION The Hexagram Model 2011-005X transceiver is a “Meter Transmitting Unit” (MTU) designed to provide remote meter reading capability for a gas meter. The transceiver is self- powered and mounts directly on a gas meter. On board batteries provide power. The transmitter provides a very short, intermittent radio frequency transmission to send a remote reading of the meter to a data collector unit. A microprocessor provides timing, control and data processing functions. The internal antenna is inaccessible to the user and no external antenna is provided. Two identical units were used as a test subjects for this report. The unit used for each test is identified under the test procedure. This report presents the data obtained in support of an application for Certification under Part 90 of the FCC rules. MEASUREMENTS PERFORMED Occupied Bandwidth Page 2 TRANSIENT STABILITY The transient stability measurements indicate the variation in tuned frequency during the brief interval of time during the start of the transmission and at the end of the transmission. The Model 2011-005X transmitter was tested for transient frequency behavior using the test method of TIA/EIA-603-C. A block diagram of the test setup is seen in Fig. 2. A Hexagram model 9975G-WB receiver was used. The storage oscilloscope was triggered by the output of the RSSI output of the receiver. Appropriate delay was provided by the digital delay circuitry of the oscilloscope. The 1 kHz test signal was provided by the Marconi signal generator. The generator’s output control was used to insure that the test signal was at least 50 dB below the received signal level from the 2011-005X.

Frequency deviation during t 1 (10 ms duration after t on ) may be greater than ±12.5 kHz because the output power is less than 6 Watts. 2. Frequency deviation during t 2 (25 ms duration after t 1 ) must be less than ±6.25 kHz. 3. Frequency deviation after t 2 must be less than ±2.5 ppm, or ±1150 Hz at 460 MHz. 4. Frequency deviation during t 3 (10 ms duration after transmitter is turned off) may exceed ±12.5 kHz because output power is less than 6 Watts.

The transceiver is mounted within the meter enclosure. The transmitter provides a very short intermittent RF transmission to provide a remote reading of the meter. A microprocessor provides timing, control and data processing functions. The built in antenna is inaccessible to the user and no provision is made for an external antenna. The receiver can be used to request a meter reading or other options available in the system. Power Output: The EUT operates in the frequency range of (450 - 470) MHz. The first step in the measurement process was to measure the field strength of the fundamental frequency at the lowest, highest and middle operating frequency. These measurements are made in both the vertical and horizontal polarity. The maximum field strength is reported by raising and lowering the measuring antenna height between (1-4) meters and by rotating the EUT (360) degrees. The measurement distance is (3) meters. The field strength measurements continue as described above for up to the tenth harmonic of each fundamental frequency. Once the field strength of each signal is recorded, the EUT is replaced with a substitution antenna and signal generator. The substitution antenna is placed at the same height as the EUT had been. The combination of antenna and signal generator is then adjusted to reproduce the recorded field strength at each frequency. The ERP is then calculated by the following: ERP = PG - CL + ANT ERP = Effective Radiated Power (dBm) PG = Signal Generator Output (dBm) CL = Cable loss (dB) ANT = antenna gain (dBd) dBd = (antenna gain dBi) - (2.2 dB) The measurements were made using the standard ANSI/TIA-603-C-2004. Occupied Bandwidth: The occupied bandwidth was measured with the EUT set to low, medium and high transmit frequencies. The emissions mask used was that specified in Part 90.210 (d). Radiated Spurious Emissions: The radiated spurious emissions measurements were measured with the EUT set to low, medium and high transmit frequencies. Based upon the low output power of this device, all spurious and harmonic signals are limited to (-20) dBm. This is based upon the calculation stated in 90.210(d)(3). The field strength of the spurious emissions were measured in the same manner as the power output measurements and then the substitution method was used to establish the power level expressed in dBm. Frequency Stability vs. Supply Voltage: One of the internal batteries was disconnected and replaced with an external variable power supply. The frequency was measured at the normal battery voltage of (7.20) VDC and again with the external power supply adjusted to an (85%) level or (6.12) volts. This was repeated with the external DC voltage adjusted to (8.28) VDC. The maximum allowed deviation is (2.5) ppm or (1,150) Hz at (460) MHz. Aclara RF Systems FCC ID: LLB11005X Page 3 of 11 Frequency Stability vs. Temperature: The fundamental frequency was measured at an ambient temperature of (20) degrees C and recorded. The transmitter was then placed in a container along with a small section of dry ice and the environment was adjusted until a low temperature of (-30) degrees C was achieved. The transmitter was allowed to stabilize for (30) minutes at this temperature and then the frequency was again measured with a spectrum analyzer. The environment was allowed to warm to (-20) degrees C and the measurement process was repeated. The environment was moved to a maximum temperature of (+80) degrees C in (10) degree increments, allowed to stabilize for (30) minutes and the frequency was re-measured.
