Ref. No.: LR500190908D 3.2.9 Frequency Stability Definition: - Modulation limiting refers to the transmitter circuits ability to limit the transmitter from producing deviations due to modulation in excess of a rated system deviation. Specification : 47 CFR 2.1055 Test method : ANSI/TIA/EIA-603-C-2004 Measurement Procedure: The frequency stability of the transmitter is measured by: a) Temperature: The temperature is varied from -30℃ to +60℃ using an environmental chamber. b) Primary Supply Voltage: The primary supply voltage is varied from 85% to 115% of the voltage normally at the input to the device or at the power supply terminals if cables are not normally supplied. Specification- The frequency stability shall be sufficient to ensure that the fundamental emission stays within the authorized frequency block. The frequency stability of the transmitter shall be maintained within ±0.00025(±2.5ppm) of the center frequency. Time Period and Procedure: 1. The carrier frequency of the transmitter and the individual oscillators is measured at room temperature (25℃ to 27℃ to provide a reference). 2. The equipment is subjected to an overnight “soak” at -30℃ without power applied. 3. After the overnight “soak” at 30℃(usually 14-16 hours), the equipment is turned on in a “standby” condition for one minute before applying power to the transmitter. Measurement of the carrier frequency of the transmitter and the individual oscillators is made within a three minute interval after applying power to the transmitter. 4. Frequency measurements are made at 10℃ interval up to room temperature. At least a period of one and one half-hour is provided to allow stabilization of the equipment at each temperature level. 5. Again the transmitter carrier frequency and the individual oscillators is measured at room temperature to begin measurement of the upper temperature levels. 6. Frequency measurements are at 10 intervals starting at -30℃ up to +60℃ allowing at least two hours at each temperature for stabilization. In all measurements the frequency is measured within three minutes after re- applying power to the transmitter. 7. The artificial load is mounted external to the temperature chamber. NOTE: The EUT is tested down to the battery endpoint. Measurement Data: - Refer to the Appendix II. Copyright ○ c 2011, LTA Co., Ltd. Page 17 of 29
