CFR › Title 47 › Chapter I › Subchapter B › Part 24 › Subpart D › Section 24.135 47 CFR 24.135 - Frequency stability.
§ 24.135
The frequency stability of the transmitter shall be maintained within ±0.0001 percent (±1 ppm) of the center frequency over a temperature variation of −30 °Celsius to 50 °Celsius at normal supply voltage, and over a variation in the primary supply voltage of 85 percent to 115 percent of the rated supply voltage at a temperature of 20 °Celsius.
For battery operated equipment, the equipment tests shall be performed using a new battery without any further requirement to vary supply voltage.
It is acceptable for a transmitter to meet this frequency stability requirement over a narrower temperature range provided the transmitter ceases to function before it exceeds these frequency stability limits.
§ 24.135 Frequency stability.
(a) The frequency stability of the transmitter shall be maintained within ±0.0001 percent (±1 ppm) of the center frequency over a temperature variation of −30 °Celsius to 50 °Celsius at normal supply voltage, and over a variation in the primary supply voltage of 85 percent to 115 percent of the rated supply voltage at a temperature of 20 °Celsius. (b) For battery operated equipment, the equipment tests shall be performed using a new battery without any further requirement to vary supply voltage. (c) It is acceptable for a transmitter to meet this frequency stability requirement over a narrower temperature range provided the transmitter ceases to function before it exceeds these frequency stability limits.
