7.8              Frequency Stability / Temperature Variation
Test Overview and Limit

Frequency stability testing is performed in accordance with the guidelines of ANSI/TIA-603-E-2016. The frequency
stability of the transmitter is measured by:

a.)       Temperature: The temperature is varied from -30°C to +50°C in 10°C increments using an environmental
          chamber.

b.)       Primary Supply Voltage: The primary supply voltage is varied from 85% to 115% of the nominal value for
          non hand-carried battery and AC powered equipment. For hand-carried, battery-powered equipment, primary
          supply voltage is reduced to the battery operating end point which shall be specified by the manufacturer.

For Part 22, the frequency stability of the transmitter shall be maintained within ±0.00025% (±2.5 ppm) of
the center frequency. For Part 24, Part 27, the frequency stability shall be sufficient to ensure that the
fundamental emission stays within the authorized frequency block.

Test Procedure Used

ANSI/TIA-603-E-2016

Test Settings

      1. The carrier frequency of the transmitter is measured at room temperature (20°C to provide a reference).
      2. The equipment is turned on in a “standby” condition for fifteen minutes before applying power to the
         transmitter. Measurement of the carrier frequency of the transmitter is made within one minute after
         applying power to the transmitter.
      3. Frequency measurements are made at 10°C intervals ranging from -30°C to +50°C. A period of at least
         one half-hour is provided to allow stabilization of the equipment at each temperature level.

Test Setup

The EUT was connected via an RF cable to a spectrum analyzer with the EUT placed inside an environmental
chamber.

Test Notes

None

Note:

Based on the results of the frequency stability test at the center channel the frequency deviation results measured
are very small. As such it is determined that the channels at the band edge would remain in-band when the
maximum measured frequency deviation noted during the frequency stability tests is applied. Therefore the
device is determined to remain operating in band over the temperature and voltage range as tested.

Note:

Based on the results of the frequency stability test at the center channel the frequency deviation results measured
are very small. As such it is determined that the channels at the band edge would remain in-band when the
maximum measured frequency deviation noted during the frequency stability tests is applied. Therefore the device
is determined to remain operating in band over the temperature and voltage range as tested.

Note:

Based on the results of the frequency stability test at the center channel the frequency deviation results measured
are very small. As such it is determined that the channels at the band edge would remain in-band when the
maximum measured frequency deviation noted during the frequency stability tests is applied. Therefore the
device is determined to remain operating in band over the temperature and voltage range as tested.

Note:

Based on the results of the frequency stability test at the center channel the frequency deviation results measured
are very small. As such it is determined that the channels at the band edge would remain in-band when the
maximum measured frequency deviation noted during the frequency stability tests is applied. Therefore the device
is determined to remain operating in band over the temperature and voltage range as tested.
