$2.995(a)(b)(d) Frequency_stability: 90.213 Temperature and voltage tests were performed to verify that the frequency remains within the .00025%, 2.5 ppm specification limit. The test was conducted as follows: The transmitter was placed in the temperature chamber at 25 degrees C and allowed to stabilize for one hour. The transmitter was keyed ON for one minute during which four frequency readings were recorded at 15 second intervals. The worse case number was taken for temperature plotting. The assigned channel frequency was considered to be the reference frequency. The temperature was then reduced to -30 degrees C after which the transmitter was again allowed to stabi- lize for one hour. The transmitter was keyed ON for one minute, and again frequency readings were noted at 15 second intervals. The worst case number was recorded for temperature plotting. This procedure was repeated in 10 degree increments up to + 50 degrees C. Readings were also taken at plus & minus 15% of the supply vol- tage of 13.6VDC. MEASUREMENT DATA: Assigned Frequency (Ref.
