6. :Measurement

6－１． Measurement Condition

Unless otherwise sepecified ,the shandard range of atmospheric conditions for measurements and tests are as follows:

Ambient temperature:5℃ to 35 ℃ Relative humidity :45% to 85%

Air pressure :86Kpa to 106 Kpa

If there is doubt about the results, measurement shall be made within the following limits:

Ambient temperature:18℃ to 22 ℃ Relative humidity :60% to 70%

Air pressure :86Kpa to 106 Kpa

6－２． Measuring Circuit

6－3． Test Method

Input signal condition	Input level	80dBμ
	Frequency Deviation	±4.0 kHz
	Modulation Frequency	1.0 kHz
Demodulated 3dB Bandwidth	Input the above signal and sweep the carrier around 455 kHz, and find Out the maximum audio output frequency. Then sweep the carrier frequency again and find two frequencies, which are observed –3dB attenuation points from the maximum point. Higher frequency point is called (f1) and lower called (f2). (F1-455KHz) is defined as upper 3dB bandwidth and (455KHz-f2) defined as lower 3dB bandwidth.
Demodulate Output	Demodulated output shall be measured when carrier frequency is adjusted to 455KHz.
Demodulated Distortion Factor	Carrier frequency is adjusted to 455KHz.And distortion shall be measured with 1 kHz modulation frequency.
