Audio Block Input Signals and Test Conditions
Unless otherwise specified, the following conditions apply when each measurement is made.
1. Bus control condition : AUDIO. MUTE = ”0”, AUDIO. SW = ”1”, VOL. FIL = ”0” , SIF. SYS = ”00”,
IF. AGC. SW = ”1”
2. Input 4.5MHz, 90dBµ and CW at pin 54.
3. Enter an input signal from pin 51.

Test method
Measure the 1kHz component (V1 : mVrms)
at the pin 1 and calculate as follows :
AGMAX = 20Log (V1/500) [dB]
Measure the 1kHz component (V2 : mVrms)
at the pin 1 and calculate as follows :
ARANGE = 20Log (V1/V2) [dB]
Measure the 20kHz component (V3 : mVrms)
at the pin 1 and calculate as follows :
AF = 20Log (V3/V1) [dB]
Measure the 20kHz component (V4 : mVrms)
at the pin 1 and calculate as follows :
AMUTE = 20Log (V3/V4) [dB]
Measure the distortion of the 1kHz component at
the pin 1.
Measure the noise level (DIN AUDIO, V5 :
mVrms) at the pin 1 and calculate as follows :
ASN = 20Log (V1/V5) [dB]
Measure the 1kHz component (V6 : mVrms) at
the pin 1 and calculate as follows :
ACT = 20Log (V1/V6) [dB]
