Depending on the setstandard the audio carriers are assigned various frequencies (seetable). After channel and frequency entry audio carrier 1 is alwaysset.Standard TT1 TT2 NicamB/G 5.5 MHz 5.74 MHz 5.85 MHzD/K 6.5 MHz 6.26 MHz 5.85 MHzI 6.0 MHz ----- 6.552 MHzM/N 4.5 MHz 4.72 MHz -----L AM 6.5 MHz ----- 5.85 MHzM1 (Japan) 4.5 MHz ----- -----In audio carrier measurement the signal spacing between audio andvideo carrier in dB is measured first, then the absolute audio carrierlevel in dBμV. During the measurement the speaker is mute. Aftercompletion of the measurement the modulation of the audio carrierlast measured can be heard.COMMAND OVERVIEW FOR “MEASURE TV AUDIO CARRIER FREQUENCY”[SUBC] Switch to audio carrier menu[1]...[2] Switch between TT1 and TT2 (see table)Audio carrier measurement while button is pressed[3] Switch to Nicam receptionExampleTo measure audio carrier level spacing and level of TT1:Press [SUBC],now press [1] and keep the button pressed.The LC display indicates the following values for app. 1 second:• Audio carrier level spacing - frequency: 5.5 MHz• Audio carrier - video carrier spacing: -13 dB• Operating mode: Analogue cable TV
