Figure 9: Compensation level
The AES and SMPTE committees established the standard interface for transmission of AES/EBU
data on coaxial cable, sometimes referred to as AES3-ID. For this type of interface, the SD-7816B should
be used. The signal is bi-phase coded, transformer coupled and transmitted over a coaxial cable in a single
ended format. The signal level is 1.0 volts peak to peak with a source impedance of 75 ohms. The
interconnecting cable should also exhibit a nominal 75 ohms characteristic impedance. After all the
connections have been made, turn on the source signals units and the SD-7816B and measure, using an
oscilloscope, the signal level - directly on the input connectors of the SD-7816B as discribed above. Using
this value, set the DIP-switches according to Table 6. (Table 6 is based on the graph in figure 9 -
“Consumer format – 75 ohms, on BNCs”).
