This 7-bit field defines the output level of tone generator 1 on channel 2. The output level
ranges from –12.1 to +0.5 dBm0 in 0.1 dBm0 intervals as shown in Table 19. A value of 0
in this field disables the tone generator.
The output level is calculated using the following formula.
Binary data for CR16- B7 to B1
= [(Output Level [dBm0]) + 12.2]*10
The following example shows how to program this field when the intended output level is –
5.8 dBm0;
Ex) [(Output Level [dBm0]) + 12.2]*10 = (–5.8 + 12.2)*10 = 64d = 1000000b
