from the standard value) will scale the amplitude of the D/A output by a certain offset. These bits are only effective when user programmable arbitrary
waveform is used.
Programming Information
IDT82P2288
The following setting lists the standard values of normal amplitude in different operating modes. Each step change (one increasing or decreasing
= 000100: Normal amplitude in T1 long haul LBO/-22.5 dB operating mode. Each step change scales about 25% offset.
= 001000: Normal amplitude in T1 long haul LBO/-15 dB operating mode. Each step change scales about 12.5% offset.
= 010001: Normal amplitude in T1 long haul LBO/-7.5 dB operating mode. Each step change scales about 6.25% offset.
= 110110: Normal amplitude in T1 0~133 ft, 133~266 ft, 266~399 ft, 399~533 ft, 533~655 ft, DS1 0 dB & J1 0~655 ft operating modes. Each step
change scales about 2% offset.
