Notes:
1. 0dBm0 is defined as the zero reference point of the channel under test (0TLP). This corresponds to an analog signal input of 1.064 Vrms
or an output of 1.503 Vrmst (
Law) dual 1.068 Vrmst or a output 1.516 Vrmst (A-Law)
2. Unity gain input amplifier : GSX is connected to VFXI, Signal input VFXI+; Maximum gain output amplifier: GSR is connected to PWRO,
output to PWRO+.
3. Noise free: DX PCM Code stable at 01010101.
