NOTES: 4. Unless otherwise noted, the analog input is a 0-dBm0, 1020-Hz sine wave, where 0 dBm0 is defined as the zero-reference point of
the channel under test. This corresponds to an analog signal input of 1.064 Vrms or an output of 1.503 Vrms.
5. The input amplifier is set for noninverting unity gain. The digital input is a PCM bit stream generated by passing a 0-dBm0, 1020-Hz
sine wave through an ideal encoder.
6. Receive output is measured single ended in the maximum-gain configuration. To set the output amplifier for maximum gain, GSR is
connected to PWRO – and the output is taken at PWRO +. All output levels are (sin x)/x corrected.
