U-transceiver Characteristics
Note:
1) Test conditions: 1.3 Vpp antisemetric sine wave as input on AIN/BIN with long range (low, critical range).
2)
Interpretation and test conditions: The sum of noise and total harmonic distortion,
weighted with a low pass filter 0 to 80 kHz, is at least 65 dB below the signal for an
evenly distributed but otherwise random sequence of + 3, + 1, – 1, – 3.
3)
The signal amplitude measured over a period of 1 min. varies less than 1%.
4)
The percentage of the “1“-values in the PDM-signal.
