Notes
1. Oscillator ON; V
2. As note 1, but with oscillator OFF.
3. Related to the level of the LOW group frequency component, according to CEPT recommendations.
4. Related to the level of the fundamental frequency.
5. Oscillator must be running.
6. Values are referenced to the 10% and 90% levels of the relevant pulse amplitudes, with a total voltage swing from
