It has internal rechargable NiCd batteries and can also operate from AC power (using an unusual power cord) or external DC from 6 V to 16 V. | |||
The external oscilloscope is assumed to have 10 horizontal divisions and 6 vertical divisions. Tektronix says it is compatible with any oscilloscope having 0.5 V/div horizontal deflection factor and 1.2 V full screen vertical deflection. | The external oscilloscope is assumed to have 10 horizontal divisions and 6 vertical divisions.
