5.4 Waveform Outputs (MD2 Only)
Analogue Zero crosser, 3.5V full scale per channel (forward and
reverse). Conversion factor automatically adjusted to give
full scale outputs at ±0.1% (±10%) of probe frequency (e.g.
±8kHz for VP8)
Digital Data formatted to interface with Printa II or Recorder
software running on compatible computer. Conversion
factors automatically set as per analogue outputs.
CAL Function Automatic sequence of CAL levels set to ±0.05% (±10%)
and ±0.1% (±10%) of probe frequency (e.g. ±4kHz & ±8kHz
for VP8) with zero baseline at start and end of sequence.
