So 3 points minimum? |

Whether you include the endpoints has no effect on the behavior, since none of the values 0.1, 0.5, 0.9 can occur exactly given the serial encoding scheme. |

1.1 states the absolute input voltage is +/-1.2V or 2.4V full scale. 1.5 states vertical resolution is 12-bits or 560uV. With this in mind, showing a 10MHz sine applied, 5ps resolution. Please explain the steps. |

(See attached screenshot.) Can you see the steps using our software? |

Yes, I can show it with your software but the difference is the source. We are seeing effects from my old Marconi 2024. Time to ditch it and go with the old HP8640B cavity. |
