MOSC6 module is designed to work as part of information measuring systems based on the VXI bus as a digital oscilloscope. The module is made in the form of a triple-width mezzanine, is mounted on a mezzanine carrier and connected to it via a local information highway.

MOSC6 is designed to convert instantaneous voltage values ​​of an electrical signal into a digital code, measure instantaneous voltage values, measure time intervals between two instantaneous voltage values ​​via two independent channels.

MOSC6 provides:

  • digital-to-analog conversion of the instantaneous voltage values ​​of the input signals through two channels with a given sampling rate and recording the received measurement information in the memory installed on the mezzanine;
  • setting the signal bias voltage for each channel, which is performed within the selected measurement range;
  • software setting of channel operation modes for direct current: “Open” (absence of separation capacitance at the input); “Closed” (presence at the input of the separation capacitance);
  • the ability to select a trigger on the rising or falling edge of the signal in the modes of internal and external launches;
  • the ability to select launch modes: program, internal, external;
