Spectrum's M2i-20xx Serie

M2i-40xx Series
14 Bit General Purpose Digitizers
Sample rates from 20 MS/s to 50 MS/s

The M2i-40xx Series of Spectrum has eight different models of these one to four channel 14-bit A/D-boards.
The sampling rates of these digitizers range from 20 MS/s up to 50 MS/s.
There are two models optimized for Radar applications.

Boards are available for the PCI/PCI-X and PCI Express bus.

M2i-40xx Series boards

  • up to 50 MS/s on four channels
  • simultaneous sampling on all channels
  • separate A/D converter and amplifier per channel
  • 6 input ranges: ±200 mV to ± 10 V
  • window, pulse width, re-arm, OR/AND trigger
  • programmable input-offset (± 200 %)
  • 128 MSample on-board memory (expandable up to 2 GSample)

 
On the M2i.40xx every channel has its own amplifier and A/D Converter. Each input channel can be adapted to a wide variety of signal sources. This is done by software selecting a matching input range, an input impedance and an individual input offset compensation. The user will easily find a matching solution from the six offered models. These versions are working with sampling rates of 20 MS/s or 50 MS/s and have one, two or four channels. They can also be updated to a multi-channel system using the synchronization option.

M2i-40x8 Boards - combined A/D plus digital data acquisition - RADAR optimized

  • simultaneous sampling on one 14-bit A/D channel and 16 digital channels
  • acquisition of angle encoder for azimuth and elevation angle
  • special marker mode for segmented acquisition
  • very short dead time between segments

Operating modes for the M2i.4028/4038:
Digital data can either be acquired fully in parallel or as a combination of counter input and parallel digital data. The acquisition mode can be programmed by software. When operating in continuous mode the analog and digital data is stored alternating in the on-board memory. For each 14-bit analog sample there is a corresponding 16-bit digital sample.
When operating in segmented marker mode there is one 16-bit digital sample stored at the end of each acquired segment holding the azimuth and elevation angle for this segment of analog data.
Acquisition can run at full sampling speed independent of the selected mode.
