The Spectrum M4x.44xx-x4 series PXIe digitizers are 14 and 16-bit digitizers with a maximum sample rate of 5ooMS/sec/channel. Depending on the model you have up to 4 channels.

All cards of the M4x.44xx series have up to 4GSample on board memory.

In FIFO mode it is possible to simultaneously send the data to PC memory and read new data. This is possible with a maximum data transfer rate of 1.7GB/sec. Data reduction is also possible with the option averager and peak detect.

All Spectrum digitizers also have acquisition modes such as Multiple recording (segmented memory), Gated sampling and ABA mode (sample rate switching) for data reduction.

All digitizers come with an extensive package of software support.
Drivers for Windows and Linux operating systems (32-bit and 64-bit) are included.
Example programs and drivers for C/C++, LabVIEW (Windows), MATLAB (Windows and Linux), LabWindows/CVI, IVI, .NET, Delphi, Visual Basic and Python are available.
And a basic license of the Spectrum software SBench 6. Optionally the SBench6-Pro software and the multi card software are available.

For a higher sample rate, please refer to the M4x.22xx digitizers.

These digitizers are also available in a PCI-express format are the M4i.441x, the M4i.442x and the M4i 445x cards.
