|---|---|
| Onboard memory | 8 GB DDR4 |
| Trigger modes | Hardware, software and manual triggering |
| Acquisition mode | Continuous sampling supported |
Software and integration
The MSDK software development kit supports Windows and Linux, with integration support for C/C++, MATLAB, LabVIEW, Python, C# and Qt. The supplied software includes interface libraries, demonstration examples and development documentation. Host demo software provides board configuration, real-time data display and storage.
Applications and selection guidance
Typical applications include waveform recording, multi-channel transient recording, mass spectrometry, particle physics and life-science instrumentation. Select the analog input bandwidth and sampling rate for the signal being measured, then review the output bandwidth and playback rate separately for the waveform to be generated.
Before integration, confirm the required input range and coupling, trigger arrangement, acquisition/playback timing and sustained transfer requirements with the host PC. Onboard memory capacity does not establish continuous host-to-disk recording performance.
