DSPAUT SDK (DSK)
C# Ultrasonic Library

DSPAUT SDK (DSK) is a dedicated C# development library designed to control the measurement engine of DSPAUT phased array ultrasonic testing (PAUT) hardware (P5, B3, R5, etc.) programmatically. Acquire, process, and map real-time ultrasonic signals to custom visual layouts using the `SVDSK.dll` assembly.

LIBRARY STRUCTURE

Intuitive C# SDK Referencing & Clean Architecture

Enables developers to quickly prototype and deploy customized NDT software in Windows 10 using Visual Studio 2017 and above. Simply add the core C# assembly `SVDSK.dll` and the helper library `DskCommon` to your project references. The execution operates directly from the build output directory (`../Bin/Release_x86`), and resources are cleanly decoupled and managed within `CommonResource`.

  • ✔ Provides clean C# .NET 8.0 classes and properties for all device parameters
  • ✔ Direct hardware access via the `DSPAUT` namespace API calls
  • ✔ Unified debugging and diagnostic trace logging using Log2console integration
PHYSICAL LEVEL CONTROLS

Low-Level Parameter Adjustment & Gate Control

Fine-tune pulser-receiver settings programmatically via C# functions to optimize signal response. Manage gain, digitizing frequency indexes, PRF, and voltage levels (ranging from 25V to 200V). Leverages bipolar pulsing to customize Burst Counts (from 1 to 5 cycles), boosting acoustic penetration in highly attenuative industrial materials.

  • ✔ Real-time position, range, and threshold management of 3 independent gates (Gate A/B/I)
  • ✔ Configure transmitter/receiver element limits and hardware frequency bandpass filters
  • ✔ Channel Group configuration organizes multi-vector arrays to stream through Rx callbacks

01-InitDevice application run TUTORIAL 01

01-InitDevice

Device Connection & Real-time Acquisition

Initializes the hardware using `InitDsk` and `InitDevice` commands, starting acquisition channels to capture incoming data. Uses `Dsk.Freeze` and `UnFreeze` properties to control streaming programmatically.

02-SScan application run TUTORIAL 02

02-SScan

Real-time S-Scan Image Conversion

Demonstrates coordinate mapping logic converting raw A-scans to a 2D sectorial scan visual. Gathers boundaries using `GetSScanWidth`/`Height` and computes 2D byte arrays using `CalcSScanImage`.

03-AScan application run TUTORIAL 03

Extracting Beam Waveforms & A-Scans

Retrieves signal amplitude data for a user-specified focal law index. Processes multi-beam signals in real-time, displaying linear waveform graphs directly on a custom bitmap surface.

04-Inspection application run TUTORIAL 04

04-Inspection

Multi-Axis Encoder & Distance Tracking

Essential for mechanical crawlers and automated industrial scanning. Uses `SetScanEncoder` to set bounds, step sizes, and pulse resolution to track physical movement in millimeters.

C# Integration Guide

A few lines of code to control
Ultrasonic Hardware

The official SDK hides lower-level register complexities inside clean, object-oriented C# wrappers. Initialize the device and bind the real-time callback using simple C# constructs.

Step 1

Import the DEEPSOUND Namespace

Add referencing declarations in your C# assembly entry points.

Step 2

Initialize Device Engine

Call `InitDsk()` and `InitDevice()` to gain hardware access.

Step 3

Bind SetCallBackFrame

Register callbacks to receive real-time frame arrays containing locational coordinates.

DskTutorial / Program.cs
C# (.NET 8.0)
// 1. Import DSK Namespace Assembly using System; using DEEPSOUND; namespace DskTutorial { class Program { static void Main(string[] args) { // 2. Initialize DSK engine DSK.InitDsk(); // 3. Boot high-speed Gigabit Ethernet/USB hardware bool isDeviceReady = DSK.InitDevice(); if (!isDeviceReady) { Console.WriteLine("Device connection failed!"); return; } // 4. Link callback function to fetch raw frames DSK.SetCallBackFrame(new DskCallBackFrameX(OnReceiveFrameX)); Console.WriteLine("Streaming active. Press any key to stop."); Console.ReadKey(); // 5. Safely release device handles on exit DSK.CloseDevice(); } // Rx callback capturing real-time frame & coordinate (X-axis) private static void OnReceiveFrameX(short[] frameData, double locX) { // Real-time signal processing routing here Console.WriteLine($"Frame Received - Pos: {locX}mm, size: {frameData.Length} shorts"); } } }
