Control measurement device ATLAS™

for medical devicescompactdigital

The ATLAS™ Test System was designed by Acertara for diagnostic ultrasound transducer manufacturing and development; including in-process probe testing, quality control, probe production final test, and engineering. A major design goal of ATLAS ™ was the ability to replicate the results of legacy test systems. ATLAS™ is flexible, expandable, and customizable. Users have the ability to include or exclude operational modules from the final software package such as : re-poling, time-of-flight calculation methods, cross talk, and various other transducer acceptance criteria matrices. ATLAS™ is highly intuitive for both new users or those who have been previously trained to other array test systems. Features • Hardware design electronics elements: - The ultrasound pulser - The ultrasound receiver - The impedance measurement module - The element selection matrix - The data conversion and PC interface • Fundamental software elements: - Test setup - Array Alignment - Pulse Echo Measurement - Impedance Measurement Module - Judgement/Acceptance criteria - Results save and database - Report Generation Specification Frequency Sweep Direct Digital Frequency Synthesis Accuracy/Stability +/-80ppm Range 0.05 – 100MHz Sweep Time 0.1 to 8.0 seconds Source to Hydrophone Distance Continuously variable Input Impedance selectable high impedance or 50 Ohms IF Sampling 16 bit A/D, two megabytes sample storage Operating Environment +10 to +40°C Source Output -20 to +20dBm, +/-0.5dB (0.5MHz to 50MHz) into a 50 Ohm resistive load Sensitivity +/-0.5 Vp-p +/-0.5dB for full scale (0dB) output at 5MHz
