OPCARD 3.0 – Ultrasonic Acquisition CardThe OPCARD 3.0 ultrasonic acquisition card is designed to operate as a core component of ultrasonic testing systems compliant with the requirements of the ISO / PN-EN 12668 series for ultrasonic non-destructive testing equipment.
The device enables system-level compliance when integrated with appropriate probes, calibration blocks, and software.


Applicable Standards

• PN-EN ISO 12668-1
• Non-destructive testing — Characterization and verification of ultrasonic examination equipment — Part 1: Instruments
• PN-EN ISO 12668-2
• Non-destructive testing — Characterization and verification of ultrasonic examination equipment — Part 2: Probes
• PN-EN ISO 12668-3
• Non-destructive testing — Characterization and verification of ultrasonic examination equipment — Part 3: Combined equipment

Compliance StatementOPCARD 3.0 fulfills the functional and performance requirements specified in ISO / PN-EN 12668-1 for ultrasonic instruments, including:

• Stable and repeatable pulser output parameters
• Low-noise receiver characteristics
• Programmable gain and linearity
• Wide and configurable analog bandwidth
• Accurate and repeatable A/D conversion
• Reliable timing, triggering, and synchronization

When used in combination with qualified ultrasonic probes compliant with ISO / PN-EN 12668-2, the complete ultrasonic system incorporating OPCARD 3.0 may be verified in accordance with ISO / PN-EN 12668-3.


Relevant Technical Parameters Supporting Compliance

• Integrated high-voltage pulser up to 460 V, suitable for standardized probe excitation
• Ultra-low-noise receiver front end (< 1 nV/√Hz)
• Programmable gain range with fine resolution (0.5 dB steps)
• Configurable analog filtering (high-pass and low-pass)
• Wide operational bandwidth: 0.5–25 MHz (–3 dB)
• Precision 12-bit ADC, sampling rate up to 100 MHz
• High PRF capability up to 100 kHz
• Stable timing and triggering for repeatable measurements
• On-board memory enabling consistent acquisition conditions

Verification and CalibrationVerification of systems based on OPCARD 3.0 can be performed using standard calibration procedures and reference blocks as defined in ISO / PN-EN 12668, including:

• Sensitivity and gain linearity checks
• Time base accuracy verification
• Noise level and dynamic range evaluation
• Bandwidth and frequency response characterization

Calibration and verification results depend on the complete system configuration, including probes, cabling, and software environment.


NoteOPCARD 3.0 is a modular ultrasonic acquisition platform intended for integration into customized ultrasonic systems. Final conformity with ISO / PN-EN 12668 requirements applies to the complete ultrasonic examination system, not to the acquisition card as a standalone component.
