opBox is OPTEL’s compact ultrasonic acquisition family for NDT, research and industrial measurement systems. The product line is organized by function rather than as a simple replacement sequence.
opBox 2.1 is the standard single-channel version, opBox 2.2 is the dual-channel version with two transmitters, and opBox 2.3 OEM is designed for integration into custom equipment.
opBox 2.1 is the standard version of the opBox family. It provides one ultrasonic measurement channel with an integrated high-voltage pulser, low-noise receiver and digital acquisition in a compact USB-connected instrument.
| Channels | 1 standard ultrasonic measurement channel |
|---|---|
| Receiver gain | Adjustable −31 to +65 dB in 0.5 dB steps, with switchable +24 dB preamplifier |
| Input attenuator | Switchable −20 dB |
| Receiver bandwidth | 0.5–25 MHz (−3 dB) |
| Analogue filters | 16 switchable HPF/LPF combinations |
| Pulser | 0–360 V positive pulse; adjustable loading time 0–3.1 µs |
| ADC | 10 bit; 8-bit samples stored in the documented implementation |
| Sampling frequency | Up to 100 MHz |
| Acquisition buffer | Up to 262,090 samples (approx. 256k) |
| Interface | USB 2.0 High Speed |
| Power | USB bus powered, below 500 mA |
| Real-time acquisition | Architecture designed for up to 10,000 measurements/s, depending on acquisition window and USB data load |
opBox 2.2 is the two-channel member of the family. It is intended for measurements that require two ultrasonic channels and two transmitters, while retaining the compact USB instrument concept.
| Channels | 2 ultrasonic channels |
|---|---|
| Transmitters | 2 integrated ultrasonic transmitters |
| Receiver noise | 0.74 nV/√Hz preamplifier specification |
| Receiver gain | Up to approximately +89 dB with receiver stages |
| Input attenuator | Switchable −20 dB |
| Analogue filtering | Switchable high-pass and low-pass filters |
| Pulser | Two-channel high-voltage pulser, up to 460 V |
| ADC | 10 bit; acquired data stored as 8-bit samples in the documented implementation |
| Sampling frequency | Up to 100 MHz |
| Interface | USB 2.0 |
| Power | USB powered |
opBox 2.3 OEM is the OEM-oriented member of the opBox family. Its role is system integration: embedding OPTEL ultrasonic acquisition electronics into customer machines, automated NDT stations and dedicated measurement equipment.
| Product type | OEM ultrasonic data-acquisition module |
|---|---|
| Sampling frequency | Up to 100 MHz |
| Pulser voltage | Up to 460 V |
| PC interface | USB 2.0 |
| Power supply | 5 V via USB 2.0 |
| Documented hardware revision | 2.3.90 |
| Intended use | Embedded / OEM ultrasonic measurement and NDT systems |
opBox 2.3 OEM is presented here as the OEM integration version, not as a replacement for the standard opBox 2.1 or the dual-channel opBox 2.2.
Use opBox 2.3 OEM when the ultrasonic electronics are to become part of a larger custom machine or OEM product.
opBox 2.1 is the standard single-channel version of the OPTEL opBox ultrasonic acquisition family. It combines one ultrasonic measurement channel with an integrated pulser, receiver, 10-bit ADC, programmable gain and filtering, and USB 2.0 communication.
opBox 2.1 is the standard single-channel version. opBox 2.2 is the dual-channel version with two ultrasonic transmitters, intended for applications that require two active ultrasonic channels.
opBox 2.3 OEM is the version intended for integration into custom machines and OEM ultrasonic systems. It is an integration platform rather than a replacement for the standard opBox 2.1 or dual-channel opBox 2.2.
Yes. opBox devices can be integrated with transducers, multiplexers, scanners, automation and custom software as part of laboratory, industrial and OEM ultrasonic measurement systems.
Yes. OPTEL also provides an opBox 2.1 variant developed for CMUT transducers; suitability depends on the specific CMUT biasing and interface requirements.
OPTEL can evaluate the measurement physics, transducer arrangement, electronics, channel routing and software before a full system is built.
