opLabBox 2.0 Ultrasonic Pulser & Receiver
opLabBox 2.0 is a broadband ultrasonic pulser and receiver developed by PBP OPTEL for laboratory measurements, industrial ultrasonic applications and custom test systems. It combines a low-noise wideband receiver, separately switchable high-pass and low-pass filters, programmable gain, an integrated high-voltage step pulser and a graphical user interface in one compact instrument.
It can operate as a self-contained scope adapter or as an analogue front-end / expansion unit for other signal-processing equipment. Together with OPTEL opCard or opBox electronics, it can be used to build a complete ultrasonic measurement system with hardware and software support.

Available on special order
In addition to opLabBox 2.0, OPTEL can supply selected legacy or application-specific pulser/receiver solutions on special order. Availability and configuration should be confirmed for each project.
Frequently asked questions
What frequency range does opLabBox 2.0 cover?
The documented analogue receiver bandwidth is 40 kHz to 25 MHz (−3 dB), with separately switchable high-pass and low-pass filters.
What pulser voltage does opLabBox 2.0 provide?
The integrated step pulser is continuously adjustable from 0 to 360 V, with a documented falling-edge time below 40 ns.
How much gain is available?
The documented total analogue gain range is 104 dB. The regulated range is −10 to +70 dB in 0.1 dB steps, with an additional switchable +0 or +24 dB post-amplifier.
Can opLabBox 2.0 be remotely controlled?
Yes. Remote control uses USB as a virtual RS-232 COM port with an ASCII protocol, allowing integration into automatic measurement setups.
Can opLabBox 2.0 work with one or two ultrasonic transducers?
Yes. The device is intended for classic ultrasonic applications with one or two transducers, including pulse-echo and through-transmission arrangements.
Are other OPTEL pulsers and receivers still available?
Selected OPGUD and OPNEM pulser/receiver products can be supplied on special order. Their exact configuration and availability should be confirmed with OPTEL.
Custom ultrasonic development
Need opLabBox adapted to a specific measurement task?
OPTEL can evaluate the transducer, frequency range, pulser voltage, gain, filtering, automation and software requirements and prepare a customer-specific hardware or system configuration.
