The Digitimer D440 Isolated Amplifier is a high-performance, low-noise solution specifically developed for human EMG recording and nerve excitability studies. Compact and standalone in design, the D440 combines exceptional signal quality with flexible connectivity and software integration, making it an ideal tool for advanced electrophysiological research.
Engineered to deliver reliable, low-noise signal amplification, the D440 features a wide amplification range (x100 to x20,000), AC and DC recording modes, and selectable filters to optimize recordings across a wide range of experimental needs. Each input channel is independently controlled, allowing researchers to precisely tailor their setup, whether working with two or four recording sites.
Designed to integrate seamlessly into modern research workflows, the D440 supports USB-based software control via its included Virtual Front Panel and COM interface, making it compatible with custom software applications and third-party platforms like QtracW. This makes it especially well-suited for users performing threshold tracking and nerve excitability measurements, particularly in combination with the Digitimer DS5 Constant Current Stimulator.
Standard electrode connectors (1.5mm DIN and 5-pin DIN) ensure compatibility with existing lab setups, while analog BNC outputs provide straightforward connectivity to any data acquisition (DAQ) system. Each unit is supplied with all necessary interface and electrode cables, enabling fast and efficient setup in any research environment.
The D440 also includes a manual and externally triggerable deblock function, helping to minimize stimulation artifacts such as those generated during magnetic stimulation. Channels not in use can be electronically grounded, reducing system noise and ensuring clean, accurate data.
