Human Physiology and Research
Digitimer has a long history of designing and manufacturing high output electronic stimulators and amplifiers that are completely safe for use by researchers and clinicians for a variety of applications. Many have also been designed and FDA certified for use on patients undergoing surgery. Digitimer amplifiers are low mains noise solutions for accurate recordings of signals such as EMG/EEG.
High output, low mains noise, and human safety are Digitimer hallmarks.

SPP-400 Trigger Generator
-
Intuitive Touchscreen Interface: Say goodbye to knobs and buttons. The SPP-400 features a responsive touchscreen that allows for fast, precise control over all your settings. You can program complex sequences with just a few taps, making your workflow more efficient.
-
Precision Pulse Generation: With an incredibly high degree of accuracy, the SPP-400 generates pulses and delays with the reliability essential for your experiments.
-
Dual Output Ports: The device includes two independent output ports, giving you the flexibility to control multiple devices or trigger separate events simultaneously.
-
Modern Connectivity: The SPP-400 is equipped with a USB-C port for both power and data, ensuring seamless integration with your existing setup and future devices.
-
Programmable digitally-controlled, single or two channel trigger source compatible with our range of electrical stimulators. Cable of operating in multiple modes, including (i) Free Run (ii) Gated (iii) Single or (iv) Train. However, because the SPP-400 can be used as a single or two channel device, with the output of Channel 1 linked to the input of Channel 2, it can also produce repeating trains or bursts of pulses which would be impossible with a single DG2A.
