NL301 – Pulse Generator
The NL301 is a low cost module for producing trains of uniform TTL pulses. It can be operated continuously, switched off, or a single pulse can be triggered manually. A “gate” input socket is provided to allow synchronous trains of pulses to be gated-on by an externally applied TTL signal. Pulse frequency is continuously variable over more than three decades and three fixed output pulse widths are available.



NL304 – Period Generator
The NL304 contains a crystal oscillator and frequency dividers for producing a precise, stable frequency standard. It can be externally gated (GATE IN) and synchronised with an external source (RESET input). The pulse train can be switched off and a single output pulse can be produced manually by a front panel push switch. The NL304 is the basic “clock” of the NeuroLog System as it provides the “fine grain”….



NL412 – Pulse
The NL412 is a small, handheld, general purpose pulse generator which can be used to “start”experiments, command the “gate” of a train of pulses or be used with an NL102G DC Preamplifier to “Buzz” electrodes. The NL412 is self-powered by a standard internal 9 Vbattery and is fitted with a 2 m lead terminating in the standard Lemo connector. It is now supplied with all new NL102G amplifiers.
