Digitimer DG2A - Train/Delay Generator

This small free-standing instrument has been designed for control of normal repetitive stimulation as well as for defining the Effective Refractory Period using a second, delayed pulse. This unit is especially useful as a frequency generator (as a TTL trigger source) for use with our DS2A, DS3 and DS7A isolated stimulators which have their own pulse duration controls. The basic features of it's predecessor the DG2 Trigger Generator have been extended to allow trains of pulses to be generated in response to input signals from other devices.
