Master-8 is an 8 channel pulse generator. With Master-8 you can easily switch your set-up between completely different experiments (paradigms). Master-8 stores eight user’s preprogrammed paradigms. Each paradigm can use all the eight channels. You can switch your set-up to the selected setting by a single command. This option is very useful in the following cases: a) When you want to switch the experiment to another one. The changeover is very fast (50 msec). b) When several users are using the same set-up. Each user recalls his settings from the memory of Master-8. All parameters of all the 8 paradigms are stored in the memory even after the power is switched off by a lithium battery with a guaranteed life of 7 years. There is no need to reinsert the parameters after switching on the unit.
