Theory Of Operation - A.M.P.I. Master-8 Operation Manual

3. Theory of Operation

Each channel uses its own clock, and can thus run independently of the other
channels. You can also connect the channels internally to each other (no
connection wires between the channels are needed), in all possible combinations
in order to form simple or complex protocols.
Each channel operates in any of the following modes:
● FREE-RUN - the channel delivers pulses continuously
TRIGGER - following a trigger, the channel delivers a single pulse
●
● TRAIN - following a trigger, the channel delivers a train of pulses
● DC - the channel is time independent, it can be turned on and off manually
● GATE (channels 1 and 2 only) - the channel delivers pulses continuously
while it is externally gated
Channels 1 and 2 can receive external triggers. This enables synchronizing
channels with external devices.
Master-8 features a clock which measures the time that has elapsed after
pressing the CLOCK-RESET key (e.g. the experiment time). It also features a
timer which can change the operational mode of a channel at a certain hour
(e.g. turn the channel on or off).
You can adjust the amplitude of the output pulses from -10V to +10V, with a
maximum current of 20mA.
