3. Theory of Operation
Each channel operates independently in one 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
You can connect the channels internally to each other, therefore there is no need to connect wires
between the channels.
The Master-8-cp model can be programmed by a computer via a standard RS-232 interface. The
communication is bi-directional.
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 mode of a
channel at a certain hour (i.e. 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.
