Output sequencer

The sequencer controls up to 8 waveform and 16 digital outputs from a CED 1401 interface. A graphical editor gives a user-friendly display of the selected outputs for fast and easy creation of stimulus protocols. There is also a text editor which gives direct access to the sequencer instruction code for more complex output and control requirements.

• Drag-and-drop pulses from a palette onto output tracks in the editor
• Modify pulse timing and amplitudes quickly and easily
• Use digital pulses and pulse trains to trigger external devices
• Generate variable amplitude square pulses, sine waves and voltage ramps to control external equipment
• Combine pulses such as square waves and ramps for ramp-and-hold
• Control variable intensity stimuli such as temperature, current and voltage
• Output user-defined waveforms, pre-recorded and imported data for control and stimulation
• Define pulse protocols as separate sections in the output sequencer and link them together for automated stimulus sequencing
• Copy pulse information between sections to quickly set up a series of similar stimulus protocols
• Make use of control statements such as loops and branches and randomise delays and stimuli
• Record digital input states directly to a marker channel and generate codes to flag events
• Read digital input and sampled waveform values directly and branch on the result if a given condition is met
