    The DS8000 represents a quantum leap in the performance of the research stimulator. Using a powerful single board computer, DS8000 is the most advanced stimulator on the market. With a built-in computer, all of the waveform is generated digitally with precision timing. It can generate more complex stimulating wave patterns than any other instrument on the market. The LCD touch screen display/input makes a vast improvement and ease of operation for the user interface. A built in digital oscilloscope will allow the user to check the waveform instantly on the screen. The instrument can be rack mounted with all of the frequently used connectors on the front panel. An Ethernet connection allows the user to transfer custom waveforms and upgrade the software using TCP/IP protocol via remote Ethernet access.

    The DS8000 has 8 analog outputs, 8 TTL outputs and 8 combined analog or TTL outputs. Each combined output can be comprised of a combination of any 1 to 8 channels. Three independent internal timers and three independent external triggers are offered. The output waveforms include unipolar pulse, bipolar pulse, rectangular pulse, step, sine and ramp. In addition, researchers can design their own waveforms. An external trigger, internal analog channel, internal TTL channel, or any of the three built-in timers can be used to control each output channel. All of the three built-in timers can be programmed and linked to perform complicated timing schemes.

    A unique feature of the DS8000 is stimulation with a waveform that is identical or similar to a real biopotential waveform, such as ECG, EEG, EPSP/IPSP or action potential, providing the scientist with much more information than would a simple square waveform. A biopotential waveform captured by a data acquisition system may be transferred to an Excel spreadsheet for editing or modification, and then sent to the DS8000.

    One of the main problems of designing a stimulator is that a user might want very different stimulating patterns for different research applications. In order to satisfy all of these needs, traditional logical circuit based stimulators have control panels that use buttons and knobs to give the user as much control options as possible. However, even with a full panel of buttons, the selection of the stimulating pattern is still very limited. These types of stimulators can not generate complicated waveforms, such as combination pulses at varying interpulse intervals and amplitudes. Although microprocessor-based stimulators have made a significant step in solving these problems, some complicated waveforms are still impossible to generate. In fact, this decade old technology has serious limitations since each control button has been programmed to perform multiple functions. Moreover, it can only display limited lines of scrolled text -no graphics! To complicate matters, it is almost impossible to upgrade the software with new functions once the instrument has been manufactured; even the programming is awkward.

    The DS8000 overcomes the hardware limitations of other types of stimulators by being reliant on a flexible software-timing interface. The user can then apply this flexibly to almost any kind of stimulation protocol without being restricted by the hardware limitations of the traditional logical circuit based stimulators. In order to suit complex custom protocols, the DS8000 is designed to offer a unique flexibility by simply reprogramming the pattern output using a few keystrokes under pull-down menus.

    Although personal computer (PC)-based stimulators have the potential to give the user many of these options, they have major limitations that are inherent to the nature of PCs. Fundamentally, the timing on PCs is not accurate because computers have higher priorities to do other operations first. As a result of these other priorities, the important timing required for research stimulation becomes unstable. Despite the fact that PCs are very economical, they are not specifically designed to give accurate timing outputs. Furthermore, analog waveform generation is not readily available without adding expensive output boards and the required programming is non-standard. Besides, it is very inconvenient to make connections from the back of a PC using parallel ribbon cables. On the other hand, a dedicated single board computer controller, as used in the DS8000, allows very complicated waveforms to be easily generated with very accurate and precise timing. Yes, WPI’s Digital Stimulator offers all of these solutions plus Good Laboratory Practices (GLP) compliance for research traceability.

DLS100 digital linear stimulus isolator 

  • Specially designed for use with the DS8000 digital stimulator 
  • High isolation and fast signal rise and fall times
  • Two modes: current source and voltage source
  • Designed for Physiology applications

  

Optical Coupling

    DLS100 connects to the DS8000 via a flexible cable through which it receives power and stimulus signals in a digital format. Up to eight DLS100 isolators can be connected independently to one DS8000. Very high isolation is achieved through the use of optical coupling of the digital signal and a galvanically isolated DC power supply within the DLS100. Unlike some other multi-channel isolators, this digital isolator can be located at the site of the experiment, allowing the use of short connecting leads and thereby preserving high isolation and fast signal rise and fall times.

Two modes

    The DLS100 operates in two modes: current source or voltage source. In the current source mode, the output current is proportional to the amplitude and polarity of the signal generated by the DS8000. In the voltage source mode, the output voltage is proportional to the amplitude and polarity of the signal generated by the DS8000. The DLS100 has user-selectable push-button switches that select different current or voltage ranges (the full-scale current from 100 nA to 10 mA, or the 10V and 100V full-scale, respectively). Three status indicators on the DLS100 indicate power on, activity (presence of signal from DS8000) as well as an alarm (over-range condition) indicator. Over-range can occur when the resistance of the load (the experiment) is too high for the current or voltage that is demanded from the DLS100.
