SYS-A310 Accupulser Signal Generator
- The accuracy of digital electronics with the convenience of analog controls
Features
A pulse generator/stimulator combining the reproducibility and accuracy of digital electronics with the fine resolution and continuous adjustment possible with analog circuitry. All timing parameters are entered with ten-turn readable potentiometers and six-position range switches. Outputs are accurate to within 1% of the set value.
Pulses
Pulses can be created in continuous run, single-shot, or train/burst modes. Duration of the train/burst is easily controlled using the onboard envelope generator or by using either of two external gating inputs. Used in conjunction with the A360, A365, A385, or A395, bipolar pulses or trains may be easily produced. Output stimulus can be fed through Intra 767 or Duo 773 for iontophoresis. Footswitch allows hands-free operation.
Three separate outputs
Three separate outputs are available on the front panel. A Monitor output provides 10-15 V signals (up to 50 mA) for viewing the output on an oscilloscope or for controlling other devices. The stimulator’s signal, simultaneously available at the Isolator output, is sufficient to drive any WPI A300 Series stimulus isolator (A360, A365, or A385) and is also TTL and CMOS compatible. The Variable output can provide signals varying between ±10 V with a resolution of 1 mV. Separate variable outputs are provided for positive and negative signals.
