A310 Accupulser™ Optional footswitch #3259 STIMULATORS, ISOLATORS Combining the accuracy of digital electronics with the convenience of analog controls A310 ACCUPULSER™ SPECIFICATIONS TIMING PARAMETERS EVENT INTERVAL EVENT DELAY PULSE WIDTH TRAIN DURATION (ENVELOPE) PULSE INTERVAL OUTPUTS SYNC MONITOR ISOLATOR VARIABLE (Pos or Neg) PULSED/DC Range Resolution 5 µs, TTL, and 5 V CMOS compatible, 20 mA max. 10-15 V, 50 mA max. TTL & 5 V CMOS compatible, 20mA max. LOW RANGE 0 to ±1 V 1 mV HIGH RANGE 0 to ±10 V 10 mV 100 µs to1000 s* 10 µs to 100 s * 10 µs to 100 s * 100 µs to 1000 s* 20 µs to 100 s* 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 tenturn readable potentiometers and six-position range switches. Outputs are accurate to within 1% of the set value. 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 the Duo 773 for iontophoresis. Footswitch allows hands-free operation. 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.
