The accuracy of digital electronics and the convenience of analog controls

  • Single channel pulse generator with train capability
  • TTL and variable voltage output



  • Variety of pulses: continuous run, single-shot, train/burst
  • Multiple outputs available: monitor, isolator, sync and variable


  • Electrophysiology

The A310 pulse generator/stimulator combines the reproducibility and accuracy of digital electronics with the fine resolution and continuous adjustment pos­si­ble with analog circuitry. All timing pa­ram­e­ters are entered with high resolution, ten-turn po­ten­ti­om­e­ters and six-position range switches. Timing is ac­cu­rate to within 1% of the set value.

Variety of Pulses

Pulses can be created in continuous run, single-shot or train/burst modes. Duration of the train/burst is 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, constant current pulses and trains can be created easily. A foot switch allows hands-free, manual triggering.

Multiple Outputs Available

Five separate standard BNC outputs are available on the front panel. The isolator output sends full pulse width control signals to any TTL triggered stimulus isolator, such as WPI’s A360, A365 or A385 and others. The monitor output sends synchronized large scale full pulse width signals to recording or monitoring instrumentation such as a data acquisition system or oscilloscope. The sync output provides an additional synchronized 5 µs TTL pulse for triggering external instrumentation. A variable voltage output provides two separate full pulse width signals in both positive and negative polarities in two ranges for applications that require a specific output voltage other than TTL.

Three separate outputs

Three separate outputs are available on the front panel.

  • Monitor output provides 10-15 V signals (up to 50 mA) for viewing the output on an oscilloscope or for controlling other devices.
  • Pulse stimulator’s signal, simultaneously available at the Isolator output, is sufficient to drive any WPI A300 Series stimulus isolator (A365 or A385) and is also TTL and CMOS compatible.
  • 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.
