A310 Accupulser™ Pulse Generator

World Precision instruments

INTRODUCTION

the model A30 Accupulser™ is a second generation pulse generator/stimulator 
that combines the reproducibility and accuracy of digital electronics with the fine 
resolution and continuous adjustment characteristics of analog circuitry. All of the 
A30's timing parameters are entered via ten-turn readable controls and six-position 
range switches. combining the accuracy of ten-turn dials with the A30's highly 
linear circuitry allows the outputs to be accurate to within % of the set value, over a 
range of seven orders of magnitude.

the A30 can produce single or double pulses in either continuous run, single-shot 
or train/burst modes. the duration of the train/burst is easily controlled by using the 
onboard envelope generator or by externally provided potential or dry-contact gating 
inputs.

Five separate outputs are available from the A30. the isolAtor output is designed 
to drive a WPi stimulus isolator and is also compatible with ttl and 5-volt cmos 
circuits. the monitor output provides 0-5 volt (up to 50 milliampere) signals for 
viewing the output on an oscilloscope/recorder or for controlling other devices. A pair 
of low noise, VAriABle outputs are amplitude variable from zero to +0 volts and 
-0 volts, in two ranges, with a resolution of one millivolt. the ttl and 5 volt cmos 
compatible, sYnc output provides short duration pulses which are synchronized with 
the beginning of each output interval. 

Panel lights indicate when the user set parameters result in logical timing violations 
and when the outputs are active.
