OPERATING DIRECTIONS

the model A30 Accupulser™ is designed to make the operation of the instrument 
as self-explanatory as possible. extensive graphics are provided on the front panel to 
guide the user with the function of each of the controls and connectors. Before using 
the following instructions, it is recommended that the user should read about each 
panel component in the controls, indicators and connectors section of this manual. 
the following operating directions are provided as typical instrument setups, that 
would result in valid operating modes.

Pulse

in the pulse mode, the instrument provides single or double pulses of user set widths. 
the train generator is disabled by the user. in the single pulse mode, the pulse is 
delayed after the start of the event interval. in the double pulse mode, a second pulse 
is provided, starting at the same time as the event interval.

in the continuous on input mode, the time parameters for the event interval, 
the event delay and the pulse width are set on the panel controls by the user. in the 
eXt sYnc input mode, the internal clock is disabled and the event interval starts 
whenever an input sync pulse is applied. in the sinGle eVent mode, one event 
interval occurs for each push on the switch. in the eXt GAtes input mode, the panel 
set event interval time is active as long as either of the gate signals is active. the eXt 
GAtes feature allows the generation of a train of train pulses. At the outPut sYnc 
connector, a narrow pulse is provided every time an event interval starts.

the output signal from the instrument is available at four different connectors. the 
time parameters at each of the connectors are identical. the differences among the 
outputs are due to the amplitude of the signal and the source/sink current capability 
of each circuit. these differences are described in the specification section of this 
manual.

it is possible to set the panel controls so that conflicting timing parameters are 
provided. in order to assist the user, the ViolAtion light is illuminated for one 
second, whenever one time interval improperly overlaps another. As a further aid, the 
outPut light is illuminated for the duration of every output pulse and train duration.
