DG-535 Interactive Pulse Width and Delay dialog box
The Interactive Pulse Width and Delay dialog box, accessed with the button of the
Custom toolbar, allows you to control the Pulse Width and Pulse Delay parameters of a
DG-535 or PTG timing generator while acquiring data.
Parameters
Pulse Width:
The pulse width is the duration of the pulse applied to the PI-MAX
intensifier to gate the photocathode. The units available are nanoseconds (nsec),
microseconds (µsec), or milliseconds (msec). Because only certain specific
values are allowed, the timing generator adjusts the input value to the nearest
allowable value.
Pulse Delay:
The pulse delay is the time between the beginning of the trigger pulse
(either internal or external) and the beginning of the photocathode gate pulse.
The units available are nanoseconds (nsec), microseconds (µsec), or milliseconds
(msec). Because certain specific values only are allowed the timing generator
adjusts the input value to the nearest allowable value.
