The dwell time is established from the front
panel control during entry of the waveform.
The display waveforms are executed once
for a specific number of cycles (up to 255) or
indefinitely until stopped. The display allows
for the storage of up to 8 waveforms allowing
a total count of 9 (8 saved, one in RAM).
The interface processor also has a memory.
A total of 1002 steps per program-list are
supported. Each step can have a dwell time
between 250 microseconds to 10 seconds.
The list can be executed from beginning to
end or from end to beginning. It also allows
the list to be executed using a 512-step
sequence. The lists can be executed either
once or through an infinite count.
The RAM list is used for the execution of a
waveform. The RAM list can be saved or
recalled from memory with 16 different
memory lists supported. The 16 different
lists share a 1.5 Kilo-step memory space.
The interface and analog processors provide
the allocation support for these lists as
required. The user memory space can also
be accessed from the interface ports and a
check sum for each list can be calculated and
tested to provide an indication when the
front panel user interface has been used to
modify any user program.
