ALGorithm
Comments
Specifying a value of 1 (the default) causes the named algorithm to be executed each
time a trigger is received. Specifying a value of n will cause the algorithm to be
executed once every n triggers. All enabled algorithms execute on the first trigger
after INIT.
time a trigger is received. Specifying a value of n will cause the algorithm to be
executed once every n triggers. All enabled algorithms execute on the first trigger
after INIT.
•
The algorithm specified by <alg_name> may or may not be currently defined.
The specified setting will be used when the algorithm is defined.
•
Related Commands: ALG:UPDATE, ALG:SCAN:RATIO?
•
When Accepted: Both before and after INIT. Also accepted before and after
the algorithm referenced is defined.
•
*RST Condition: ALG:SCAN:RATIO = 1 for all algorithms
•
Send with VXIplug&play Function: hpe1422_cmd(...)
Usage
ALG:SCAN:RATIO 'ALG4',16
ALG4 executes once every 16 triggers.
ALGorithm[:EXPLicit]:SCAN:RATio?
ALGorithm[:EXPLicit]:SCAN:RATio? ’<alg_name>’
returns the number of
triggers that must occur for each execution of <alg_name>.
Comments
•
Since ALG:SCAN:RATIO is valid for an undefined algorithm,
ALG:SCAN:RATIO? will return the current ratio setting for <alg_name> even
if it is not currently defined.
if it is not currently defined.
•
Returned Value: numeric, 1 to 32,768. The type is int16.
•
Send with VXIplug&play Function: hpe1422_cmdInt16_Q(...)
ALGorithm[:EXPLicit]:SIZE?
ALGorithm[:EXPLicit]:SIZE? ’<alg_name>’
returns the number of words of
memory allocated for algorithm <alg_name>.
Parameters
Comments
•
Since the returned value is the memory allocated to the algorithm, it will only
equal the actual size of the algorithm if it was defined by ALG:DEF without its
[<swap_size>] parameter. If enabled for swapping (if <swap_size> included at
original definition), the returned value will be equal to (<swap_size>)*2.
[<swap_size>] parameter. If enabled for swapping (if <swap_size> included at
