returns the value of
the scalar variable <var_name> in algorithm <alg_name>.
Parameters
Comments
•
An error is generated if <alg_name> or <var_name> is not defined.
•
Returned Value: numeric value. The type is float32.

ALGorithm[:EXPLicit]:SCAN:RATio
ALGorithm[:EXPLicit]:SCAN:RATio ’<alg_name>’,<num_trigs>
specifies the
number of scan triggers that must occur for each execution of algorithm <alg_name>.
This allows the specified algorithm to be executed less often than other algorithms.
This can be useful for algorithm tuning.

Notes
1. The command ALG:SCAN:RATio <alg_name>,<num_trigs> does not take
effect until an ALG:UPDATE or ALG:UPD:CHAN command is received.
This allows multiple ALG:SCAN:RATIO commands to be sent with their
effect synchronized with an ALG:UPDATE command.
This allows multiple ALG:SCAN:RATIO commands to be sent with their
effect synchronized with an ALG:UPDATE command.
2. ALG:SCAN:RATio places a variable update request in the Update Queue.
More update requests cannot be placed in the Update Queue than are allowed
by the current setting of ALG:UPD:WINDOW or a "Too many updates ––
send ALG:UPDATE command" error message will be generated.
