Ri3156b_load_sequence _table
Description
This loads the sequence table using the fast binary download method. Use this function only after you have
loaded the 3156B memory with all of your waveform segments. This function call does not load waveforms to
the memory; It is used to build the sequence table only in one function call. With this function, the programmer
merely states the number of links and their respective segment number and loop count.. This function is an
alternative to calling the ri3156B_define_sequence_step() for multiple times:

ViInt16_segment[], ViInt32_repetitions[])
Parameters
Name
Variable
Type
Description
instrHandle ViSession The Instrument Handle is used to identify the unique
session or communication channel between the driver
and the instrument. If more than one instrument of the
model type is used, this will be used to differentiate
between them. Note that the initialize function may be
used to associate multiple instrument handles with a
single instrument.
numberofSteps
ViInt16
Defines how many steps (links) will be programmed in the
sequence table
Valid range: 1 to 4096
segment
ViInt16[]
Loads an array of numbers which define the segments
that will be used for the sequence table.
Valid range: 1 to 16k
repetition
ViInt32[]
Loads an array of numbers which define the respective
number of repetitions (loops) for each segment that is
placed in the sequence table.
Valid range: 1 to 1M
Return Values
Displays the return status of the function call. If the function was successful, it will return a status of
VI_SUCCESS, otherwise it will return an error code. Passing the error code into the function
"ri3156B_error_message()" will return a string describing the error.
