Description Specifies the system identifier. This is given by the
"hpe5022_init" function.
Direction IN
Description Returns the data (set in array) of the error length. The size of
array is 10. The err[0] to err[8] are the number of error
lengths 1 to 9, respectively. Err[9] represents the number of
error length over 10.
Direction OUT
Description
No Error
Description
The handle specified by 'id' is invalid.
The result is not accurate because there
are too many errors to count.
The bit error measurement data is corrupt.
Check if your measurement sequence is
correct.
The resource of E5039A/B can not be
opened during initialization. Check if
E5039A/B is included in the rsrcArray of
the "hpe5022_init" function.
