Bytes 12 thru 15 contain 4 user selectable characters for the file name 

Byte 16 contains Sampling rate information and shall be decoded in accordance with the table below: 

Table 3: Sampling rate code 

 

Bytes 17 and 18 contain Trigger level settings where byte 17 includes the whole part and byte 18 has 
the decimal part of the level designation 

Byte 19 has the triggering axis information
