Data Types and Encoding

Data Types and Encoding

Data is transferred between the analyzer and a controller via the GPIB
data lines, DIO1 through DIO8. Such transfers occur in a byte-serial (one
byte at a time), bit-parallel (8 bits at a time) manner. This section
discusses the following aspects of data transfer:

• the different data types used during data transfers

• data encoding used during transfers of numeric block data
