Data Transmission Formats

You have the option to select which data transmission format you want to use. By default all data is transfered in ASCII format. Some commands support binary data transmission (eihter 64-bit or 32-bit format). The data transfer format can be set with :FORMat[:DATA].

The commands that support NON-ASCII data transmission are the following:

• :CALCulate:DATA:SDATa
• :SENSe:FREQuency:DATA

ASCII Transmission

The ASCII Data Transmission format can be selected by calling (:FORM:DATA ASC), but is selected by default. The figure below shows the ASCII format of decimal values. The number of decimals is 6 and the number of digits of the exponent are 3 by default.

Binary Transmission - 32 Bit

The Binary Data Transmission format (64 bit) can be selected by calling (:FORM:DATA REAL32). The figure below shows the composition of the Binary Data transfer format (32 bit). It consists of a header and data part. The data is split into sign, exponent and fraction (IEEE standard).

Binary Transmission - 64 Bit

The Binary Data Transmission format (64 bit) can be selected by calling (:FORM:DATA REAL). The figure below shows the composition of the Binary Data transfer format (64 bit). It consists of a header and data part. The data is split into sign, exponent and fraction (IEEE standard).
