Format Gn

The Format command,

, determines the form of the waveform data returned to

the IEEE controller. Four data formats are available. Depending on the Format

selection, the Reading Delimiter (

), User Reading Delimiter (

), End of Reading

EOI (

), End of Waveform EOI (

), Waveform Terminator (

), and User

Waveform Terminator (

) commands may be used to change the terminator and EOI

selections. A reading is defined as one data point in a waveform. Each waveform

consists of 256 readings.

If ASCII format is selected (Format

), data returned from the

Analyzer488 is formatted by using the

and

commands.

If binary format is selected (Format

), the

, and

commands will have no effect on the data sent by the Analyzer488. The

command

is used with binary data to change the EOI on the End of Waveform selection.

If ASCII format (Format

) and waveform 21 (the user waveform) are

selected, the

, and

commands will have no effect on the data sent by

the Analyzer488. The

command may be used to change the EOI on the End of

Waveform selection.
