Format Gn
The Format command, Gn, 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 (Hn), User Reading Delimiter (In), End of Reading
EOI (Jn), End of Waveform EOI (Kn), Waveform Terminator (Yn), and User
Waveform Terminator (Zn) 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 G0 or G1), data returned from the
Analyzer488 is formatted by using the Hn, In, Jn, Kn, Yn and Zn commands.
If binary format is selected (Format G2 or G3), the Hn, In, Jn, Yn, and Zn
commands will have no effect on the data sent by the Analyzer488. The Kn command
is used with binary data to change the EOI on the End of Waveform selection.
If ASCII format (Format G0 or G1) and waveform 21 (the user waveform) are
selected, the Hn, In, Jn, Yn, and Zn commands will have no effect on the data sent by
the Analyzer488. The Kn command may be used to change the EOI on the End of
Waveform selection.
SYNTAX: G0 ASCII Text with leading '+' sign (default)
