Waveform Template

This appendix contains the Waveform Template that describes the contents of the Waveform Descriptor that

is produced by the commands WF? DESC and WF? ALL. After the template are explanations of the

construction of floating point numbers from bytes in the descriptor, followed by program fragments that show

a method of performing the calculations.

; Explanation of the formats of waveforms and their descriptors on the

; LeCroy Digital Oscilloscopes,

; Software Release 8.1.0, 98/09/29.

;

; A descriptor and/or a waveform consists of one or several logical data blocks

; whose formats are explained below.

; Usually, complete waveforms are read: at the minimum they consist of

; the basic descriptor block WAVEDESC

; a data array block.

; Some more complex waveforms, e.g. Extrema data or the results of a Fourier

; transform, may contain several data array blocks.

; When there are more blocks, they are in the following sequence:

; the basic descriptor block WAVEDESC

; the history text descriptor block USERTEXT (may or may not be present)

; the time array block (for RIS and sequence acquisitions only)

; data array block

; auxiliary or second data array block
