Waveform Wn
The Waveform command, Wn, is used to select the waveform data which will be
sent when the Analyzer488 is addressed to talk. There are 12 possible waveforms
which may be chosen (W0 to W11). Each waveform consists of 256 readings. A
reading is defined as one data point in the waveform. The format of the readings may
be specified by using the Format (Gn), 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. If waveform 12 is
selected, data from the user waveform buffer will be returned. The graph of each
waveform is shown on the following pages.
SYNTAX: Wn Select waveform n. (n=0 to 12)
W? Returns current waveform selection
