waveform()

waveform( dso_id, [channel [,np [,sparsing [, offset]]]]), wf()

Waveform() reads the LeCroy oscilloscopes. The arguments of this function are all evaluated as integer expressions:

channel

The channel number, one of (1,2,3,4,ALL,12,123, TA, TB, TC, TD), default is all channels.

np

The number of samples to be read [1,100000], default 1000.

sparsing

Read every n$th$ point, default 1 (all points).

offset

First point, default 0.

The result is stored in the SCAN lc584_c$i$ (i from [1,4]).

The number of data points np may also be greater than 100000. In this case the data is written into a file. The file name is created using the symbol generic_scan_name with the extension .bin.

e.g.:
* = waveform()
