The number of samples that MATLAB can process is determined by memory option, as
follows:
Memory Length System DRAM Buffer Length
STD, S, M 256 MB 40 MB
L, VL 512 MB 200 MB
XL 1 GB 400 MB
XXL 2 GB 400 MB
Calling Excel From Your Instrument
Calling Excel Directly from the Instrument
Excel can be directly called from the instrument in two ways:
Using a function
F1 through Fx The number of
math traces available depends
on the software options loaded
on your scope. See
Specifications.
Excel returns a waveform
Using a parameter
P1 through Px The number of
parameters available depends
on the software options loaded
on your scope. See
Specifications.
Excel returns a parameter
In both cases, one call to Excel can use two separate waveforms as input.
Notes:
Excel has a calculation algorithm of 64,000 points (32,000 if you have created a chart in Excel). Therefore, make sure that
your acquisition has less than this number of points if you are going to use an Excel calculation.
To use this capability, you must have the LeCroy XMAP software option and Excel loaded in your instrument. Select
Minimize from the instrument's File menu to access the Excel program directly.
How to Select a Math Function Call
The Excel math function is selected from the Math Operator menu, where it appears in the
Custom group.
