Number of Samples
The various math packages can process samples as follows:
Excel 65,535 samples
Mathcad 5 MS
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
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.
Please Note the Following:
• 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.
