Calling Excel from Your Instrument
Excel can be directly called from the instrument in two ways:
Using a function
Using 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.
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.
How to Select a Parameter Function Call
The Excel Parameter function is selected from the Select Measurement menu, where it appears
in the Custom group.
