I measured IdVd curve, and I calculated gm directly from the plot with function derivative(vg,id,1)!!gm in Y data 1. how can I export the new data gm which I just calculated in plot to .mdm files ? Thanks
If your objective is to have the derivative data to be written to an exported *.mdm, you could use the following approach:
1. Define a transform, called for example 'gm', as a Function: derivative to do the calculation. (then on the plot, refer to that transform name gm to add it to plot) 2. Define variable MDM_EXPORT_XFORM_DATA to be TRUE 3. Define variable MDM_XFORM_LIST to be gm (the name of transform calculating the derivative ) 4. After making those changes you can export the Setup to *.mdm.
The *.mdm will then contain the transform data, in this case 'gm'. (you can add additional transforms to be saved..)
Hope this helps. If you have any other questions, please feel free to contact our Technical Support at eesof_support@agilent.com.
Thank you for your reply. But when I look the function "derivative". The description is written as below: "This function has been deprecated. Use the data_deriv function instead for calculating derivatives." But I can not find out the function "data_deriv". Should we use the function "derivative" or "data_deriv"
