Importing Arbitrary Waveforms From Files

HP BenchLink/Arb can be used to edit waveforms imported from the HP 34810A BenchLink/Scope application, Mathcad or

Microsoft Excel. Imported files must be in either .CSV or .PRN point/amplitude pair format.

To import a .CSV or .PRN file:

Files from HP BenchLink/Scope or Microsoft Excel previously saved in the .CSV or .PRN file format can be imported into a waveform edit window in the following manner:

1Select File Import... from the Menu Bar. The Open dialog box will be displayed, prompting you to enter the filename of the file you wish to open.

2Choose the appropriate file extension from the file type list, select the

desired file and click the OK button. If the file is displayed in the file list,

5double-click on it to open the file. Click the CANCEL button to abort the command or the HELP button for more information.

3The file will be opened as a new waveform edit window, properly scaled to display the points. The points may be cut and pasted into another waveform edit window if desired.

To import a file from Mathcad:

The Mathcad file must be in a tab-separated X, Y format (.PRN) before it is imported into HP BenchLink/Arb. X values in the data should be sequential. Y values should be between +1 and -1 since

HP BenchLink/Arb will scale the data to ± 1 based on the minimum and maximum values of the data. Use the WRITEPRN function in Mathcad to produce this type of data file. As an example, a file could appear as:

11.0

20.4

3-0.2

4-1.0

5-0.3

60.5

When the file has been saved in the .PRN file format, it can then be imported into HP BenchLink/Arb.
