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:
1 Select 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.
2 Choose 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,
double-click on it to open the file. Click the CANCEL button to abort the
command or the HELP button for more information.
3 The 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.
