Problems with FRD Frequency Response Combiner

FrancoB · 2nd August 2008, 04:16 PM

I'm having problems generating minimum phase from my .frd file.

It's generating errors from the moment I press the 'Extract Minimum Phase' button. The rfcerr.log is growing very rapidly with 'Subscript out of range' errors.

I have the file attached.

I'm running Microsoft Office 2003 SP3.

Anyone?

Maybe someone could generate minimum phase for the file with some other tool and post it back?

Your help is highly appreciated!

I just downloaded your file. The first line is not data, it is a *. The frd requires that no comment/non-data lines be in the file IIRC. It also has two extra lines at the end with tabs. These may be a problem also. Be sure all lines are only data lines and try it again.

As Dave said.

No whitespace at the beginning or end of the file. I extracted HBT phase fine using your file once I removed the comments and whitespace at the end.

When you load the FRD file - it should show you the start and end frequency. In your case the end frequency was missing because of the whitespace.

Dave,

What's wrong with your Scan Speak 6600 .frd file?

That one doesn't seem to work?

Cheers,

Frank
