HPBASIC Programming Example

The following programming example was developed using HPBASIC for
Windows. It was tested on an HP 8924C with firmware rev A.02.26.

10 ! re-save "c:\hpbasic\app_note\FER_AWGN"

20 ! This program implements CDMA FER test with AWGN.

30 ! This closely follows T38 from the 83217A Software.
