3. When the "Wave hop" mode is set, the RAM bank and RAM size bits
(Table C-2) are not used.
The C program WAVE_HOP.C is in directory "CPROG", and the
QuickBASIC program WAVE_HOP.BAS is in directory "QBPROG" on
the example program disk HP P/N E1340-10036.
The following program generates a linear sweep from 1 kHz to 10 kHz in 5
seconds.
