! BASIC/IBASIC Programs; Octave Waterfall Dump

! this program is divided into three parts. (1) set up the source,(2) set up

! and take a MEASUREMENT,(3) dump the data out of the instrument and print

! out the information. The information is in dBSLPrms units

! Some items of note.

1. default is 1 engineering unit per volt

2. engineering unit is defined in Pascals

3. 20E-6 pascals = 1 SPL

4. waterfall can only be dumped if the MEASUREMENT is PAUSED

5. Connect the SOURCE to CHANNEL 1

6. Overall power and A-weight Filter data is always outputted

7. Data in the array A(*) is from Oldest to newest data.

8. This is the opposite of the display which has oldest on

! ! !the bottom

! This program will also distinguish between IBASIC and BASIC run
