Read the X-axis values in the block into the array in binary.

Read the line feed character.

Tell the analyzer to output the Y-axis values for the waterfall.

Read the header of the Y-axis values data block.

Read the "#n" to determine how many digits are in the byte count.

Read the number of bytes.

Use the number of bytes to determine the number of data points. Divide the number of bytes by

Re-dimension the array so it is the same size as the data block being read. This allows the data

to be read in the fastest possible manner.

Read all the Y-axis values in the block into the array in binary.

Read the line feed character.

Limits the range of values. When an octave band has no energy, the value is

- ◊ dB and the large negative number (-3.40E38) appears in the data block.

These statements restrict the image statements to the ± 1000 range.

Start the array at 0.

Any values < -99, set to -99. This sets a minimum level.

Any values > -99, set to -99. This sets a minimum level.
