SPECTRAL DISPLAY (v2.0.7 or later)
Path: / STATUS SPECTRAL-DISPLAY
Type: Executable
Syntax: SPECTRAL-DISPLAY
Notes: SPECTRAL DISPLAY plots the signal's frequency components in a graphical manner
similar to a spectrum analyzer. Use the Spin Knob to adjust frequency. Soft keys
A/B change step size. Soft keys C/D change vertical scale. Press PREV to exit. The
M&C command outputs spectral data using the following format:
HEADER: freq, Sig, C/No, BW, Scale(CR)
BODY: 256 encoded data points(CR)
FOOTER: Elapsed Time in ms.(CR)
Each data point is 1 to 64, encoded as a single character (ascii 49 to 112)
