Introduction to
:FUNCtion
Commands
The FUNCtion subsystem controls the math functions in the oscilloscope. Add,
subtract, multiply, and FFT (Fast Fourier Transform) operations are available.
These math operations only use the analog (vertical) channels.
The SOURce1, DISPlay, RANGe, and OFFSet commands apply to any function.
The SPAN, CENTer, VTYPe, and WINDow commands are only useful for FFT
functions. When FFT is selected, the horizontal cursors change from time to
frequency (Hz), and the vertical cursors change from volts to decibel (dB).
Reporting the Setup
Use :FUNCtion? to query setup information for the FUNCtion subsystem.
