5 Commands by Subsystem
Introduction to
:FUNCtion
Commands
The FUNCtion subsystem controls the math functions in the oscilloscope.
Add, subtract, multiply, differentiate, integrate, square root, 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, and WINDow commands are only useful for
FFT functions. When FFT is selected, the cursors change from volts and
time to decibels (dB) and frequency (Hz).
Reporting the Setup
Use :FUNCtion? to query setup information for the FUNCtion subsystem.
Return Format
The following is a sample response from the :FUNCtion? queries. In this
case, the query was issued following a *RST command.
