Introduction to :FUNCtion Commands

N O T E

The FUNCtion subsystem controls the math functions in the oscilloscope. Multiply (channel 1 x channel 2), subtract (channel 1 - channel 2), differentiate, integrate, and FFT (Fast Fourier Transform) operations are available. These math operations only use the analog (vertical) channels.

To perform analog channel addition, set analog channel 2 to invert and select subtract (channel 1 - channel 2).

The SOURce, 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.
