4.12 PROCESSING FUNCTIONS

MATH

Most oscilloscopes, including most Digital Storage Oscilloscopes, limit their capabilities to the display of amplitude (in volts), versus time.

In addition to those traditional oscilloscope functions, this range offers capabilities to mathematically change the contents of each memory location. To do so, the functions under ’MATHEMATICS’ allow you to calculate new waveforms from existing other traces serving as input data.

If your oscilloscope is equipped with the MATH + option, more functions are available than the ones described in this section. Additional information on the additional functions is described in a separate manual.

The section below describes the mathematical functions implemented in the standard oscilloscopes versions.

Two mathematical functions MATH 1 and MATH 2 can be used as two independent processes. They can be used in series or in parallel. The result of MATH 1 is always stored in memory location ’m1’.

The result of MATH 2 is always stored in memory location ’m2’. When used for mathematical functions, existing memory locations are overwritten. (Use the ’Copy’ function to save important traces in another memory location, before using the mathematical functions.)

STANDARD SETTING

Start with the standard setting to ensure that you have the correct start condition.

-Simultaneously press the STATUS and TEXT OFF keys.

-Connect the Probe Adjust signal to channel 1.

-Press AUTOSET.

The Probe Adjust signal now supplied to the input is a square wave with a lower level of 0V and a top level of 600 mV.
