4 - 54 HOW TO USE THE INSTRUMENT
4.12 PROCESSING FUNCTIONS
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.
