Math Functions

Without the Measurement/Storage module installed, addition and subtraction

are the only math operations provided. In addition to the limited selections,

the single function is performed on the pixel position of the data on the

screen.

With the Measurement/Storage module installed, two functions define up to

six operations that create mathematically altered waveforms (not pixel math.)

•

Function 1 will add (+), subtract (–), or multiply (*) the signals acquired

on vertical inputs 1 and 2, then it will display the result as F1.

•

Function 2 will integrate, differentiate, or perform an FFT on the signal

acquired on input 1, input 2, or the result in F1; then it will display the

result in F2.

The vertical range and offset of each function can be adjusted for ease of

viewing and measurement considerations. Each function can be displayed,

measured (with cursors), stored in trace memory, or output over the

interface.
