d) Insert a closing square bracket using the "]" key.
The resulting expression could be, for example: m[V]
6. To perform a rescaling function, proceed as follows:
a) Select the rescaling function using the "ax+b" key.
b) Behind the left bracket, insert the signal source that is to be rescaled using one
of the following keys:
● "Ch" for a channel
● "Math" for a math function
● "Ref" for a reference waveform
● "Meas" for a measurement
c) Insert a comma using the "," key.
d) Insert the "a" value, i.e. the scaling factor, using the number keys.
e) Insert a comma using the "," key.
f) Insert the "b" value, i.e. the scaling offset, using the number keys.
g) Insert the closing bracket using the ")" key.
The resulting expression could be, for example: rescale(Ch1Wfm1,3,4)
6.2.2.2 Advanced Formula Editor
Using the formula editor you can define math functions freely, using a large selection of
operators and signal sources. For a procedure on using the editor, see chapter 6.2.2.1,
"Defining a Formula in the Advanced Formula Editor", on page 187.
The following tables describe the buttons of the formula editor and their usage.
