Explanation
You can define up to four original expressions.
Expressions (Expression)
Define expressions by combining computation source waveforms and operators.
You can enter up to 128 characters.
Computation Source Waveforms
You can use the following waveform data.
Menu Item Description
C1 to C4 CH1 to CH4
M1 to M3 You can use M1 when Setup Trace is set to M2. You can use M1 and M2 when Setup Trace is
set to M3 or M4. You can use M1 to M3 when Setup Trace is set to M4.
T Amount of time elapsed from the screen’s left edge
Operators
You can combine the following operators to define expressions.
