Phase Shifted Addition, Subtraction and
Multiplication
Function
This function lets you shift the waveform from one channel (phase shift) and then add, subtract,
or multiply the shifted waveform against the waveform on another channel. Channel allocations
are as follows.
Math1 (Phase) CH1 and CH2; or CH1 and CH5
Math2 (Phase) CH1 and CH3; or CH1 and CH7
Note
Addition and subtraction types differ from those available in basic mode(page 9-10).
Allowable shifting range
You can phase-shift the waveform up to half the record length (record-length/2) in either
direction along the time axis, in steps of {1/sample-rate}. For information about the relation
between sample rates, record lengths, and T/div settings, see Appendix 1.
Points for attention when phase shifting
If T/div is changed after shifting the phase, the amount of the shift does not change on the
screen, and T/div changes with the set time value.
