Operating Procedure
Setting the Computation Mode
1. Press SHIFT to activate shift mode.
Functions marked in purple on the panel become active.
2. Press MATH.
3. Press the Mode soft key to select ON or OFF.
These soft keys are not
displayed on the DL1620.
4. Press the soft key corresponding to the channel whose phase is to be shifted.
5. Turn the jog shuttle to set the shifted time.
Explanation
The phase of CH1 to CH4 (or CH1 to CH2 for the DL1620) waveforms is shifted and the
result is displayed. Computation can also be carried out on phase-shifted waveforms.
Allowable Shift Range
The phase can be shifted in the following range.
Time value between –(record length/2) to (record length/2) (resolution: 1/sample rate)
The sample rate varies depending on the record length or T/div setting. For details, see
Appendix 1, “Relationship between the Time Axis Setting, Sample Rate, and Record
Length.”
Notes when Shifting the Phase
If you change the T/div setting after shifting the phase, the shift on the screen does not
change, but the specified time value change in accordance with the T/div setting.
