When the Acquisition Mode Is Set to Average
Set the number of waveform acquisitions.
Set the attenuation constant.
Set the trigger mode.
Set Acquisition Mode to Average.
Set the record length.
Set the time base (Internal, External).
External
Set the pulse/rotation.
Setting the Acquisition Mode (Acquisition Mode)
Normal: Displays waveforms without processing the sampled data. Set the waveform
acquisition count.
Envelope: Displays waveforms in envelope mode. Set the waveform acquisition count.
Average: Displays averaged waveforms. Set the attenuation constant or the number of times
to average.
When the acquisition mode is set to Average, the trigger mode cannot be set to
Single, Single N, or On Start.
SSD recording cannot be used either.
Setting the Trigger Mode (Trigger Mode)
The trigger mode determines the conditions for updating the displayed waveforms. The operation is
the same as for Trigger Mode of the MENU key for trigger.
► sec 4.1for trigger)
You can select from the following options.
Auto, AutoLevel, Normal, Single, Single N, On Start
Setting the Time Base (Time Base)
Internal: The internal clock signal is used for the time base (the TIME/DIV setting is valid).
External: An external clock signal is used for the time base (the TIME/DIV setting is invalid).
Specify a pulse count that corresponds to one rotation (or one cycle) of mechanical
movement (Pulse/Rotate).
Setting the Time Scale
Turn the TIME/DIV knob. The new TIME/DIV will be applied the next time waveform acquisition is
started.
