2.2 Channels and Displayed Waveforms
There are three types of waveform that can be displayed on the DL9000.
• Input waveforms
• Computed waveforms
• Reference waveforms
The reference waveform can be selected from input waveforms, computed waveforms,
and previously stored input or computed waveforms.
The DL9000 provides the following channels.
• Input channels (CH1 to CH4)
• Computation channels (M1 to M4)
By assigning a waveform to each channel, the assigned waveforms can be displayed.
Depending on the channel type, different waveforms can be assigned as follows.
Input channels: Measurement waveforms currently being captured, computed
waveforms
Computation channels: Computed waveforms, reference waveforms
Note
If a computed waveform is assigned to an input channel, it is displayed as MATH5 to MATH8.
Input Waveforms
These are waveforms for measurement input to an input channel.
Computed Waveforms
These are waveforms computed from input waveforms or reference waveforms.
In the calculation equation that can be set in the menu for channels 1 to 4 is fixed, being
the input waveform of the input channel being set. When a calculation is set in the
menu for channels 1 to 4, the data of the channel for which the calculation is set is the
calculation value.
For details of computations, see page 2-24.
Note
To use a calculated result as a source for a different calculation equation, set the calculation
equation in the menu for channels 1 to 4, then use that result (one of channels 1 to 4) as the
source in the separate calculation formula.
Reference Waveforms
Any of input waveforms, other computed waveforms, and previously stored input or
computed waveforms can be selected for display. The history information for the
selected waveform is also read in.
It is also possible to make a separate selection from the history waveforms to display
only one, or to display all of the history waveforms superimposed.
A history waveform refers to any previous waveform stored in acquisition memory.
For details of history waveforms, see Chapter 11.
