scale is enabled, the instrument will adjust the vertical scale of the
operation results to the optimal value according to the current
configuration.
―
Press fx Operator, fx A and fx B to set the operator and signal sources of
the inner layer operation of Fx operation (please refer to the introduction in
"Fx Operation").
Note: Sens. and Smooth are grayed out and disabled. Sens. is only available
when a digital channel is selected as the source. Smooth is only available for
differential operation.
 You can also use HORIZONTAL POSITION and HORIZONTAL
SCALE to adjust the horizontal position and scale of the operation results.
Fx Operation
MSO1000Z/DS1000Z supports the fx operation function which can achieve more
complex operations.
The procedures are as follows:
1. Split the complex operation
Users can split a more complex operation into inner and outer layers (the inner
layer can only be one of the algebra operations; the outer layer can be one of
the algebra or function operations) according to their needs.
2. Set the operator and signal sources of the inner layer
Press MATH  Math  Options  fx Operator select "A+B", "A-B", "A×B"
or "A/B". Press fx A or fx B to select the source A and source B of the inner layer
operation respectively.
3. Set the operator and signal source of the outer layer
Press MATH  Math  Operator to select the desired operator. The outer
layer supports multiple operations, including A+B, A-B, A×B, A/B, Intg, Diff, Sqrt,
Lg, Ln, Exp and Abs. Then, you can set the result ("fx") of the inner layer
operation as the signal source of the outer layer operation.
For example, Intg(CH1*CH2). The procedure is as follows:
Press MATH  Math  Options  fx Operator to select "A×B". Press fx A to
select "CH1" and press fx B to select "CH2". At this point, the inner layer operation
setting is completed. Press MATH  Math  Operator to select "Intg". You can
set the parameters of the function operation (Intg). Press Operation to select "ON"
and press Source to select "fx".
