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”.  
 
 
 
Math Operation Label 
 
Press MATH  Math  Label  Display to enable or disable the MATH label. 
When “ON” is selected, you can add the MATH label via two modes. 
 
  To Use Preset Label 
Press Preset to select ADD, SUB, MUL, DIV, FFT, AND, OR, XOR, NOT, Intg, Diff, 
Sqrt, Lg, Ln, Exp or Abs. 
  To Edit Label Manually 
Press Label Edit to open the label input interface. You can input the label 
manually. For the details, please refer to the introduction in “
Channel Label”.
