― Press Invert to enable or disable the inverted display function of the

waveform.

― Press Auto Scale to enable or disable the auto scale function. When auto

scale is enabled, the instrument will adjust the vertical scale of the

operation results to the optimal value according to the current

configuration.

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 Display to select “ON”

and press Source to select “fx”.
