―
Press Invert to enable or disable the inverted display function of the
waveform.
― Press Sens. and use to set the sensitivity of the digital signal converted
from the analog signal on the source. The setting range is from 0 Div to
0.96 Div.
― 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.
― 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: Smooth is grayed out and disabled. It 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.
"XOR" Operation
Perform logic "XOR" operation on the waveform voltage values of the specified
sources point by point and display the results. In operation, when the voltage value
of the source channel is greater than the threshold of the corresponding channel, it is
regarded as logic "1"; otherwise logic "0".
The results of logic XOR operation of two binary bits are as follows.
Table 6-4 Logic "XOR" Operation
A B A^B
0 0 0
0 1 1
1 0 1
1 1 0
Press MATH  Math  Operator to select "A^B":
 Press Operation to enable or disable the "XOR" operation function.
 Press SourceA and SourceB to select the desired channels (CH1-CH4 or
D0-D15).
―
If source A selects any channel in CH1-CH4, press Thre.A and use set
the threshold of source A in logic operation. If source A selects any channel
in D0-D15, Thre.A will be hidden automatically.
―
If source B selects any channel in CH1-CH4, press Thre.B and use set
the threshold of source B in logic operation. If source B selects any channel
in D0-D15, Thre.B will be hidden automatically.
