disable waveform invert, etc. 
―  Press Start and use   to set the start point of the operation results. 
―  Press End and use   to set the end point of the operation results. 
―  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 0.00 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. 
  Use HORIZONTAL    POSITION and HORIZONTAL   SCALE can also be 
used to adjust the horizontal position and scale of the operation results. 
 
 
“NOT” Operation 
 
Perform logic “NOT” 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 NOT operation of two binary bits are as follows. 
 
Table 6-5 Logic “NOT” Operation 
 
Press MATH  Math  Operator to select “!A”: 
  Press Operation to enable or disable the “NOT” operation function. 
  Press SourceA 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. 
  Press Offset and use   to adjust the vertical position of the operation results. 
  Press Scale and use   to adjust the vertical scale of the operation results. 
  Press Scale Reset to adjust the vertical scale of the operation results to the 
optimal value according to the current configuration.
