3. Push the Data, Marker1, or Marker2 side button to specify which data to
invert.
4. Push the Exec side button to vertically invert the cursor-to-cursor data you
have specified in Step 3.
The Clip... command sets the edit area waveform data maximum upper or lower
signal level to a specified value.
Do the following steps to clip the waveform data:
1. Move the cursors to specify the edit area to clip.
2. Push Operation (bottom)
!Clip... (pop-up)!OK (side).
3. Push the Clip side button to specify the portion of level to be clipped. Select
either the Upper or Lower. Upper refers to all signal data located above the
origin, and lower refers to all signal data located below the origin.
4. Push the Level side button and specify the clip level using the general
purpose knob or numeric keys.
5. Push the Exec side button to clip the waveform data.
The Shift Register Generator... command specifies a shift register to generate
pseudo-random pulses with the value of 1 or 0 that replace the waveform data in
the edit area. The pseudo-random shift generator consists of a user-definable
register size (1 to 32 bits) and a user-specified number of feedback taps that do
an XOR operation between a specified register bit and the register output.
NOTE. XOR (exclusive OR) is a boolean logic operation that outputs one if two
input values are different and outputs 0 otherwise.
Figure 3–6 shows an example of the pattern generated for a 3-bit register with an
initial value of 101 and a single tap on register bit 2.
