Chapter 2: Probing and Selecting the Sampling Mode
Formatting Labels for Logic Analyzer Probes
Positive polarity means that a high voltage is a logic "1".
Negative polarity means that a high voltage is a logic "0".
Changing the label polarity will have the following effects:
• "1" and "0" values flip in the trigger condition.
• Waveforms and bus values (where shown) invert in the Waveform display
tool.
• "1" and "0" values flip in the Listing display tool.
Changing the label polarity does not affect:
• Edge definitions for clock setup and edge terms.
• Symbol definitions for the logic analyzer.
• Activity indicators.
To reorder bits in a label
In cases where buses in the device under test haven't been probed with
consecutive logic analyzer channels, you can reorder the bits in a label.
1. In the Format tab, select the label button whose bits you want to reorder.
2. Choose Reorder bits.
3. In the Change Bit Order dialog:
• To reorder the bits individually, enter the bit that the probe channel
should be mapped to.
• To swap the high and low order bytes or words, select the button Big
Endian to Little Endian at the bottom of the dialog.
• To return to sequentially ordered bits, select the button Default Order
at the bottom of the dialog.
4. Select the OK button.
The label now shows an "R" to indicate that the assigned bit has been
reordered.
