Can I change the polarity of a bus or signal on my 1680/1690/16900 series logic analyzer?

Yes. To enable this option, go to the Buses/Signals tab of the Analyzer Setup window. Then click the Display button and check Polarity. A new Polarity column will appear in the Bus/Signal table. You can click the button in this column to reverse the polarity for any of the defined buses or signals. The polarity setting affects the display of values and waveforms. When a bus or signal is set to negative polarity, an incoming high voltage will be displayed as a low waveform with a logical value of 0. The polarity is reflected in all places that use values, such as triggers and symbols.
