Invert channel guidelines
This topic describes how the channel Invert function interacts with other instrument settings.
Settings that change when Invert is set to On or Off:
•
The instrument clears acquisitions and restarts triggering
• All persistence information resets/clears, including all waveform statistics, etc
• All associated views and derived results change. For example, XY view, cursor readouts, measurement results, search results, math,
bus decode, and so on, all change to reflect the current Invert setting
Settings that change when Invert is set to On:
• The instrument adds a down arrow to the title row of the channel badge to indicate inverted mode
• The channel Offset value reverses polarity
• The trigger level value reverses polarity
• The trigger level indicator moves to the inverted value and the trigger level bar appears momentarily to show the new level
• The trigger Slope indicator on the Trigger badge and in its menu changes to the opposite edge (Rising to Falling, or Falling to Rising).
If the Either edge mode is selected then slope mode does not change
Settings that don't change when Invert is On:
• The channel Vertical scale does not change
• The channel Vertical position knob rotation direction does not change
