for trigger. Trig’d: Triggered. Auto: Acquiring untriggered data.
6. The security icon indicates when the I/O ports are disabled.
7. The cursor readout shows time, amplitude, and delta ( Δ ) values for each cursor. For FFT measurements, it shows
frequency and magnitude. For serial and parallel buses, the readout shows the decoded values.
8. The trigger level icon shows the trigger level on the waveform. The icon color corresponds to the trigger source color.
9. The trigger readout shows the trigger source, slope, and level. The trigger readouts for other trigger types show other
parameters.
