status. Status conditions are:
PrTrig: Acquiring pretrigger data
Trig?: Waiting for trigger
Trig’d: Triggered

6. The cursor readout shows time,
amplitude, and delta (
Δ ) values for each
cursor.
For FFT measurements, it shows
frequency and magnitude.
For serial buses, the readout shows the
decoded values.
