The Trigger readouts shows the trigger source, slope, and the trigger
threshold level. The readout also shows the measured signal frequency. The
trigger readouts for other trigger types show other values. The image shows
the readouts for an Edge trigger.
The horizontal position/scale readouts show the horizontal scale setting
(time per major horizontal graticule division; adjust with the Horizontal
Scale knob) and the sample rate (number of samples per second).
The trigger Delay Mode readout is the time from the T symbol to the
expansion point icon (adjust with the Horizontal Position knob).
Use horizontal position to add delay between when the trigger occurs and
when you actually capture the data. Insert a negative time to capture more
waveform data before the trigger event.
When Delay Mode is off, this readout shows the time location of the trigger
within the waveform record, as a percentage.
The Record Length readout shows how many samples are being stored for
the current waveform records. See Setting the record length on page 77.
