7. The trigger lev
el icon shows the trigger
level on the waveform. The icon color
corresponds to the trigger source color.
8. The trigger readout shows the trigger
source, slope, and level. The trigger
readouts for other trigger types show
other parameters.
9. The top line of the record length/sampling
rate readout shows the sampling rate.
You can adjust it with the Horizontal
Scale knob. The bottom line shows
the record length. You can adjust it by
pushing Acquire and Record Length on
the lower menu.
10. The horizontal position/scale readout
shows on the top line the horizontal scale
(adjust with the Horizontal Scale knob).
With Delay Mode on, the bottom line
shows the time from the T symbol to the
expansion point icon (adjust with the
Horizontal Position knob).
Use horizontal position to insert added
delay between when the trigger occurs
and when you actually capture the data.
Insert a negative time to capture more
pretrigger information.
With Delay Mode off, the bottom line
shows the time location of the trigger
within the ac quisition, as a percentage.
11. The Timing Resolution readout shows
the timing resolution of the digital
channels.
Timing resolution is the time between
samples. It is the reciprocal of the digital
sample rate.
When the MagniVu control is on,
“MagniVu” appears in the readout.
