Getting Acquainted with the Oscilloscope
9.
The trigger readout shows the trigger source, slope, and level. The trigger
readouts for other trigger types show other parameters.
10.
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.
11.
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 acquisition, as a percentage.
12.
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.
13.
Measurement readouts show the selected measurements. You can select up to
eight measurements to display at one time. A
symbol appears instead of
