TDS3000C Series Oscilloscopes
Electronics engineers may discover that a wide
array of unintentional electrical events will make
a difference in how circuits function in the real
world. To characterize these events, engineers
can measure criteria such as overshoot, ringing,
ground bounce, cross talk, and other signal
integrity issues. The TDS3000C Series’ cursors
and automatic measurements can be used to
take such measurements.
To make signal integrity measurements
using cursors:
1. Press the
Cursor
button.
2. Press the
Function
menu button.
3. Press the
H Bar Units
(or
V Bar Units
) menu
button to select
H Bar
(or
V Bar
) cursors.
4. Place one cursor, as desired, using the
general-purpose knob.
5. Press the
Select
button.
6. Place the other cursor, as desired, using the
general-purpose knob.
7. View the measurement (between cursors, or absolute)
on the upper right corner of the display.
D
readouts indicate the difference between the cursor positions.
For H Bar cursors, @ readouts indicate the location of the active cursor relative to zero volts.
For V Bar cursors, @ readouts indicate the location of the active cursor relative to the trigger point.
