1780R-Series Operator’s Manual

If OTHER was selected on Step 1, this step allows the 1780R-Se-

ries instrument to determine the pulse width and adjust the

readout accordingly.

a. Voltage cursors are automatically set to 50% of the

amplitude entered in step 2.

b. Timing cursors are enabled and appear as bright-up dots

on the display. Large knob now controls timing cursor

position.

c. Adjust Timing Cursor 1 to the point where the pulse signal

intersects the approximate 50% amplitude level identified

by the Voltage Cursor.

d. Adjust Timing Cursor 2 to the point where the opposite

side of the pulse signal intersects the Voltage Cursor. See

Figure 4–8.
