1.
Check Horizontal Display Modes (A, A INTEN,
ALT, and B).
a. Use a 50
12
BNC cable to connect 200 ns time mark-
ers from the Time-Mark Generator to the CH 1 OR X input
connector.
b. Adjust the TRIGGER LEVEL control as necessary for
a stable signal display.
c. Pull the SEC/DIV knob out and set the B TRIGGER
MODE to RUN AFT DLY.
NOTE
On CTT instruments, rotate the A REF OR DLY
POS control for the specified delay. As the control is
rotated, the readout delay value will be followed by
the word
"SET".
This value shows the approximate
delay. A few seconds after control movement has
stopped, the word "SET" will disappear and the
readout delay value as measured by the CTT will
appear. This is normal operation and not cause for
concern.
d.
Set the A REF OR DLY POS control for a DLY
readout of approximately 1000 ns.
e. VERIFY—An intensified zone appears on the
displayed signal near graticule center. The INTENSITY
control may need adjustment.
