20. Check VAR TIME/DIV Range
a. Set the time-mark generator for 5 millisecond time
marks and connect through a 42-inch 50-ohm BNC cable,
to a 50-ohm BNC termination, to CH 1 input.
b. Set A TRIGGER LEVEL for a stable triggered
display, then set VAR TIME/DIV fully counterclockwise.
c. CHECK—That VAR TIME/DIV UNCAL light is il-
luminated.
d. CHECK—For at least 6 time marks between first and
last graticule lines.
e. Return VAR TIME/DIV control to calibrated detent.
