two vertical dashed lines: cursor 1 has single dashes and
cursor 2 has double dashes. The time difference between
them is displayed as ∆
T. Select voltage and timing cursors
together (
V+T). Note that when CONTROL is set to TIME, the
three bezel controls adjust timing cursors; when set to
VOLT,
they adjust voltage cursors.
Select markers
(MARK). The markers appear as three dashed
lines; marker 1 has long singl e da shes, marker 2 has double
