Tektronix 2465B Operator's Manual

Operation
Avoid Ambiguous Event Counts
With slow signal transitions, the start event detected by the A Trigger may
also be detected as a delaying event by the B Trigger, depending on SLOPE
and LEVEL settings of the two triggers.
When the time between the start event and the first delaying event is less
than 4 ns. the first delaying event may or may not be counted. In most cases,
the ambiguity can be resolved by choosing appropriate trigger slopes for the
start and delaying events.
To see exactly which event is counted as the first event, select B-Sweep
Delayed-by-Events, pull SEC/DIV out to display the intensified A Sweep, and
set the event count to 1. The intensified zone will show which event is
counted first.
Canceling Menu Functions
To exit from any MEASURE menu, select OFF from the menu or press any
other front panel switch except VERTICAL MODE or MEASURE.
Pressing MEASURE while in a menu cycles HELP text lines through the
bottom line of the readout.
