When you set the delay such that the trigger point is on the left side of the
screen, delay time is positive. What you will see at the center of the screen
will be the result of samples taken after the trigger point. They have
occurred in what is referred to as positive time.
Delay time resolution is equal to 2% of the sweep speed setting when using
the knob. When using the pop-up keypad, resolution is 10 ps at sweep
speeds of 99.99 ns/div and faster, and can be set to 5-digit resolution at
sweep speeds of 100 ns/div and slower.
When run mode is set to Repetitive, the valid Delay range is:
Pre-trigger delay range = 16384
×
sample period
Post-trigger delay range is equal to the following:
Time/Div Setting Available Delay
100 ms to 5 s/div 2.5 ks
1 us 50 ms/div 33,500 x (s/div)
1 ns to 500 ns/div 32.7 ms (HP 16533A)
500 ps to 200 us/div 16.3 ms (HP 16534A)
Pre- and post-trigger delay time ranges, as they compare with sweep speeds,
are shown in the table at the end of this chapter.
The default value for the Delay field is 0 s.
