Oscilloscope Common Menus; Run/Stop Options - HP 1660CS-Series User Manual

Oscilloscope Common Menus

The following options apply to all of the oscilloscope menus.

Run/Stop options

There are three ways you can manually run and stop the oscilloscope: the
Autoscale menu, the Run and Stop keys, and the Run/Stop field.
Single and Repetitive modes
Single mode acquisition fills acquisition memory once with 8000 samples of
the input waveform, automatically stops running, then displays the contents
of acquisition memory. Each 8000-sample waveform record is acquired in a
single acquisition. Each channel has a memory capacity of 8000 samples.
Repetitive mode acquisition fills acquisition memory with 8000 samples of the
input waveform on continuing acquisitions, with each new acquisition
overwriting the previous. The display is updated each time a new acquisition
is made. Repetitive mode continues acquiring data in this manner until you
select the Stop field. As in single mode, each 8000-sample waveform record
is acquired in a single acquisition.
Autoscale run
Select the autoscale field on the screen, then choose Continue from the
pop-up menu. When autoscaling is complete, the oscilloscope automatically
starts running.
If you have been using the Run field to initiate your runs, the oscilloscope will
run in the mode (single or repetitive) that was last chosen using the Run
options. If no run mode has been chosen prior to choosing autoscale, the run
mode defaults to single mode.
If you have been using the Run key to initiate your runs, the oscilloscope will
run in single mode.
See Also "Autoscale" later in this chapter for information on how the autoscale
algorithm works.
