Memory Depth/Record Length
[Run/Stop] versus [Single]
When the oscilloscope is running, the trigger processing and update rate are optimized over the
memory depth.
Single
Single acquisitions always use the maximum memory available—at least twice as much memory
as acquisitions captured in Run mode—and the oscilloscope stores at least twice as many
samples. At slow sweep speeds, the oscilloscope operates at a higher sample rate when Single is
used to capture an acquisition due to the increased memory available. To acquire data with the
longest possible record length, press the [Single] key.
Running
When running, versus taking a single acquisition, the memory is divided in half. This allows the
acquisition system to acquire one record while processing the previous acquisition, dramatically
improving the number of waveforms per second processed by the oscilloscope. While running,
maximizing the rate at which waveforms are drawn on the display provides the best
representation of your input signal.
