Large capacity memory up to 250 Mpoints
Long memory is necessary to keep high speed sample rate in long term measurement.
<Basic Formula> Measuring time = Memory length/Sample rate
If 250 Mpoints (Memory expansion option /M3) is installed, Max. 0.2 sec waveform can be captured even at 1.25 GS/s sample rate when
taking 2 ch measurements in Single mode.
Zoom & search function
With 2 different zoom location at the same time and variety of search function lets you pull out and display necessary data effectively.
Zoom two locations simultaneously
Because the DLM2000 series lets you set zoom factors
independently, you can display two zoomed waveforms with
different time axis scales at the same time. Also, using the Auto
Scroll function, you can automatically scroll waveforms captured
in long memory and change the zoomed location. With Auto Scroll
you can choose forward, backward, fast-forward, scroll speed, and
other control options.
Waveform search using edge criterion
Zoom Search function
This function searches captured waveforms in the long memory
and displays waveforms that meet the search criteria in the zoom
area. The locations of the found waveforms are marked on screen
( shows the current location).
• Waveform search criteria
Edge, edge (with conditions), state pattern, pulse width, state width,
serial bus (only on models with the serial bus analysis option)
Detailed waveform measured for 20 seconds are
shown in 20 milliseconds and 100 microseconds
span.
Waveform in 250 Mpoints can be magnified
up to × 200000.

Caution is needed when using oscilloscope that does not have enough memory, which
can cause lack of sample rate and possible failure capturing accurate waveform.
Sample rate is too low.
Sample rate is fairly high.
