Specifications
Accumulation
Accumulates waveforms with gradually decreasing intensity for the specified amount of time.
The accumulation time can be set to a value from 100 ms to 100 s or to infinite.
Intensity and color modes can be selected.
Intensity:
Accumulates waveforms using separate channel colors with gradually
decreasing intensity.
Color:
Displays the intensity in intensity mode using different colors.
Snapshot
Retains the waveform that is currently being displayed on the screen as a snapshot waveform.
Snapshot waveforms can be saved and loaded.
Clear trace
Clears all displayed waveforms.

Computation
Four computations, Math1 to Math4, can be performed (Math1 and Math2 on the DLM3022,
DLM3032, and DLM3052).
Sources are as follows:
Math1: CH1 to CH4
1
Math2: CH1 to CH4,
1
Math1
Math3: CH1 to CH4, Math1, or Math2
Math4: CH1 to CH4, Math1 to Math3
The following computation types are available.
Standard model:
Operators +, -, *, Filter, Integ, Count (Edge/Rotary)
User-defined computation (option): Expressions can be created by combining the following
operators and constants.

FFT
Two FFT (Fast Fourier Transform) waveforms, FFT1 and FFT2, (FFT1 only on the DLM3022,
DLM3032, DLM3052) can be displayed.

Range:
Main, Zoom1, Zoom2
FFT Points:
1.25 k, 2.5 k, 12.5 k, 25 k, 125 k, 250 k, 1.25 Mpoints (waveforms in the above
range is sampled down to the specified FFT Points.)

Reference waveforms
Four reference waveforms, REF1 to REF4, can be displayed (REF1 and REF2 on the DLM3022,
DLM3032, and DLM3052).
Saved waveforms and channel waveforms can be loaded into REF1 to REF4.

REF1 to REF4

use the MATH1 to Math4
2
traces, respectively. Therefore, REF and MATH cannot
be used simultaneously.
Serial bus signal analysis
4
FlexRay, CAN, CAN FD (ISO or non-ISO), LIN, CXPI, SENT, UART, I
2
C, SPI, and user-defined
serial bus data can be analyzed and displayed.
The instrument can decode frames, fields, and other information from the waveform displayed
on the screen. Then, it can display the decoded results and the waveform together on the screen
and display and save a list of detailed decoded results . For SENT signals, trend display is also
possible.
If you set search conditions and perform a search, you can display the waveform expanded with the
beginning of the frame, field, or data that meets the search conditions in the center.
The instrument can analyze and search the waveforms of up to four serial bus signals. The
instrument can search up to 50000 points on the selected serial bus signal. (Serial Bus 1 only on
the DLM3022, DLM3032, DLM3052)
