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 that appears in intensity mode using different colors.
Snapshot
The currently displayed waveforms can be retained on the screen as snapshot waveforms.
Snapshot waveforms can be saved and loaded.
Clear trace
Displayed waveforms can be cleared.

Specifications
Computation
Two computations can be performed, using MATH1 and MATH2 (only MATH1 on the DLM2022,
DLM2032, and DLM2052).
Available source channels are as follows:
MATH1:
CH1 to CH4
1
MATH2:
CH1 to CH4, and MATH1
The maximum computable record length is as follows:
Standard model:
6.25 M points
/M1(S) option:
25 M points
/M2 option:
62.5 M points
/M3 option:
125 M points
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.
Operators
+, -, *, /, ABS, SQRT, LOG, LN, EXP, P2, SIN, ASIN, COS,
ACOS, TAN, ATAN, PH, DIFF, INTEG, FILT1, FILT2, HLBT,
MEAN, DELAY, BIN, PWHH, PWHL, PWLH, PWLL, PWXX,
FV, DUTYH, DUTYL, DA
Constants
K1 to K4, 0 to 9, PI, e, fs, 1/fs, Exp, Measure
FFT
Two FFT (Fast Fourier Transform) waveforms, FFT1 and FFT2, can be displayed (only FFT1 on
the DLM2022, DLM2032, and DLM2052).
Sources:
CH1 to CH4
2
, MATH1, MATH2
2
Ranges:
Main, Zoom1, Zoom2
FFT Points:
1.25 k, 12.5 k, 125 k, 250 k points (samples the waveform in the above range
using the specified number of FFT points)
Windows:
Rectangular, Hanning, and flattop
Modes:
Normal, Max Hold, Average
On models with the user-defined computation option, the FFT's Type and Sub type settings can
be set as follows:
Type:
LS, RS, PS, PSD, CS, TF, CH
Sub type:
MAG, LOGMAG, PHASE, REAL, IMAG
Reference waveforms
Two reference waveforms, REF1 and REF2, can be displayed (only REF1 on the DLM2022,
DLM2032, and DLM2052).
Saved waveforms and channel waveforms can be loaded into REF1 and REF2.
REF1 uses the MATH1 waveform. REF2 uses the MATH2 waveform. Therefore, REF and MATH
cannot be used simultaneously. Maximum record length at which reference waveforms can be
used is the same as the maximum record length at which computation is possible.
Serial bus signal analysis
3
FlexRay, CAN, CAN FD (ISO 11898-1: 2015 or non-ISO), LIN, CXPI, SENT, PSI5 Airbag, UART,
I2C, SPI, and user-defined serial bus data can be analyzed and displayed.
The DLM2000 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 or
display a list of detailed decoded results. For SENT and PSI5 Airbag signals, trend display is also
possible.
By setting search conditions and performing a search, you can display an expanded waveform with
the detected frame’s or field’s first data byte at the center of the window.
The DLM2000 can analyze and search the waveforms of up to four serial bus signals. The DLM2022,
DLM2032, and DLM2052 can analyze and search the waveforms of one serial bus signal (Serial.
Bus1).
