Computation
Eight computations, Math1 to Math8, can be performed (Math1 to Math4 on the DLM5034 and
DLM5054).
Sources are as follows:
Math1: CH1 to CH4
Math2: CH1 to CH4, Math1
Math3: CH1 to CH4, Math1, Math2
Math4: CH1 to CH4, Math1 to Math3
Math5: CH5 to CH8
Math6: CH5 to CH8, Math5
Math7: CH5 to CH8, Math5, Math6
Math8: CH5 to CH8, Math5 to Math7
The following computation types are available.
Standard model:
Ope, ‒, *, Filter, Integ, Count (Edge/Rotary)
User-defined computation (option): Expressions can be created by combining the following
operators and constants.
Operators

Measure
FFT
Four FFT (Fast Fourier Transform) waveforms, FFT1 to FFT4, (FFT1 and FFT2 on the DLM5034
and DLM5054) can be displayed.
Source:
CH1 to CH8,

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.)
Window:

Normal, Max Hold, Average
If the user-defined computation option is installed, The following types and sub types can be
selected for the FFT.
Type:
LS-, RS-, PS-, PSD-, CS-, TF-, CH-

Reference waveforms
Eight reference waveforms, Ref1 to Ref8, can be displayed (Ref1 to Ref4 on the DLM5034 and
DLM5054).
Saved waveforms and channel waveforms can be loaded into Ref1 to Ref8.

Serial bus signal analysis
4
FlexRay, CAN, CAN FD (ISO or non-ISO), LIN, CXPI, SENT, PSI5 Airbag, 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 and PSI5 Airbag 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.
1 CH1 to CH4 for the DLM5034, DLM5054
2 Math1 to Math4 for the DLM5034, DLM5054
3 Ref1 to Ref4 for the DLM5034, DLM5054
4 FlexRay, CAN, CAN FD, LIN, CXPI, SENT, PSI5 Airbag, UART, I
2
C, and SPI are options.
