Item Specifications
GO/NO-GO determination A specific action can be executed when the GO/NO-GO result is NO-GO.
You can set the number of times to execute the action in terms of the number of waveform
acquisitions or the number of determinations.
Up to four conditions can be set, and the four
4
conditions can be combined using AND or OR logic
to perform determination.
Reference condition can be set to whether the source waveform enters the reference range (IN),
moves outside the search range (OUT), or don't care (X).
The following four reference range types are available.
Rect-Zone: Rectangular zone. FFT waveforms cannot be used.
Wave-Zone: Waveform zone. XY and FFT waveforms cannot be used.
Polygon-Zone: Polygonal zone. FFT waveforms cannot be used.
Parameter: Zone between the upper and lower limits of one waveform parameter.
Actions
Beeping, screen capture data printing or saving, waveform data saving, mail transmission

Power supply analysis
feature (option)
You can select and execute the analysis feature or power measurement feature.
Analysis feature: Two of the following analyses can be executed simultaneously.
• Switching loss analysis (SW Loss):
The total loss and the switching loss can be measured. Items such as power waveforms and
measured values can be displayed, and statistics can be computed. The items whose switching
losses can be measured automatically are listed below.
Wp, Wp+, Wp–, Abs.Wp, P, P+, P–, Abs.P, Z
• Safe Operating Area (SOA):
An X-Y display can be created with voltage input plotted on the X-axis and current input plotted
on the Y-axis.
• Harmonic analysis (Harmonics):
Simple comparisons can be made between the harmonics and standard limits.
IEC 61000-3-2 Ed. 2.2, “Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for
harmonic current emissions (equipment input current ≤ 16 A per phase)”
EN 61000-3-2 (2000)
IEC 61000-4-7 Ed. 2
• Joule integral (I
2
t):
Items such as Joule integral waveforms and measured values can be displayed, and statistics
can be computed. The item whose Joule integral can be measured automatically is shown below.

Power measurement feature: The power of up to two circuits can be measured simultaneously.
The items that can be measured automatically are shown below.
U+pk, U–pk, Up-p, Udc, Uac, Urms, Umn, Urmn, Avg Freq (of voltage), I+pk, I–pk, Ip-p, Idc, Iac,
Irms, Imn, Irmn, Avg Freq (of current), S, P, Q, Z, λ, Wp, Wp+, Wp–, Abs.Wp, q, q+, q–, Abs.q
The auto deskew feature automatically deskews the time difference between the voltage and
current waveforms. Auto deskew uses voltage and current signals of the deskew signal sources
(701935 or 701936; sold separately) that are received through probes connected to voltage
channels and current channels, respectively. For information about the deskew range, see
“Deskewing” described earlier.
1 CH1 and CH2 on the DLM2022, DLM2032, and DLM2052.
2 CH1, CH2, and MATH1 on the DLM2022, DLM2032, and DLM2052.
3 FlexRay, CAN, CAN FD, LIN, CXPI, SENT, PSI5, UART, I2C, and SPI are options for 4-channel models.
4 Two on the DLM2022, DLM2032, and DLM2052.
5 On models with the Ethernet option.
