YOKOGAWA DLM5034

6-14
IM DLM5058-03EN
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 on the basis of the number of waveform
acquisitions or the number of determinations.
Up to eight conditions
1
can be set, and Determinations can be made on the AND or OR of eight
conditions.

The following five search modes are available.
OFF: No conditions.
Rect-Zone: Rectangular zone. Cannot be used on FFT waveforms.
Wave-Zone: Waveform zone. Cannot be used on XY or FFT waveforms.
Polygon-Zone: Polygonal zone. Cannot be used on FFT waveforms.
Parameter: Zone between the upper and lower limits of one waveform parameter.
The reference is either the source waveform entering or exiting the reference range.
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: One of the following analyses can be executed.
• Switching loss analysis (SW Loss):
The total loss and the switching loss of N cycles can be measured. Items such as power
waveforms and measured values can be displayed, and statistics can be computed. The
following five locations can be displayed with indicators: the Turn On start and end points of the
first found cycle, the following Turn Off start and end points, and the following Turn On start point.
The conduction loss computation method can be selected from the following:
U × I
RDS (on) × I
2
VCE (sat) × I
The items whose switching losses can be measured automatically are listed below.
P: Turn On, On, Turn Off, Total
Wp: Turn On, On, Turn Off, Total
In addition, statistical processing can be applied to the above items. For details on statistical
processing, see “Statistical processing of waveform parameters,” described earlier.
• 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 harmonic current emission
standard limits. THD and RMS can be displayed.

In addition, statistical processing can be applied to the above items. For details on statistical
processing, see “Statistical processing of waveform parameters,” described earlier.
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
(701936; sold separately) that are received through probes connected to voltage channels and
current channels, respectively.
For information about the deskew range, see “Deskewing” under “Vertical and Horizontal Control”
described earlier.
