Power supply analysis
feature (/G3 or /G4 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)”

IEC 61000-4-7 Ed. 2
• Joule integral (I

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 four 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.
Screen Capture Data Printing and Saving
Item
Specifications
Built-in printer
(/B5 option)
Prints screen captures with the built-in printer.
Print mode: Select from the following:
Hardcopy: Prints the displayed screen image.
Normal: Prints only the waveform area of the displayed screen image. The menu is not printed. If
cursor measurements or automatically measured results are displayed, they are printed
below the waveform area.
Long: Prints a screen capture whose time axis is magnified 2 to 10 times. The menu is not
printed. If cursor measurements or automatically measured results are displayed, they are
printed below the waveform area.
Network printer
Prints screen captures on an external printer via Ethernet.
Color can be turned on or off. Supports Epson inkjet printers, HP inkjet printers, and HP laser
printers.
Print mode: Select from the following:
Hardcopy: Prints the displayed screen image.
Normal: Prints only the waveform area of the displayed screen image. The menu is not printed. If
cursor measurements or automatically measured results are displayed, they are printed
below the waveform area.
File
Saves screen capture data to the specified storage medium using one of the following save modes.
The storage medium can be set to internal memory or USB storage.
Output data format can be set to PNG, BMP, or JPEG. Available color settings are OFF, ON, ON
(Rev), and ON (Gray).
Save mode: Select from the following:
Hardcopy: Saves the displayed screen image.
Normal: Saves only the waveform area of the displayed screen image. The menu is not saved. If
cursor measurements or automatically measured results are displayed, they are printed
below the waveform area.
Wide: Saves a screen capture whose time axis is magnified twice. The menu is not saved. If
cursor measurements or automatically measured results are displayed, they are printed
below the waveform area.
