Display voltage, current, and power consumption in graph at real time.
Dump
display
Display voltage, current, and power consumption in dump display at
real time.
Save
Save log file data, export in text/CSV/binary for data payload, copy/
paste via a clipboard. (Able to make comments on saved data.)
*VBus logger mode has only the function of saving log files and CSV
outputting.
Print function
Specified ranges of recorded data can be printed.
*VBus logger mode does not have this function.

Additional Memory: HDD or SSD. 30MB plus enough capacity to
record log data.
*1: Bus Reset, Suspend, Disconnect are recorded under the following condition.
Bus Reset
The SEO status of D+/D- signals is detected within a range between 2.5us and 139.8ms
Suspend
A non-communication period not in the SEO status is detected for 3ms or over.
Disconnect
The SEO status of D+/D- signals is detected for 139.8ms or over.
Note: The USB device status may not coincide with the actual bus state of the applicable device at the time of
USB cable connection or disconnection because the D+/D- signals will be unstable.
*2: Display a minus value when VBUS current flows from the device to the host.
