Board inspection jig
The one in the photo is designed for an engine starter, but the It can be designed according to the test contents (required specifications) of the board, and the test can be It is possible to simplify it. The outline of the operation is as follows.
Operation overview
■PC→Supplying signals (power, test waveform, etc.) to the jig
■Jig → Get signal (test results) from PC
■Test result display and management on the PC side
I2C アナライザー
A device that sets and reads data to an I2C device, and sends specified data. You can streamline debugging work during the development stage of devices that use the I2C bus. It has a compact exterior, can be powered by a battery, and has excellent portability.
※I2C…Serial bus used for communication between each device on hardware

DIMM checker
A device that can inspect four memory cards at the same time. This leads to a much shorter time than testing on an actual machine. The LCD menu display allows easy operation. The inspection result is instantly displayed on the LED, and the defective area is displayed on the LCD. Test results can be sent to a computer and test data can be stored. By simply replacing the socket, you can test most types of memory such as SIMM, flash, and memory cards. (Optional specifications)
