What role does the FNIRSI-1013D oscilloscope play in repairing ASIC miner hash board?

FNIRSI-1013D oscilloscope is a flat digital oscilloscope with dual channels, 100MB bandwidth and 1GS sampling rate. When we repair the hash board, we can use FNIRSI-1013D oscilloscope to test the signal waveform of ASIC chip, judge whether the ASIC chip is normal, quickly find faults and deal with them, and achieve the purpose of repair.

FNIRSI-1013D features:

1. Large touch LCD display.

2. Three trigger modes: automatic, single and normal, widely used.

3. One-key automatic adjustment function, short adjustment time.

4. Two input channels, wide applicability, each with built-in high-voltage protection module, can withstand voltage input up to 400V, intelligent anti-burning.

5. USB interface (5V/2A).

Steps to use FNIRSI-1013D:

Prepare tools: ASIC miner test fixture (such as PicoBT tester), hash board to be tested, adjustable voltage PSU, cooling fan, FNIRSI-1013D oscilloscope

1. Turn on the oscilloscope, touch the screen to set the language, probe mode, amplitude and frequency values, and then insert the oscilloscope probe. Different models of hash board require different amplitudes and frequencies. Most hash boards are suitable for the value of "1V, 10μs".

2. Set the voltage value of the adjustable voltage PSU, which should match the voltage value required by the tested hash board. Connect the adjustable voltage PSU related cable to the hash board.

3. Clamp the oscilloscope probe to the negative pole of the hash board. The clamp needs to be clamped tightly. If the clamp is loose during this test, it may damage the oscilloscope.

4. Place the hash board above the cooling fan, turn on the PicoBT tester, and press the test button.

5. Use the oscilloscope probe to measure the signal waveform on the hash board, and observe the waveform on the screen to determine whether the ASIC chip signal is normal.

The FNIRSI-1013D oscilloscope, with its fast and accurate signal waveform measurement, allows us to greatly improve the efficiency of repairing hash boards.
