Sync mode bug

When NORM sync mode selected, each time triggered the waveform disappears from screen once it shown for a moment. FW: 1.20

Under NORM mode, oscilloscope will scan only when the trigger condition is satisfied, and it will refresh one screen at a time. If it is not triggered, it will not scan.

But it doesn't hold picture until next trigger condition.

If you mean the trigger refresh rate is too low so the waveform doesn't overlap enough for you to see, try to move T0 to the leftmost position for the best view. It has a bug in which the trigger works less frequently depending on the T0 position.

In it's current state the NORM mode is almost useless. DSO means storing oscilloscope and it must store (keep on the screen) the picture until next trigger condition.

I just moved from the old analog oscilloscope and thought this was normal. what a miss.
You're right, the waveform should remain until the next trigger condition.
我习惯使用模拟示波器，所以混淆了一会儿。
没错，数字示波器应该保持屏幕直到下一个触发条件。

The reviewer on the YouTube link below is using 1.20 and does not exhibit any trigger problems as we are getting with 1.22! Please make available 1.20 for downgrade or please hurry your new firmware, because my ds213 is unusable for me with 1.22! https://youtu.be/anLF1Rd6b6A
