New bench scope - Fnirsi 1014D, 7", 1GSa/s
motomanual:
I recently purchased a Fnirsi 1040d and I need to ask the users of this instrument if it is normal that the trigger does not activate when setting times greater than 10msec in Normal and Single mode?
Is it a limitation of the instrument or am I not using it correctly?
Thanks everyone!

@motomanual see here for an answer to your question.

Here is a video of someone comparing the FNIRSI-1014D to the Rigol DS1202Z-E.
He finds a lot of limitations of the 1014D, among one of them being the power supply ripple seeping through, I also found during the writing of the open source firmware.
The limitations found are nothing new to ones familiar with the threads on this forum about the scope, but still fun to hear him make conclusions about them.

Hello everyone. I bought a burnt 1014D at an auction. Someone supplied 12V. I replaced the broken stabilizer and op-amp chips, updated the firmware. The oscilloscope started up, there is a response to input signals and adequately responds to all buttons and knobs. But there are still two problems:
1. The FPGA clock generator chip burned out. I would like to ask you to take oscillograms and measure the frequency of the signals at pins 9, 10 of the MC5351M chip. Need a two-channel oscilloscope to see the phase relationship of the signals.
2. The FPGA is partially broken. Two power pins are shorted to ground. I unsoldered them. Question: if I replace the chip with a new one, do I need to flash it according to JTAG after soldering?
Sorry for the noob questions.
