must be like an universal programmer, switching and level shifters if there is any ?? |

I just received a DSO-TC3 today. I'm looking forward to playing with this new toy. |

Any clues on what MCU is actually used? We are looking for LQFP-100, at least 512k FLASH (the firmware update file is roughly 360k), USB and at least one fast ADC and a DAC. Most likely an ARM Cortex or maybe much less likely a RISC V. Today I stumbled across a Chinese company I never heard about before (https://www.nationstech.com/). Their products are available at LCSC. Line card (https://www.nationstech.com/uploadfile/file/20220407/1649311413763814.pdf) N32G452VEL7 (2x ADC, no OPAMP) N32G455VEL7 (4x ADC, 4x OPAMP) N32G457VEL7 (4x ADC, 4x OPAMP, Ethernet) My guess would be on that one : N32G455VEL7 datasheet: (https://www.nationstech.com/uploadfile/file/20220906/1662453066413965.pdf) manual: (https://www.nationstech.com/uploadfile/file/20220906/1662453133922816.pdf) |

I bought the TC3 because I liked the TC1 transistor tester, and thought the extra toys were cute. Definitely a toy though. I connected it to my scope and dmm, and the TC3 RMS is typically ~0.5V low. Sometimes only 30mV off, but usually closer to the .5V. What I find goofy is the displayed values and the waveform don't make sense unless they're displaying it upside down. 🤷 The source is the AWG on the SDS2X04XP. 4Vpp set, 1kHz. |
