content: Dear All,I recently purchased the FNIRSI 2C53T and have been testing the device. While experimenting with low frequencies, I noticed that the device fails to detect low-frequency patterns when using the auto button. Suspecting this might be a software issue, I checked for the latest firmware updates for the 2C53T.After some research, I found the following link:FNIRSI Support and DownloadsI downloaded the 2C53P Firmware_V1.8.zip file, which contained the following:APP_2C53P_V1.8_240611FPGA_2C53P_V1.6_20240527I attempted to upload these files by pressing Menu and Power simultaneously. Unfortunately, this left the device stuck in a perpetual upgrade loop. I tried using a needle to reset and restart the device, but the issue persists. I now suspect these files may be intended for the touchscreen model, not the 2C53T.FNIRSI's website could benefit from clearer documentation. I also came across firmware files for the 2C32T, but their file structure appears different.I would greatly appreciate any guidance on how to bypass this update issue and restore normal functionality to the device.Thank you in advance for your assistance.Best regards,

content: Dear Gentlements,I have received the following message from FNIRSI. They responded fairly rapidly. I recovered the device and will perform additional tests on it. I am sharing for anyone who has similar problems.Have a good day,Dear Customer,Thank you for supporting our products! Please note that 2C53T and 2C53P are three different devices, and their firmware is not compatible with each other. Installing firmware designed for another model may cause program errors and disrupt the normal functionality of your device.Here is the factory firmware for 2C53T for your reference and download:https://www.mediafire.com/file/124kejdy7wo5s19/APP_2C53T_V1.0.3_240814.bin/fileIf you need further assistance or have any questions, please feel free to contact us. We are always here to help!Best regards,FNIRSI

content: I hope this message finds you well. Unfortunately, I’ve decided to return the 2C53T products for the following reasons:The oscilloscope function did not perform as expected.My primary requirement was accurate multimeter measurements, which were not satisfactory.Due to budget constraints, I opted for the UNI-T UT181A instead of a Fluke multimeter, which is often considered the gold standard.Outcomes of My Decision:After switching to the UNI-T UT181A, I immediately tested my Prolink DC power supply. The results confirmed minimal deviation, contrary to the 5% error reported by the Mastech MY68 multimeter. This misreading previously led to an unnecessary $600 expense (Turkey import Taxes High) on a RIGOL DC power supply.Moving forward, I will rely on the RIGOL MSO5000 for oscilloscope functions and avoid purchasing overly versatile multimeters, as they often compromise accuracy.Key Takeaway:As the saying goes, “If you cannot measure accurately, you cannot manage effectively.”Thank you for your understanding. I hope my experience helps others make informed decisions.

content: So what did the scope not do that you expected ? And how bad was the DMM part ?I'm thinking of getting one of these, or something with similar price/performance, just as a basic field DSO. I think there's better performing mini-DSO's, but it would be nice to have the DMM and AWG all in one, and portable. I'm not sure if I'd the tablet version, or the more handheld version.Considering the 12-bit SDS804X HD is near $400USD for me, I don't want to spend near $250 on something like the OWON 200MHz 2202.Now I already have an accurate 5.5D handheld DMM, but in the couple of video's I've seen of these FNIRSI's, they seemed about right.Now I won't be trying to measure the current of a clothes dryer, or looking for the high voltage peaks on some SMPS.

content: Quote from: MathWizard on January 13, 2025, 02:57:50 pmThe two Fnirsi are equally garbage.The specifications do not reflect reality.My experience is only with the 2C53P, which is real garbage.Based on the videos I watched, the 2C53T is no better.Fnirsi is lying about its product spec, the memory and samplerate look like less.What you wrote about the Owon HDS2202 is a bit outside this category, because it really has a sampling rate of 1GSa/s / channel!, while these two Fniris do not even come close to 250MSa/s.Comparing the 2C53P that I have with my Owon HDS272s, I have to say that the Fnirsi is not 250MSa/s and the memory is not 64k as it says.The two below could be in a similar category with the two Fnrisi.In terms of price-performance ratio, the Owon HDS242s or the DSO3D12 are better.But the control of the Owon is unusual for many people. they don't like it.The DSO has been recommended several times by others.
