Exceptional Performance and Outstanding Customer Service
I recently purchased the FNIRSI 2C23T 3 in 1 Handheld Oscilloscope Multimeter DDS Generator and I must say, it has exceeded all my expectations. This versatile tool, with its 2 channels and 10MHz bandwidth, coupled with a 50MSa/s sampling rate, has made my electrical measurements and diagnostics tasks remarkably efficient and accurate. The 10000 count multimeter functionality is a bonus, seamlessly integrating voltage, current, capacitor, resistor, and diode testing capabilities into one compact device. But what truly sets this product apart is the outstanding customer service I experienced. Upon realizing that an oscilloscope probe was missing from my package, I contacted their support team. Not only did they respond promptly and courteously, but they also exceeded my expectations by immediately sending the missing probe. To my surprise and delight, they included a free tiny oscilloscope as a goodwill gesture. This level of customer care is rare and truly appreciated. The device itself is user-friendly, robust, and reliable, making it an essential tool for professionals and hobbyists alike. Its intuitive interface and crisp display add to the overall user experience. The accuracy and range of measurements it offers are comparable to more expensive models in the market, making it a cost-effective solution for a wide range of electrical testing needs. In conclusion, the FNIRSI 2C23T is not just a high-quality product, but it's backed by a company that genuinely cares about its customers. Their prompt and generous response to my issue has earned them a loyal customer. I highly recommend this product to anyone in need of a reliable and versatile electrical testing tool. Five stars well-deserved!

It does what it says it will
The little o'scope that CAN. Works great for audio and HF radio frequencies (up to10 Mhz). Loved that it came with two 100 MHz probes with hooks that compensate well. The probes can be color-coded for easy identification when using both oscilloscope channels. The signal generator, accessible from the main menu, can be used simultaneously with any other instrument (oscilloscope or multimeter). The signal output defaults to 3.0 volts peak-to-peak and can be adjusted up to 3.3 volts peak-to-peak. Common waveforms are available, including Sine, Square, and DC. The frequency counter on the oscilloscope works well, although it changes from 799 Hz to 0.80KHz, which is a little visually distracting and not great if you're looking for exactly 800 Hz (which I was) since a digit of accuracy is lost at the switching point. I'd prefer that it switch at 1 KHz, but it's hard to complain for the price. It's also missing a calibration output for easy probe compensation checks, but use the signal generator to send a square wave at the frequency you intend to work near, connect the oscilloscope probe(s) to the included test leads, and the probe compensation is easily adjusted. The multimeter performs common tasks needed with modern Digital Multi-Meters, including auto-ranging Voltage, Resistance. and Capacitance tests. I haven't used it to measure current, but I probably won't ever do that anyway - I prefer to test current with a dedicated current meter to avoid mistakes and letting out the magic smoke. I ran the oscilloscope for several hours and barely moved the battery indicator icon on the screen. The battery quickly charged on a USB-C charger (not included, but a USB-C to USB-A cable is included) and will charge while it is being used. It's an excellent product for the price, in my opinion. Well done!

Useful all-in-one tool
This handheld oscilloscope and multimeter combo works great for most tasks. The screen is clear, and it tests voltage, current, and components well. The DDS generator is a nice extra. The only downside is the controls aren’t super intuitive, and the manual could be better. Overall, a solid, versatile tool if you don’t mind spending some time figuring it out

Diagnostic Bench in your hand
Little guy gets it done. Replaces a bench 'scope and signal generator for most practical applications. High enough voltage rating to work with most of my tube circuits. Great for when you need to see digital data. Does good job showing noise, voltage drops, and signal overshoot. Much better user interface than older generation units. Very intuitive and almost no need for manuals. I love the ability to simultaneously generate a signal and then monitor it else where on a circuit.

I’m very impressed with the functionality and the quality of this little unit, the telescope is very clear and easy to read. Easy to change settings and works well. Highly recommend this I do demonstrations in the automotive world and I’m utilizing this as telescope also diagnose many hard to find problems on a Land Rover with the same scope highly recommend

Good with dso153

great screen, nice and sharp. scope is adequate for quick signal captures up to 15meg(12meg stable). does not have all the math functions of a full size scope... no XY. but again... good for quick captures. multi meter is surprisingly good. weakest part is the function generator. having said that if you just need a quick signal to pump into a circuit like an audio amp its just fine. don't count on this being your main scope but again... it works for quick and dirties. easily as good as scopes costing a lot more
