Features and benefits

Why I love FNIRSI 1013D

• Dual-Channel Input with 100MHz Bandwidth and 1GSa/s Sampling Rate
  The FNIRSI-1013D oscilloscope features two input channels, each with an analog bandwidth of 100MHz and an impressive real-time sampling rate of 1GSa/s. This allows users to simultaneously measure and compare two different signal groups, which is critical for analyzing tasks such as comparing amplifier input and output signals to assess gain and distortion, or testing complementary PWM signals in half-bridge/full-bridge switching power supplies. The 1M ohm input impedance ensures minimal impact on the circuit under test.
• Intelligent Anti-Burn Protection up to 400V
  Both input channels incorporate built-in high-voltage protection modules, capable of withstanding continuous input voltages of up to 400V. This feature significantly reduces the risk of accidental oscilloscope damage if the user forgets to switch the probe to the 10X position when measuring high voltages, ensuring device longevity and safety.
• Full-Featured 7-inch Capacitive Touch TFT Display
  The device is equipped with a 7-inch color TFT LCD display with an 800*480 resolution, providing bright colors and high contrast. The capacitive touch operation, similar to modern smartphones and tablets, makes interaction with the instrument extremely convenient and intuitive, eliminating the need for outdated resistive touchscreens.
• One-Button Automatic Adjustment Function
  The FNIRSI-1013D eliminates the need for tedious manual adjustments thanks to its highly efficient fuzzy control algorithm, which ensures high accuracy. In just 1 second, the oscilloscope can automatically adjust a 1V peak-to-peak signal, significantly faster than typical desktop oscilloscopes, which take about 5 seconds. The adjusted waveform is always displayed in the center of the screen, simplifying quick analysis.
• Comprehensive Trigger Functions and Roll Mode
  The oscilloscope offers three trigger modes: automatic, single, and normal. The single mode is ideal for testing sudden, non-periodic burst signals, such as car ignition signals. The normal mode is designed for non-periodic digital logic signals, like infrared remote control signals. The automatic mode is used for periodic analog signals, such as sinusoidal waves. Additionally, the large time base scroll mode allows for monitoring slow level changes, expanding the device’s versatility.
• Built-in Storage and Waveform Manager
  With 1GB of built-in storage, the FNIRSI-1013D can store up to 1000 screenshots and 1000 sets of waveform data. The saving process is simple and fast, allowing users to save the current waveform with a single touch at any time. The powerful waveform image manager supports thumbnail browsing, detailed viewing, page turning, deletion, as well as zooming in, zooming out, and moving waveforms for convenient secondary analysis. The presence of a USB interface allows for easy transfer of screenshots to a computer.
• Long Battery Life and Advanced Analysis Features
  The built-in high-quality 6000mAh rechargeable polymer lithium-ion battery provides up to 4 hours of continuous use after 5 hours of charging, with the ability to operate while charging. In addition to basic functions, the oscilloscope supports Lissajous figure display for determining the amplitude, frequency, and phase contrast of two signal groups, as well as a harmonic component analysis function, making it a powerful tool for in-depth diagnostics.

Pros and Cons

Strengths & Weaknesses:

What I Like
— Dual-channel input with 100MHz bandwidth and 1GSa/s sampling rate for comprehensive analysis.
— Intelligent anti-burn protection up to 400V, enhancing safety and durability.
— 7-inch capacitive touch TFT display with 800*480 resolution for intuitive control.
— One-button automatic adjustment function, significantly speeding up the measurement process.
— Built-in 1GB memory for storing 1000 screenshots and 1000 waveforms, with a convenient manager.
— Long battery life (4 hours) thanks to the 6000mAh battery.
— Support for Lissajous figures and harmonic analysis for advanced diagnostics.
— Versatile trigger modes (automatic, single, normal) and scroll mode.

Points to Consider
— Lack of a carrying case in the package (according to user reviews).
— Glossy screen, which can create glare and hinder viewing at an angle.
— The stand handle might be flimsy and detach.
— Limited menu functionality compared to some analogs (e.g., no 20 MHz bandwidth selection or inactivity timeout).
— Issues with cursor placement and waveform scrolling at low frequencies (1 Hz and below).

• ⭐ 5.0/5 | Yo: This is a very good product!
• ⭐ 1.0/5 | AliExpress Shopper: This isn’t worth $50 I may send it back. it’s voltages are way off. The frequency is off sometimes. The interface is terrible. I would not recommend this.,the voltages are off with both scopes at 10x and 1x. I only sent the 10x picture. can’t use this for anything precise. All your data will be off. this is only at 40hz so not real high frequency. if it’s off this much al low frequency it will be worse at high frequency. it’s a TOY Oscilloscope. not good for any real work
• ⭐ 5.0/5 | Jo: Everything is fine, no issues, thanks
• ⭐ 5.0/5 | lo: Reliable seller, the package arrived right on time
• ⭐ 5.0/5 | Шч: Fast shipping and secure packaging. The kit includes two chargers. On the downside, there is no storage case included. The device is fully functional. Thanks to the seller!
• ⭐ 5.0/5 | Mh: Seems to work well. Wish it came with a protective case though.
• ⭐ 5.0/5 | Ич: Everything is great, received it. Delivery was very prompt.
• ⭐ 5.0/5 | AliExpress Shopper: Everything is perfect.

• ⭐ 5.0/5 | Lh: Everything works great. Complete set, thank you Fnirsi.
• ⭐ 5.0/5 | AliExpress Shopper: Everything is super
• ⭐ 4.0/5 | Я: The screen is quite large compared to alternatives, but the display quality is poor—viewing angles are terrible, you can’t see anything if tilted. The kickstand handle is loose and keeps popping off, which is frustrating; it detached the very first time I grabbed it. It desperately needs a proper locking mechanism. The firmware features are minimal; they definitely could have optimized the interface. Otherwise, the build hardware is decent. Overall, it serves its purpose. P.S. Bought it specifically for automotive diagnostics.
• ⭐ 5.0/5 | Зч: Delivered in just 4 days, came as a full kit including the 100x probe. All this for just over 8k rubles. For this price, it is an absolute steal! All its quirks are well-documented online, so buyers know exactly what they are getting. I was slightly surprised by the extreme simplicity of the menu (e.g., no 20 MHz bandwidth limit option or auto-power-off timer), making it more basic than the 2C53P, but this one definitely runs smoother. The seller is great, responds quickly and adequately to messages. Not my first time buying from them. No point uploading photos, looks just like everyone else’s.
• ⭐ 5.0/5 | ма: Delivered in 6 days. Everything is top-notch.
• ⭐ 4.0/5 | Вч: Shipping was delayed, had some issues picking it up from the automated parcel terminal.
• ⭐ 5.0/5 | Sv: Arrived 5 days ahead of schedule. Excellent packing job. The tool is fully operational. Haven’t fully tested it in deep field work yet, but I really like it so far.
• ⭐ 5.0/5 | кч: Excellent
• ⭐ 5.0/5 | Sh: Great scope for automotive electronics. The seller is highly responsive and helpful with questions. Received a high-voltage probe as a bonus. Everything operates perfectly for now. Thanks to both the developers and the seller!
• ⭐ 5.0/5 | Ah: Great device, arrived rapidly and intact. Had some initial trouble understanding the manual and verifying if it worked properly, but tech support resolved my questions instantly. Thank you for the quick assistance and a solid product, highly recommended!)
• ⭐ 5.0/5 | Бч: Superb item.
• ⭐ 5.0/5 | Ty: Works as intended. Kudos to the manufacturers for making equipment affordable for regular users. Excellent scope. The seller packed it safely in a massive foam box. Everything is undamaged.
• ⭐ 4.0/5 | Al: Inspected the item. Everything operates properly. Delivered on schedule.
• ⭐ 5.0/5 | Нв: Item matches the description perfectly. Ultra-fast shipping. Definitely recommend this seller.
• ⭐ 5.0/5 | Тч: Neat packaging. The unit is functional. Plus got a 1:100 probe included. Swift shipping.
• ⭐ 5.0/5 | Чч: Solid oscilloscope, best performance you can get for this price point.
• ⭐ 3.0/5 | Кч: The screen is large but has a highly reflective, glossy finish that acts like a mirror, which is very distracting. Battery life is solid. However, when displaying low frequencies around 1 Hz or less, it is impossible to set up cursors, and there is no option to choose the used memory depth. Additionally, waveform scrolling is missing—you cannot zoom into a specific segment in any of the operation modes.
