Dual Channel Tablet Touchable Oscilloscope
Features
- 2-Channel Oscilloscope Multimeter: Upgraded from 2C23T. The 2C53P oscilloscope has 250 MS/s sampling rate, 50 MHz bandwidth. Multimeter 19999 counts, 5 measuring values, max and min display. 4.3-inch IPS touch screen, 480*272 high resolution.
- DDS Signal Generator: Outputs 12 waveforms with a maximum frequency of 10 MHz. The FPGA+MCU+ADC architecture ensures strong waveform capture and supports waveform saving, viewing, and export for analysis.
- Efficiency Improvement: Features one-key AUTO for quick measurements and simplified operations, with automatic/normal/single trigger modes. Suitable for both periodic analog and non-periodic digital signals.
- Comprehensive Analysis: X-Y mode compares phase, amplitude, and frequency of two signals, while FFT spectrum analysis estimates harmonic content and manages complex signals.
- Long Battery Life: Built-in 4000mAh battery provides up to 4 hours of use, with Type-C charging for uninterrupted work.

Amazing mat!
Love it! The texture is nice and smooth, and it didn't take much fighting to get it to lay flat. I appreciate the double-sided nature with a different color on either side-- I end up using the white side more because it helps me see the colors of the polish against the nail better. I recommend making sure the holes on the strap are open before using it just to save yourself the time of fighting with the snap to push it through.

True to color and seems like good quality but even after a week the corners still won’t lay flat

Durable product
Great mat for desk or table for girls that love doing their own nails, or just to use to keep an area clean for a project. Can be rolled up and easily transported. Can switch sides as well! Great product and easy to clean.
