| Accuracy | 12bit |
| Sampling buffer depth | 1024 bytes |
| Simulated band width | 0 - 200khz |
| Vertical sensitivity | 10mV/Div - 5V/Div (progressive as 1-2-5) |
| Input impedance | 1 m Ω |
| Maximum input voltage | 50Vpp (1:1 probe) , 400Vpp (10:1 probe) |
| Coupling includes | DC/AC/GND |
| Horizontal time base range | 10 s/Div -- 50 s/Div (progressive as 1-2-5) |
| Vertical displacement is adjustable and indicated | |
| With automatic, regular and single trigger mode, it is convenient to capture instantaneous waveform | |
| Can be triggered by rising or falling edges | |
| Trigger level position adjustable with indication | |
| Observed waveform before triggering (negative delay) | |
| Ready to freeze waveeform display (HOLD function) | |
| It is equipped with 1KHz/3.3V square wave test signal source | |
| Digital display with waveform parameters: frequency, period, pulse, width, duty, ratio, maximum, minimun, average, peak and peak value, effective value. | |
| Save/call out the waveform, the shutdown waveform does not disappear | |
Operation Mode :
- The method of opening/closing waveform parameters display: put the cursor at the time base position, and long press the [OK] key.
- Save waveform method: press [SEL] and [+] at the same time.
- The method of calling out saved waveform: press [SEL] and [-] at the same time.
- Method to enter the test mode: press [OK] and press [RESET] button. If you see the LED flash quickly, it means that the PB or PC port of the single-chip computer (these ports contain the connection with the LCD) has a short circuit, which needs to be found and removed.If you see an LED flashing in a period of about 4 seconds, you can use a voltmeter to find possible openings in the connection lines related to the MCU port. Please refer to the instructions for details
Speciality :
- Reduced the noise of the oscilloscope itself.
- Added waveform save function, the waveform is not lost after shutdown.
- The function of detecting short circuit and open circuit is added, which can help the assembler find welding errors and improve the success rate of assembly.
- TFT controller recognition function is added.
