? 1. Hardware Specifications

✅ Bandwidth – 250 MHz

• Allows accurate measurement of high-frequency signals.

• Ideal for analyzing fast digital pulses, RF signals, switching power supplies, and clock signals.

✅ Sample Rate – 1 GS/s (Giga Samples per Second)

• Captures fast transients and sharp edges in waveforms.

• High sample rate ensures accurate signal reconstruction.

✅ Channels – 4 Analog Channels

• Simultaneously capture and compare up to four different signals.

• Useful for debugging multi-signal systems like microcontrollers, I2C/SPI buses, or motor drivers.

✅ Memory Depth – Up to 64M Samples

• Stores more data for long-duration signal capture at high resolution.

• Important for analyzing slowly changing signals or catching rare glitches.

✅ Vertical Resolution – 8-bit

• Standard resolution for most oscilloscopes — good balance between performance and file size.

• Suitable for most general electronics and debugging work.

✅ Input Impedance – 1 MΩ ±2%

✅ Input Capacitance – 20 pF ±5 pF

• Compatible with standard oscilloscope probes.

• Handles a wide range of voltage levels without introducing signal distortion.

✅ Input Voltage Range – ±40 V (DC + Peak AC)

• Safely measures signals with substantial voltage swing.

• Protection circuits prevent damage from accidental overvoltage within spec.

?️ 2. Trigger & Measurement Capabilities

? Trigger Types

• Edge, Pulse Width, Slope, Video, Alternate

• Sophisticated triggering allows users to isolate and capture only the events of interest.

• For example, trigger on a falling edge that only occurs after a long pulse.

? Auto & Manual Measurements

• Automatically measure voltage (RMS, peak-to-peak), time (frequency, period), and logic properties (rise/fall time, duty cycle).

• Save time and increase accuracy versus manual cursor placement.

? FFT & Math Functions

• Built-in Fast Fourier Transform (FFT) for frequency-domain analysis.

• Add, subtract, multiply signals; useful for advanced diagnostics like power consumption analysis and harmonic distortion.

? 3. Software & PC Integration

? Compatible with Windows (XP – 11)

• Plug-and-play USB connection.

• Install the Hantek software to turn your computer into a full-featured oscilloscope interface.
