Digital 100 MHz Oscilloscope with 16-Channel Logic Analyzer — 1 GSa/s

At 1 Giga-sample per second, this instrument samples faster than the 100 MHz Nyquist limit with 5× headroom — reconstructing waveforms that would alias into noise on anything slower.

A digital storage oscilloscope converts analogue voltage to digital samples via a flash ADC, stores them in acquisition memory, and renders the waveform on a display. At 100 MHz bandwidth with 1 GSa/s sampling, the Nyquist theorem guarantees faithful reconstruction of waveforms up to 500 MHz. The 16-channel logic analyzer input operates at 100 MSa/s with configurable protocol decoding: I²C, SPI, UART, CAN, LIN, I²S — directly correlating digital bus transactions with analogue waveforms in the same time base. Essential for debugging microcontroller firmware and RF modulation waveforms simultaneously.

• 2-channel analogue: 100 MHz bandwidth, 1 GSa/s, 14 Mpts memory depth
• 16-channel logic analyzer: 100 MSa/s, 25 MHz max; protocol decoding for I²C/SPI/UART/CAN
• 7-inch 800×480 capacitive touchscreen; 9 trigger types including serial bus
• FFT spectrum analysis, waveform math, USB storage, LAN connectivity

Every purchase directly funds independent physics research at the Golden Physics Project.

Expert Analysis

A 100 MHz bandwidth oscilloscope with 1 GSa/s sample rate satisfies the requirements for general electronics diagnostics, embedded systems development, and RF troubleshooting up to VHF frequencies. The Nyquist criterion means you can accurately reconstruct signals up to 500 MHz — sufficient for I2C, SPI, UART, CAN bus, most audio work, and analog signal chains well into the RF range. The 16-channel logic analyzer integrated in the same chassis is the feature that separates this from a single-function scope: simultaneous analog and digital capture lets you correlate a protocol decode with the analog waveform in real time, which is precisely how professional engineers debug embedded systems where digital control and analog behavior interact.

Mixed-signal oscilloscopes at this bandwidth historically cost several thousand dollars from established instrument manufacturers. The price reduction over the past decade reflects largely semiconductor and ADC advances, not fundamental compromises in measurement capability. The 14 Mpts memory depth — 14 million samples stored per acquisition — is the specification that allows capture of long events at full sample rate, which matters when debugging infrequent glitches or slow communication protocols. The 9 trigger types, including serial bus triggering, allow capture of specific protocol events without continuously searching through raw waveform data.

If you are designing or debugging electronic hardware — microcontroller projects, audio amplifiers, power supplies, motor controllers, or RF circuits — an oscilloscope is the single most important instrument in your lab. This one covers the territory where 90% of practical electronics work happens. The touchscreen interface and LAN connectivity mean you can control it remotely and export waveforms for documentation without fiddling with USB drives.
