Global Oscilloscopes & Probes Suppliers & Exporters

For digital square waveforms, system bandwidth must not be selected based solely on fundamental clock frequency. Instead, base it on the 10%-90% signal rise time (Tr). According to the classic relationship: Bandwidth (f-3dB) = 0.35 / Tr for single-pole Gaussian responses (or 0.45 / Tr for modern high-order flat-response digital oscilloscopes). To preserve signal integrity with less than 3% measurement error, the combined oscilloscope and probe system bandwidth must be at least 3x to 5x higher than the highest frequency harmonic present in the edge transition.

While passive probes exhibit high resistance (typically 10 MΩ) at DC, their tip capacitance (10 pF to 15 pF) acts as a low-impedance shunt at high frequencies. At 500 MHz, a 12 pF probe has a reactance of only ~26.5 Ω, drastically loading the Device Under Test (DUT), causing false edge ringing, slowing rise times, or causing circuit malfunctions. Active FET probes feature ultra-low tip capacitance (<0.5 pF to 1 pF) and multi-gigahertz input impedance, preserving true circuit dynamics.

An 8-bit analog-to-digital converter divides the vertical voltage scale into 256 quantization levels (2^8). In contrast, a true 12-bit ADC provides 4,096 discrete levels (2^12)—a 16x increase in vertical resolution. This gives engineers the ability to zoom into small dynamic perturbations (such as millivolt-level clock jitter or power rail ripples) while simultaneously displaying full-scale 5V or 10V switching waveforms without frontend overload or clipping.

Yes. All brand-new equipment supplied by Machine-Win Technology originates from verified OEM industrial channels with original factory serial labels, standard accessory packages, factory calibration paperwork, and standard manufacturer warranty protection. In addition, Machine-Win provides secondary engineering warranty coordination and calibration support through our Hong Kong and Shenzhen test labs.

All outbound instruments are packaged using multi-layer high-density anti-static foam, impact-resistant corner reinforcements, and moisture barrier sealed vacuum bags, encased in custom heavy-duty triple-wall corrugated outer cartons or certified road-ready flight cases. Sensitive precision oscilloscopes include tri-axial tilt and drop shock indicators to ensure transit accountability via international air carriers (DHL/FedEx/UPS/Air Cargo).

Yes. When submitting RFQs, buyers can specify complete model numbers along with required hardware option boards (e.g., arbitrary waveform generators, logic analyzer channels) and software application packages (such as jitter analysis, power integrity, DDR compliance, or automotive serial bus decoding). We coordinate full factory licensing registration before order finalization and shipping.
