With the proliferation of high-speed peripherals in systems design, interface compliance has become a non-negotiable requirement. In particular, the USB 3.0 (SuperSpeed USB) standard demands stringent verification of physical-layer parameters, signal integrity and jitter performance. The RIGOL DS80000 Series oscilloscope, paired with the dedicated USB 3.0 Compliance Test software option, offers a powerful platform for performing full physical-layer compliance testing...

The CS548 isolated-channel oscilloscope can be used for Double Pulse Testing (DPT). This white paper illustrates the measurements that can be made, and how to interpret them. This paper should be read in conjunction with the CS1501 Insertion Inductance white paper, which identified the insertion inductance of the CS1501 1 mΩ current sensor to be 163 pH. Click HERE to...

A jet engine is a marvel of engineering. Its seamless orchestration of components enables takeoff, flight, and landing—events we’ve come to expect with confidence. But behind this reliability lies a world of extreme conditions and uncompromising standards.Jet engines operate at temperatures exceeding 3000°F, and this heat is not just a byproduct but a necessity for fuel efficiency and performance. Advances...

Probe Tips or Probe Needles come in a variety of materials, lengths, shapes and tip diameter or radii (Everbeing are stated in tip diameter). They provide direct electrical contact to the circuit under test. Probe tips are specified to suit each individual application. Considerations should be made regarding the material to be probed, temperature, bond pad size and bond pad...

To make sure high-performance optical systems don’t crack under pressure, selecting the right material is not a secondary consideration, it is foundational. The substrate used for an optical window or mirror governs the system’s optical performance, thermal stability, and resilience under operational conditions. Zygo™, a global leader in precision optics, distinguishes itself through a material-agnostic capability, manufacturing from an exceptionally...

Outline of Optical amplifier measurementWith the increase in communication traffic, the importance of optical amplifiers such as EDFAs (erbium-doped fiber amplifiers) that can directly amplify optical signals without converting them into electrical signals has been widely deployed in traditional backbone optical transmission networks. This proven amplification technique has expanded to a next generation application to boost free space communication laser...

Overview of Pulsed Light Measurement Why use pulsed light? A semiconductor laser emits light by a driving current. This drive current causes the semiconductor laser chip to generate heat, causing a shift in the output wavelength and potentially damaging the laser. To avoid such problems, pulse-driven light emission is widely used. Furthermore, high-power industrial lasers may require an energy accumulation...
