Exploring laser frequency stabilization and laser locking techniques
The laser is one of the most important inventions of the 20th century, as far as experimental physics is concerned. Since the first demonstration of a laser in 1960, they have become ubiquitous in research labs across the world, forming a cornerstone of modern optics and quantum research. Laser stabilization, also known as laser locking,…

MEMs characterization 101: Everything you need to know
Everywhere you look, it’s obvious: Devices today are getting smaller. What you may not realize is how small they’re truly becoming. Enter microelectromechanical systems (MEMS). MEMS are tiny devices or systems with both electrical and mechanical components. These systems range from a few micrometers to a few millimeters in size. At these scales, there is…

Search and destroy: Preparing Bloodsport for combat with Moku:Go
Introduction Bloodsport is a heavyweight combat robot designed for equal parts destruction and entertainment. The fierce robot, a competitor on season seven of the Discovery Channel’s popular show BattleBots, has a 46 in (117 cm) spinning arm designed to inflict maximum damage to rival robots. Bloodsport (Figure 1) weighs in at a whopping 250 lb…

Reducing noise and transients with custom real-time digital filtering
In this application note, we utilize Moku Cloud Compile and Multi-instrument Mode to explain the development of a commonly used moving average filter. We use both the Oscilloscope and Frequency Response Analyzer to examine this basic finite impulse response (FIR) filter. Then we develop, deploy, and examine a five-point median filter using Moku:Pro, Moku:Lab, or…

Sampling Theorem
Signal digitization is an essential step to enable digital signal processing (DSP). It converts an analog signal to discrete-time binary numbers and allows the signal to be processed with digital logic devices, such as CPUs, application-specific integrated circuits (ASIC), and field-programmable gate arrays (FPGA). To ensure the conversion process retains the maximum signal fidelity, the…
