Additive phase noise refers to the phase noise introduced by subsystems or specific components within a signal chain, characterizing devices or systems that signals pass through (e.g., mixers, #amplifiers, and other multi-port signal processing devices) rather than those that generate a waveform natively. So, how do you properly configure your test setup to measure the additive phase noise of a device under test (DUT)? Uncover the answer in our latest blog post. https://hubs.la/Q02LrqZX0 #TestAndMeasurement #PhaseNoise #AdditivePhaseNoise

The definition and working principle of programmable optical attenuator Programmable optical attenuator, as the name suggests, is a device that can accurately adjust the intensity of optical signals through program control. It uses advanced electronic technology and precise optical design to achieve flexible control of optical signal intensity by changing the loss in the light transmission path. This process usually involves the synergy of interference effects and program-controlled units to ensure stable transmission and precise control of optical signals in optical fiber communication systems.

Understanding Vacuum PMT vs. Silicon PMT: Key Differences and Insights When it comes to photodetectors, Vacuum Photomultiplier Tubes (PMTs) and Silicon Photomultipliers (SiPMs) each have distinct characteristics that cater to different applications. Here’s a concise breakdown for professionals in the field: Working Principle: 1️⃣ Vacuum PMT: Utilizes a vacuum tube where photons strike a photocathode, releasing electrons that are multiplied through a series of dynodes. 2️⃣ Silicon PMT (SiPM): Composed of an array of avalanche photodiodes operating in Geiger mode, where incident photons trigger electron avalanches within a silicon matrix. Advantages: 1️⃣ Vacuum PMT: Offers high sensitivity and large active areas, excelling in applications requiring ultra-low light detection. 2️⃣ SiPM: More compact, robust, and capable of operating at lower voltages with higher photon detection efficiency (PDE). Immune to magnetic fields and ideal for environments where space and resilience are crucial. Conclusion: Vacuum PMTs remain the gold standard for ultra-sensitive, low-light applications, while SiPMs are gaining ground in modern detection systems due to their compact design and versatility. The choice depends on the specific application’s requirements in terms of sensitivity, space, and operating conditions. #BertholdTechnologies #WehayaProcess #RadiometricTech #PhotonDetection #PMTvsSiPM #IndustryInsights #Expert

Charged particle microscopes are frequently tasked with imaging and manipulating smaller specimens than ever before, particularly to support the development of 10-nanometer nodes and finer semiconductor devices. In order to achieve this resolution, precise control of precursor chemicals and charge compensator fluids is required. Due to harsh application environments, these high-technology instruments require robust components capable of operating within a vacuum and at elevated temperatures. The Lee Company's IEP Series solenoid valve precisely controls critical fluids in adverse environments and is uniquely suited for multiple charged particle microscope applications. https://thelee.co/3TsZlI3

Here's a nice Vero AFM example of single frequency piezoresponse force microscopy (PFM) on Aluminum Nitride that Asylum Research's Ted Limpoco just posted. Why?? This AlN sf PFM example is so clean & detailed considering how tiny the amplitude signal change is: A tight 180 phase shift in vertical domains as the should (< left red /blue ), and a tiny sub 10pm envelope in the PFM amplitude channel (>right yellow/brown ). Really nice resolution in both PFM channels. Also notice the consistent mirrored tracking between trace & retrace oscilloscope lines too. I've watched this video about 10 times in a row- it's hard to look away because it's so nice AND it's only a 10pm displacement with an AFM tip. Wow! The Vero interferometric AFM is yet another example of commercial AFM design innovation leadership from the staff at Asylum Research. Thanks for sharing Ted!

Cadmium telluride (CdTe) crystals in the new QuantaMax detector allow direct conversion of X-rays into an electrical signal rather than light. This CdTe semiconductor crystal differs from standard scintillation detector, as it enables individual measurement of each X-ray photon in a single projection. QuantaMax detectors create CT images at high spatial resolution, without electronic noise, and with an improved contrast‐to‐noise ratio, intrinsic spectral information, and at a lower radiation dose. Combining the above capabilities with Dual Source temporal resolution enables visualization of fine details for increased diagnostic confidence. https://lnkd.in/d4QcfGdd #SiemensHealthineers #QuantaMaxDetector #PhotonCounting #QuantumTechnology #NaeotomAlpha
