Pickleball noise is comprised of several interactions, one being the paddle impacting the ball and another being people cheering and shouting. The paddle impact noise is one of the issues the industry has faced, and some paddle manufacturers are claiming quiet noise characteristics of their paddles.
In this opportunity, we used the Crystal Instrument’s CoCo-80X to characterize the noise from several paddles for acoustic comparison. The equipment consisted of three (3) microphones mounted on an arch boom and seven specimens to be tested (including different paddles). The testing was done inside the MD Acoustics, LLC’s anechoic chamber at the facilities in Gilbert, AZ.
Read moreAcoustic Consultants are often tasked with analyzing the noise absorption in rooms, studio garages, and storage spaces. The primary challenge in this type of analysis is to find a dynamic signal analyzer with portability, high sampling rate functionality, and complex analysis.

Each application requires a thorough investigation to ensure user safety and comfort. Crystal Instruments is proud to provide the four channel Spider-20E dynamic signal analyzer for Roam to perform acoustic testing on their products.
Read moreNASA’s response to Crystal Instruments addressed items NASA found beneficial, items NASA wanted changed, and items NASA benchmark tested on the prototype units. The Crystal Instruments prototype GRS systems were delivered according to a contractual agreement and performed well when tested for each listed specification with some areas of improvement.
Read moreAerospace hardware (i.e., space crafts) require high intensity acoustic level testing, which is usually accomplished inside a RATF (reverberant acoustic test facility). The acoustic noise level inside the RATF at NASA Plum Brook test station can reach 163 dB, which is the highest level among all RATFs around the world.
Read moreCrystal Instruments is excited to announce the release of EDM 10.0, the latest software version for all Spider and CoCo products serving advanced and fundamental industries in addition to furthering academic advancements.
Read moreTotal Harmonic Distortion (THD) is a critical specification for signal analyzers and electronic components. This application note will provide a description of harmonics and harmonic distortion that is both brief and comprehensive.
Read moreSpectral flatness is a way to quantify the deviation of a passband from being perfectly flat across the frequency spectrum. Like most specifications, the behavior of signals measured in the passband is not ideal and we want to quantify the deviation from the ideal case.
Read moreA manufacturer of laptop fans was suffering from the results of slow production testing. The testing capacity was limited by testing products with manually operating instruments in a quiet room. Crystal Instruments provided the easy-to-use Spider hardware and EDM software package as a solution to significantly improve their production testing.
Read moreFounded in 1996, Crystal Instruments designs and manufactures instrumentation products for machine vibration monitoring, dynamic measurement, and environmental testing. The products are developed in Silicon Valley and our modern lab in North Carolina. Crystal Instruments products are thoroughly tested on a variety of vibration shakers and environmental chambers in our lab during the design phase to meet the extreme requirements of military and aerospace applications.
Read moreThere are two steps for converting an analog signal into a digital signal – quantization in time (sampling) and quantization of amplitude. Any signal that goes through the sampling process is subject to the effect of aliasing. The common use of the word ‘alias’ is used to describe a false name or identity, which is similar to how the term is used in signal processing.

Read moreParadise Fireworks, the only black-powder fireworks manufacturer in Canada, recently rented a Spider-20E signal analyzer for some very unique tests. As a licensed explosion testing site in Canada, Paradise Fireworks was called upon to do some important blast testing for natural gas lines that lie beneath the small structures generally found in residential backyards. The goal of these tests was to define and quantify the dangers associated with having small structures (such as hot tubs and sheds) positioned above the junctions in these gas lines. To do this, Paradise would take pressure measurements from each blast using our high precision Spider-20E signal analyzer hardware in conjunction with our EDM DSA software.
Read moreFeaturing the highest sampling rate provided in the industry at 256 kHz. Handheld battery powered system with wired & wireless network options and 20V input range. Sync between multiple devices. Choose the convenient portable model or industrial model for permanent mounting.
The Spider-20H, Spider-20HE, and Spider-20i received a hardware upgrade to support an impressive 256 kHz samping rate on all 4 input channels. It is the highest sampling rate offered in the market of compact analyzers. The high sampling rate is especially beneficial for measuring high orders and transient capture in blast tests, pyroshock events, drop shock tests, crash tests, etc.
In addition to the high samping rate, the input range is expanded to 20V to capture larger signals.
Read moreCrystal Instruments EDM 9.0 release introduces new additions to the Spider product line featuring support for sampling rates up to 256 kHz.
The new Spider-80Hi and Spider-80Ci are scalable versions of the Spider system featuring the impressive new 256 kHz sampling rate. Recording can also be performed at sampling rates up to 256 kHz for all input channels, up to 512 channels per Spider system.
The compact, ultra-portable four channel version of the Spider has also been developed to support a 256 kHz sampling rate. Currently, three variations of the compact Spiders supporting the 256 kHz sampling rate are available: Spider-20H, Spider-20HE, Spider-20i.

Read moreToday’s engineering tools are the result of constant software development, but these developments aren’t always best for the end-user. Engineers who are heavily invested in their tools will be reluctant to switch to a new device. In a time where software is constantly changing, people don’t have the time to struggle with new software interfaces. Especially field technicians, whose job is to collect and analyze data, don’t like wasting time getting used to a new software interface. Their job is already complicated, and is only made worse with a complicated measurement device. If their tools are too complicated to use, engineers will look for a simpler solution.
