Applications

Electronic products can emit unwanted electromagnetic radiation, or electromagnetic interference (EMI). Regulatory agencies create standards that define the allowable limits of EMI over specific frequency ranges. Testing designs and products for compliance to these standards can be difficult and expensive, but there are tools and techniques that can help to minimise the cost of testing and help to enable designs...

Scanning electron microscopy (SEM) has become a powerful and versatile tool for material characterisation. This is especially so in recent years, due to the continuous shrinking of the dimension of materials used in various applications.  What is SEM? SEM stands for scanning electron microscope. As the name suggests, electron microscopes use electrons for imaging, in a similar way that light...

New FlexRes® oscilloscopes deliver flexible resolution, deep capture memory and mixed signal capability in a USB 3.0 PC connected instrument. Pico Technology, market leader in PC oscilloscopes and data loggers, today introduced the PicoScope 5000D Series FlexRes oscilloscopes and MSOs that feature up to 16 bits of vertical resolution with up to 200 MHz bandwidth and 1 GS/s sampling speed...

Thomas Horseman, Mehdi Tajvidi , Cherif I. K. Diop , Douglas J. Gardner   Lignocellulose nanofibrils (LCNF) were produced from thermo-mechanical pulp (TMP) using a micro-grinder and were characterised with respect to fibre diameter and thermal stability. The initial water content in the TMP affected the defibrillation process and longer grinding time was necessary for the airdried TMP, resulting in...

The BGA244 Binary Gas Analyser, a winner of the 2016 R&D 100 award, can measure the ratio of two gases in a binary mixture or the purity of a single gas. It contains a comprehensive database of nearly 500 different gases allowing measurements on more than 50,000 different mixtures. Measurement accuracy depends on the gas species being measured, but is typically better than...

From Stanford Research Systems (SRS), the recently launched FS740 Time and Frequency system is much more than just a 10MHz frequency reference.  With powerful capabilities and eye-catching performance it is a highly cost effective and multi-functional lab tool. The SRS FS740’s GPS disciplined 10MHz reference delivers caesium equivalent stability and phase noise, but for a fraction of the cost. A...

Never Miss a Signal Today’s RF designs utilise rapidly changing and pulsing signals that are difficult to consistently capture on traditional swept spectrum analysers. The Rigol RSA5000 delivers a class leading 7.45µsec 100% probability of intercept meaning that any pulse with a duration of greater than 7.45µsec will be captured and accurately displayed. Isolate & Capture IoT Device proliferation means...

The Ultra High Resolution OSA (UHR-OSA) proposed by APEX Technologies remains a very important tool not only to measure the optical OFDM (Orthogonal Frequency Division Multiplexing) signal spectrums even with few tens of MHz spacing sub-carriers but also to adjust and adapt it to other modulation techniques. APEX-UHR-OSA incessant need in OFDM research area APEX UHR-OSAs have found a wide industrial and...

The APEX Technologies Ultra High Resolution Optical Spectrum Analyser (OSA) can be used to measure the active/passive optical component insertion loss/gain thanks to the possibility to synchronise the internal Tunable Laser Source and the OSA sweepings. In this context, the APEX OSA remains a perfect tool to measure the Fibre Bragg Grating (FBG) Sensor reflection with 1 MHz of resolution...

For 30+ years Lambda Photometrics have represented Stanford Research Systems (SRS) in the UK as SRS’s authorised UK distributor and service centre with unparalleled experience of supporting their products. To ensure best value for money some companies require several quotes to satisfy their organisation’s purchasing policy. In order to clarify any confusion over comparisons between Lambda’s pricing and SRS’s International...
