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...

An absolute position measurement system has a noise floor of less than 0.02 nm/√Hz over a range of 1.2 mm. Measuring to the nanometer scale is no small feat—getting there takes careful engineering and a fundamentally good sensor. The sensors used for stage position feedback inside semiconductor lithography tools regularly achieve this level of precision. Zygo has supplied displacement measuring...

Stanford Research Systems BGA244 The BGA244 Binary Gas Analyser from Stanford Research Systems (SRS) is a new product harnessing the fundamental physical principles of acoustic resonance to measure the speed of sound in a gas mixture and provide gas ratio measurements with errors as low as 100ppm. This technique has advantages over conventional thermal conductivity binary gas analysers with...

Mosa creators of award-winning, leading edge, high tech tile for walls, floors and terraces, began barely a year ago to work with SEM, an advanced electron microscopy technology. In that short space of time, however, the device that is the size of an old PC has proved its effectiveness, helping Mosa achieve a significant step in its efforts to research the chemical nature...

Chromatic-dispersion Based on complex spectral analysis of the optical field, the Apex Technologies Optical Complex Spectrum Analyser AP2441B/AP2443B is able to measure the chromatic dispersion and the group delay of a transmission line. This paper is dedicated to explain clearly the measurement method of two examples of a 13.2 km standard Single Mode Fibre (SMF) length using a 10 Gb/s...
