Conceptually, the interferometer is a relatively simple instrument that compares two distances typically differing only by a slight amount. Two waves, often coherent light waves, reflect from standard mirrors mounted at the object under investigation. The light from one mirror passes through a half-silvered mirror while the light from the other reflects from the back […]
Test and Measurement Tips
RF hybrid couplers optimized for wide-band applications
New RF hybrid couplers meet high-frequency component demands. The high-performance hybrid couplers are candidates for RF applications requiring an equal split of input and output ports with 90° or 180° phase shifts while maintaining high isolation between ports. Fairview’s 21 new RF hybrid coupler models feature a coaxial design with SMA and 2.92-mm connectors. They […]
Scopes provide 10 GHz bandwidth for up to eight channels
The new 6 Series B Mixed Signal Oscilloscope (MSO) extends the performance threshold of the Tektronix Mainstream Oscilloscopes Portfolio to 10 GHz and 50 GS/sec. Developed to meet the demand for high-speed data movement and processing in embedded designs, the enhanced 6 Series B MSO offers leading signal fidelity with12-bit ADCs and extremely low noise, […]
Setup speeds testing of distributed antenna systems
Rohde & Schwarz USA, Inc. has engaged with SkyBridge Services in the U.S. to simplify distributed antenna system (DAS) installation and maintenance. Supported by the SkyBridge cloud-based test management tools, the R&S Cable Rider ZPH is factory calibrated to provide fast, efficient and accurate cable and antenna measurements up to 4 GHz. Operated via a […]
Difference between measuring resistance and conductivity
Generally, an electrical conductor is a long solid rod, often insulated. It may be rectangular, like the electrician’s bus bar, irregular in cross section, or it may be merely a conductive path through the atmosphere, created by a process of ionization. Most electronics professionals have measured the resistance of conductors typically using a volt-ohm meter. […]
Signal/spectrum analyzer hosts 8.3 GHz internal analysis bandwidth
With the new R&S FSW-B8001 option, the well-established R&S FSW high-end signal and spectrum analyzer supports an industry-leading 8.3 GHz internal analysis bandwidth, offering unequaled dynamic range and sensitivity. Design engineers developing latest radar and wireless communications technologies as well as future satellite systems will benefit significantly from the extended bandwidth available in a one-box […]
Versatile development enclosures support SOSA, OpenVPX
Versatile backplane/chassis configurations are geared for 3U and 6U OpenVPX and SOSA development. The versatile development enclosures start with a line of single-slot power and ground backplanes in various 3U and 6U configurations. This includes VITA 65 (standard VPX), VITA 66.4 (VPX with optical), and VITA 67.3 types (VPX with RF). The backplanes can be […]
Four/eight-channels mixed signal scopes come in 350/500-MHz models
New DLM5000 oscilloscopes are successors to the eight-channel DLM4000 series mixed signal oscilloscopes and feature a number of improved functions and enhanced operability. In addition, a DLMsync option is planned to be released by next spring that will enable measurements to be taken simultaneously by two connected DLM5000 oscilloscopes. The DLM5000 series is targeted at […]
Are you sure you know what bandwidth means?
Bandwidth is a principal specification when choosing an oscilloscope or related instrument. What it means in this context is a displayed signal’s maximum frequency above which the scope attenuates the amplitude of the signal it sees. Problem is, this isn’t the only definition of bandwidth. The concept has slightly different meanings (and consequences) depending on […]
Multifunctional 16-bit AWGs include synchronized digital pattern generation
The T3AWG2152 and T3AWG2152-D generators are multifunctional 150MHz arbitrary/sweep/function generators that combine multiple functions in a single instrument, including a two-channel function and arbitrary waveform generator with an eight-channel digital pattern generator (in the D version). These three different functionalities are based on an advanced Direct Digital Synthesis (DDS) technology which allows glitch-free on-the-fly changes […]
