Part 1 of this FAQ introduced some of the basic issues related to the measurement of RF power, which is a primary parameter in most RF designs. Part 2 continues the discussion, looking at RF waveforms and sensors. Q: The term “power” is fairly broad; what are the specifics? A: There are actually several basic […]
RF power measurement, Part 1: Why and where
When the subject is RF design, the word “power” dominates much of the discussion. This FAQ looks at some perspectives related to measurement of this vital RF parameter. Not only is power and measuring it among the most important RF design considerations, it is generally difficult to assess accurately, and it is getting harder […]
Working with bus analyzers
Protocol or bus analyzers (sometimes dubbed packet sniffers) are tools that intercept network traffic, store it, and then decode it for presentation in a human-readable state. Bus analyzers all have the same basic operating principle. They copy all network traffic out to a buffer or file. A lot of oscilloscopes include bus analyzer features. The […]
The RF power amplifier, Part 2: Considerations
Part 1 of this FAQ looked at the basic role and function of the RF power amplifier (PA). This part looks at some of the factors to consider when looking at possible PA devices. It is not a detailed run-through of the many parameters which characterize PAs, including many which are unique to the PA […]
Latest enhancements to LabVIEW NXG include WebVI, expanded instrument coverage
A new release of LabVIEW NXG, the next generation of LabVIEW engineering system design software, adds new functions and augments long-standing benefits, particularly for engineers developing, deploying and managing automated test and measurement systems. This release introduces the WebVI, a VI type for building web-based user interfaces (UIs) that can be deployed to any web […]
PXI chassis carries 58 W of power and cooling per slot
The PXIe-1095 chassis is the first PXI Chassis with 58 W of dedicated power and cooling per slot. This represents a 50% increase in power and cooling per slot compared to previously released NI PXI Express chassis. In addition to higher power, the new chassis also features a significant reduction in fan noise in its […]
High-res digitizers, co-processors come in PXI format
NI, the provider of platform-based systems that enable engineers and scientists to solve the world’s greatest engineering challenges, announced today a new PXI FlexRIO architecture that integrates mezzanine I/O modules with Xilinx Kintex UltraScale FPGAs. The first wave of products based on this new architecture includes two high-resolution PXI FlexRIO Digitizers, three dedicated PXI FlexRIO […]
The challenges of HIL testing and ADAS
Engineers running hardware-in-the-loop simulations face difficulties associated with how to devise sensor signals that truly exercise advanced drive assistance systems. DAVID A. HALL, National Instruments Corp. More than 50 years ago, in 1959, the Cadillac Cyclone XP-74 concept car featured two modified aircraft radars designed to alert the driver about oncoming traffic. Today, an automotive […]
Remote control module lets laptops run PXI systems via USB-C Thunderbolt 3
NI (National Instruments) announced today the PXIe-8301 remote control module, the industry’s first solution for laptop control of PXI systems using Thunderbolt™ 3. The PXIe-8301 offers PCI Express Gen 3 connectivity through two Thunderbolt 3 ports to maximize performance and delivers up to 2.3 GB/s of sustained data throughput. Engineers can use the second port […]
First SDR for 28-GHz research targets 3GPP and Verizon 5G standards
A series of 28-GHz radio heads have been developed by National Instruments Corp. for the mmWave Transceiver System. This combination creates the first commercially available full transceiver of its kind that can transmit and/or receive signals of up to 2 GHz of bandwidth in real time, covering spectrum from 27.5 GHz to 29.5 GHz. The […]
