PXI switching modules handle heavy ac and dc loads
A new high-power relay PXI module provides the industry’s highest switching capacity in the smallest footprint for a solution based on electromechanical relays. Occupying a compact single PXI slot form factor, the model 40-166 is available with SPST, SPDT or SP4T switching configurations. It uses power relays suitable for switching loads up to 20 A […]
Rugged ATR chassis for VITA 48.4 features liquid flow-through cooling
A new rugged ATR chassis compliant with VITA 48.4 for liquid flow-through (LFT) cooling includes a new backplane designed for data rates up to 10 Gbps and can handle 300 W per slot. This enables the system to accommodate the intense thermal management needed in high-density embedded computing systems. The new chassis offers several other […]
Product review: Pico VNA 108 8.5-GHz vector network analyzer
The vector network analyzer (VNA) is an advanced member of the oscilloscope family of electronic instruments. The DUT may be as simple as a single resistor or conductor. The VNA can also operate as a time domain reflectometer, measuring the distance to and nature of a fault, impedance anomaly, complete break or short in a […]
RF signal generator puts out 500 mW
The Rigol DSG3000B RF Signal Generator series improves on the DSG3000 series, covering a frequency range of 9 kHz to 6.5 GHz or 13.6 GHz and includes IQ modulation variants. These HF signal sources have an amplitude accuracy of
NI CEO: COVID-19 on day one
NI CEO Eric Starkloff’s first decision was what to do about COVID-19 the night before he took over on February 1, 2020. Since then, he’s seen the opportunities in communications resulting from the pandemic. How would you like to take on a new leadership role just as a pandemic takes hold? That’s what Eric Starkloff […]
Signal quality analyzer gets expanded PCIe receiver test capabilities
The MP1900A BERT Signal Quality Analyzer-R now has expanded PCI Express (PCIe) receiver test capabilities to support emerging PCIe 6.0 designs using PAM4 32-Gbaud technology. With the upgraded high-quality waveform performance of the PAM4 pulse pattern generator (PPG) MU196020A, the MP1900A can conduct PCIe receiver tests on high-end servers, high-performance computers, 400 GbE communications equipment, […]
Basics of measuring fuel cells
A fuel cell converts oxygen or another oxidizing agent and hydrogen or some other fuel into electricity and heat. A third byproduct, depending on the fuel used, is methane or another non-earth-friendly substance. But the most basic fuel cell combines hydrogen and oxygen to produce pure water. This simple, long-lasting device with no moving parts […]
T&M upgrades support coherent module, silicon photonics test applications
VIAVI has released six major enhancements to the LightDirect family of modules for the MAP-300 test platform, which was introduced last year, with specific focus on supporting coherent module and silicon photonics test applications. · New high power, C+L band, continuously tunable laser module, the mTLS-C1, the most compact on the market for its performance […]
