A new test suite handles the TR-398 Issue 2 Wi-Fi router performance test standard from the Broadband Forum. Customer care calls and truck rolls associated with Wi-Fi are a big pain point for service providers. They are looking for testing solutions that help them quantify the performance of a Wi-Fi router prior to releasing it […]
Test and Measurement Tips
Scope test setup complies with IEEE 802.3ch MultiGBASE-T1 Automotive Ethernet standard
The new K88 option for R&S RTO and R&S RTP oscilloscopes from Rohde & Schwarz enables compliance testing on the next evolution of the automotive Ethernet standard. The new IEEE 802.3ch standard addresses the need for high speed networking and data transfers within the car. With the K88 software option, Rohde & Schwarz continues to […]
The difference between an electrometer and a Geiger counter
In 1895 William Roentgen observed X-rays although he could not explain their mechanism. The following year Henri Becquerel demonstrated that certain compounds of uranium emitted radiation that resembled X-rays. He showed this activity differed from the phenomenon of phosphorescence. The radiation seemed to be emitted continuously from the uranium. Did this violate the well-known principle […]
Vector network analyzers feature up to 67 GHz frequency range
The R&S ZNA newly introduced models cover frequency ranges of up to 50 GHz and 67 GHz. The R&S ZNA features excellent RF performance, including wide dynamic range and extremely low trace noise, and comes with a user-friendly, purely touch based GUI. Its unique hardware platform offers up to four internal, phase coherent sources plus […]
Non-contact voltage true-rms ac/dc clamp meters measure voltage, current simultaneously
The new Fluke 377 FC and 378 FC Non-Contact Voltage True-RMS ac/dc Clamp Meters are the only clamp meters that make accurate non-contact voltage measurements without test leads. The Fluke 377 FC and 378 FC True-rms clamp meters use Field-Sense technology to make testing faster and safer, all without touching a live conductor. You get […]
Testing Wi-Fi 6E performance
The 6 GHz band brings 1,200 MHz of additional spectrum to Wi-Fi which complicates the task of testing a verifying features. Eve Danel, LitePoint Now that the 6 GHz region of the spectrum is available for unlicensed use, Wi-Fi 6E devices are on their way to store shelves. Manufacturers face the juggling act of comprehensively […]
The difference between TDR instruments and scope-based TDR measurements
Often a transmission line is buried, concealed behind finish surfaces, or otherwise not readily accessible. So it is difficult to locate faults by means of visual inspection. It is, however, feasible to locate such discontinuities via a test instrument known as the time domain reflectometer (TDR). The TDR is sometimes compared to a radar installation, […]
New 10-slot 3U development chassis for OpenVPX, SOSA designs
A new 10-slot 3U OpenVPX enclosure system is geared for SOSA (Sensor Open Standard Architecture) requirements. The new chassis platform features removable sidewalls, allowing the open frame enclosure to be optional fully enclosed. The 10-slot backplane has clocking and VITA 46.11 system management connections per SOSA requirements. It has multiple VITA 67.3c and VITA 67.3d […]
ARB waveform generators and measuring amplifier gain
When it comes to amplification, the principal parameters are gain and fidelity of the output relative to the input. Gain, denoted by β (Greek letter beta), is the ratio of output voltage, current or power to input. An amplifier by definition has a power gain greater than one. Measurements that characterize amplifier gain serve as […]
Wideband 20 GHz amplifier provides +30 dBm output
The Tabor A10200-DST Wideband Signal Amplifier is a new high-frequency module with 100 kHz to 20 GHz bandwidth, a gain of 8-10x, an output power of +30 dBm into 50 Ω, with transition times of less than 10 nsec. The Model A10200-DST HF Amplifier is an ultra-small-footprint, wideband, RF signal amplifier designed for high frequency, […]
