RF cables cover frequencies to 43.5 GHz for test applications
Cables available in three standard lengths with SMA, 2.92 mm, and 2.4 mm end connectors. Samtec’s LL043 Series Nitrowave microwave cable assemblies have performance is optimized from DC to 43.5 GHz with a maximum VSWR of 1.4:1. The 43.5 GHz bandwidth lets the cables operate at 5G mmWave frequencies as well as those used in […]
Verify, test, and troubleshoot 5G Wi-Fi FWA gateways
By Xiang Li, Keysight Technologies Follow these three steps to ensure your fixed-wireless access designs will be compatible with the Wi-Fi fronthaul and 5G backhaul. Many areas lack the wired infrastructure to bring residential broadband access. Making those connections has become costly and inefficient. Fixed Wireless Access (FWA) has emerged as a compelling alternative to […]
Should I use a spectrum analyzer, signal analyzer, or vector network analyzer? Part 4
A vector network analyzer can fully characterize components by deriving their scattering parameters. In earlier parts of this series, we looked at analog spectrum analyzers (part 1 and part 2) and vector signal analyzers (part 3), both of which monitor unknown signals, whether emanating from a system, device under test (DUT), or an enemy’s transmitter […]
IMS 2024 roundup: test equipment
Washington, DC — The 2024 International Microwave Symposium took place here in June at the Walter E. Washington Convention Center. As always, RF/microwave/mmWave test equipment was all over the exhibit hall. Frequency-domain test equipment — spectrum analyzers, vector network analyzers, power meters, and signal generators — were, of course, dominant. Other equipment, such as oscilloscopes […]
How can I quantify a device’s nonlinearity? part 1
You can specify nonlinearity in parts per million or, especially for RF components, in terms of the 1-dB compression point or third-order intercept point.
Spectrum measurements shed light on sign malfunctions
Interference in the 900 MHz band appears to produce random errors in a gas station price sign. Spectrum analyzers help track it down. I received a call recently from a former client who manufactures electronic signs. A gas station was experiencing intermittent loss of wireless control of its signs, which displayed the price of various […]
Perform phase noise and VCO measurements to 50 GHz
Rohde & Schwarz bumps up the frequency with the FSPN50 phase noise analyzer and VCO tester.
Wi-Fi 7 approaches, now comes the testing
Keysight’s E7515W lets you test Wi-Fi 7 chipsets and systems.
AOC 2023: Exhibits show the latest in military wireless
Washington — The Association of Old Crows (AOC) held its 60th annual convention in Washington during the week of December 11, 2023. EE World was there on December 12. Here is some of what we saw in the exhibit hall. AOC is a defense-oriented conference that focuses on military wireless communications. In addition to product […]
