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 […]

Qualcomm certifies keysight equipment for 5G open RAN validation
Keysight Technologies, Inc. has achieved Qualcomm Development Acceleration Resource Toolkit (QDART) validation for the Qualcomm QRU100 5G RAN Platform from Qualcomm Technologies, Inc. This validation enables Open RAN Radio Unit (O-RU) and gNodeB (gNB) vendors to verify products using the Qualcomm 5G RAN Platforms throughout the design and production workflow. By separating software from hardware…
What is de-embedding and how do I perform it (part 2)?
When testing a device in a fixture, you can use transfer scattering parameters (T-parameters) to help remove the fixture’s contribution from your measurement result.
What is de-embedding and how do I perform it (part 1)?
It’s a tenet of the test-and-measurement industry that you should concentrate on looking for defects in your device under test (DUT) — not in your test equipment. Figure 1 illustrates a common problem. An instrument presents an incorrect reading; in this case, an LRC meter or multimeter presents a resistance reading that’s about 5% low. […]

Test applications handle automotive SerDes, MIPI A-PHY and ASA standards
New automotive serializer/deserializer (SerDes) transmit and channel test applications, as well as an automotive adapter portfolio to verify mobile industry processor interface (MIPI) A-PHY and Automotive SerDes Alliance (ASA) standards were developed by Keysight Technologies in collaboration with Sony Semiconductor Solutions Corp. and Rosenberger. High-speed automotive SerDes interfaces enable transport data streams to make in-vehicle […]
