RF Test And Measurement Resource Center

Time Domain Measurements Using Vector Network Analyzers Vector Network Analyzers (VNAs) are very powerful and flexible measuring instruments. Their basic capability is to measure the S-parameters of an RF or microwave device and display the result in the frequency domain. This provides valuable data for the design engineer to develop a design and for the production engineer to substantiate the performance of the device or system.
Testing LTE Release 9 Features
LTE – the fastest growing mobile radio standard – had its beginnings in 3GPP Release 8. Initial improvements and new features were implemented in Release 9. This Application Note describes the T&M methods for LTE Release 9 features using Rohde & Schwarz instruments.
Analyze EMI Problems with the R&S® RTO Digital Oscilloscope
In order to deal with electromagnetic interference (EMI) problems, the source of the unwanted emissions needs to be identified before a solution can be implemented. Testing at an EMC compliance laboratory can prove to be both slow and costly, and oftentimes, the information that comes back from the lab is a spectrum curve that indicates frequencies where emissions are critical of in violation of the limits.
Application Note: Power Measurements Anritsu’s handheld Site Master, Cell Master, BTS Master, Spectrum Master, and VNA Master products provide a wide range of modes and options for power measurements including the High Accuracy Power Meter, the Internal Power Meter, the External Power Monitor, and the Channel Scanner. Each Power Meter solution has its own unique strengths and benefits. The objective of this application note is to discuss the basics of these different power meter solutions and to explain how Anritsu’s handheld products can be used to make power meter measurements for different applications
Mobile WiMAX MIMO Multipath Performance Measurements
The mobile WiMAX™ TDD air interface according to IEEE 802.16™-2009 is promising a downlink gross user data rate of up to approx. 31,7 Mbit/s, when operating a 2x2 spatial multiplexing scheme, known as matrix B downlink MIMO, providing sufficient Signal-to-Noise Ratio. However, in real field operation, the data rate suffers of frequency and time selective propagation conditions, basically caused by multipath propagation and Doppler frequency shift. This application note describes a test setup to measure the packet error rate and throughput across the mobile WiMAX air interface including standardized propagation conditions.
