The constantly decreasing size of components and the available board space form a challenge to place adequate test connections for RF instruments. Recent improvements in the availability and use of high performance differential building blocks in RF circuits intensify the problems of connecting test equipment. Using oscilloscope probes is a possibility to perform measurements by connecting to printed circuit board lines and chip contacts where only a minimal area is required to make contact. This application note provides information on how to use oscilloscope probes in RF measurements using spectrum analyzers, and show the results of differential measurements with a spectrum analyzer.

EW receivers are tested in the lab at RF to discover problems before flight testing. This eliminates cost and schedule risk. Flight testing can cost tens of thousands of dollars per hour and must be scheduled many months in advance. In contrast, using test equipment to test at RF might require a certain upfront cost but provides a readily-accessible capability to simulate radar threats at RF for a long time. This application note explains how the angle-of-arrival (AoA) capabilities of EW receivers can be tested with commercial off-the-shelf (COTS) RF test equipment. Topics covered are the generation of scenarios, instrument setup, and setup calibration. We will use a radar warning receiver (RWR) as a proxy for a generic EW receiver in this application note.

Measurements of very high noise figure components are performed for a number of reasons. For instance, in a wide range of applications, devices under test (DUT) are characterized within a complex test setup that includes high losses before or after the low noise DUT. In case of high frequencies, the switch matrix with complex signal routing and cables might have a very high loss. In other cases, the device might be embedded in a test setup where direct access is physically impossible, on-wafer probing is one example for this case. Using conventional measurement equipment, the noise figure measurement of such a device is very unstable if not impossible at all.

Using a Vector Network Analyzer from the ZVR family, not only magnitude and phase can be measured, but also group delay and even phase delay. Whereas phase delay measurements produce the highest accuracy for the electrical length of non-dispersive devices under test, such as coaxial cables, group delay measurements also give a detailed insight into the frequency dependent delay characteristics of dispersive devices, such as filters. In addition to the traditional step aperture technique, Vector Network Analyzers from the ZVR family offer a frequency aperture technique, which allows a well defined and constant aperture for group delay measurements also for a nonlinear frequency sweep.
