EW receiver mission data files can contain hundreds of emitters with thousands of modes and beams that must be tested by simulation at RF. Often, these emitters, their modes and beams are listed on intelligence databases and must be imported from a spreadsheet into to an emitter simulation application such as the R&S®Pulse Sequencer software. For this purpose, the R&S®Pulse Sequencer software offers an internal script editor which allows to import user data and automatically generate emitter, sequence or platform configurations that can then immediately be played into RF without any additional software. Furthermore, the R&S®Pulse Sequencer offers a SCPI recorder tool to collect manual entries during scenario data creation into a list of corresponding SCPI commands. This list of commands can easily be used to create user defined scripts that can either run in the internal script editor or an external software (e.g. Matlab, Python).

Analyzing high speed datacom interfaces is an important task and ensures signal integrity. One major challenge of this analysis is the connection between the physical interface and the oscilloscope, as most of the datacom interfaces do not provide test connections suitable for RF. A test fixture is required as a bridge between the high speed datacom IF and the RF connector of the oscilloscope, but this will affect the signal integrity measurement. The R&S®RTP and R&S®RTO oscilloscopes with the advanced jitter option can analyze and separate jitter contributions. Additionally, the option can evaluate the impact of test fixtures and traces inherently and give the user a good understanding of the impact of their test setup.

Road safety is a global challenge at present and will be in the future. Automotive radar has become a keyword in this area and pushes again a step forward to increase driving comfort, crash prevention and even automated driving.Driver assistance systems which are supported by radar are already common. Most assistant systems are increasing the drivers comfort by collision warning systems, blind-spot monitoring, adaptive cruise control, lane-change assistance, rear cross-traffic alerts and back-up parking assistance.Today's 24 GHz, 77 GHz and 79 GHz radar sensors clearly need the capability to distinguish between different objects and offer high range resolution. That is possible with increased signal bandwidth.Furthermore, those radar systems need to cope with interference of many kinds like the one from other car's radar.This Application Note addresses signal measurements and analysis of automotive radars that are crucial during the development and verification stages.

Using option ZVR-B4 (Frequency Converting Measurements), a ZVR Vector Network Analyzer can be used for measurements on frequency converting devices such as mixers and amplifiers. Using the ZVR's ARBITRARY mode, the source and receiver frequency ranges of the ZVR's generator and receiver, plus for two external signal generators, can be defined independently. As a result, mixer and intermodulation products such as conversion loss or sampling mixers, can all be measured. Used together with option ZVR-B6 (Reference Channel Ports), group delay measurements can also be made on frequency converting devices.
