Three hardware modifications of the option External Measurements ZVR-B25 enable the bidirectional network analyzers of the ZVR-family to carry out 4-port measurements. For the measurements, the four ports PORT 1, PORT 2, INPUT b1 and INPUT b2 at the front panel of the ZVR(E) are utilized. The fifth connector, ie OUTPUT a1, is not required for this purpose. As detailed below, the necessary modifications of the test set of the analyzer are described for the model ZVR. Of course, the modifications can be done in a similar way for the model ZVRE as well.

Drivers rely more and more on advanced driver assistance systems (ADAS) based on radar technology. The radar sensor delivers information about the surrounding traffic environment. It is a must for every radar sensor to detect wanted signals from real objects also in the presence of unwanted interferers. The R&S®AREG100A provides a powerful solution for testing the immunity of radar sensors against interferers.

This application note reviews a new calibration subsystem which consists of Inline Calibration Units (ICUs). These ICUs are designed for in situ use, so they are left in place both during the calibration procedure and during the measurement of the Device Under Test (DUT).This adds versatility, convenience and accuracy to the VNA based measurement system, as it means the calibration can be refreshed at any time without manually disconnecting the DUT from the test system.

Secondary surveillance radar (SSR) bridges the gap between communications systems and classic radar systems. Despite the increasing capabilities of mobile communications, SSR remains a major component in airspace surveillance. State-of-the-art methods such as Mode S reply enhance SSR with broadcast-like capabilities and enable airports in remote locations to surveil the airspace even if no radar is available. More advanced techniques such as automatic dependent surveillance broadcast (ADS-B) utilize the infrastructure provided by a Mode S reply transponder to provide even more information for ground control and other aircraft.

TDMA communications systems like GSM, DCS 1800 or PCS 1900 make effective use of the frequency spectrum by assigning several subscribers to the same frequency channel. Each subscriber has access to one predefined time slot for transmitting information. With GSM eight subscribers share one frequency channel with a bandwidth of 200 kHz. In order not to disturb the other users of the 200-kHz channel it has to be ensured that, for instance, a mobile sends in the assigned time slot only and that no power is emitted by the transmitter at other times. For this reason the transmitter power is practically switched off in the transmission intervals.
