How to configure a external trigger at CMW500, CMW290, CMW270 to synchronize with LTE signal time frames

If a CMWrun test plan script has been fished the AC power of a CMW500 / CMW290 / CMW270 should be shut down automaticly.

During a CMWrun test my DUT fails on delivering isolated measurements using CMW270/290/500.

CMW500/290/270: No more WLAN signaling function after WLAN firmware update

How can a WiFi connection instead be made to a WiFi network for remote access of the CMW?

The CMW500/2xx shows a resource conflict in this situation when using in parallel the RFxCOM port and the RFxOUT port of the same RF-frontend.

Many manufacturers of Bluetooth® LE components find it challenging to test modules and sensors in compliance with the standard. These devices often have no connection for a control line, which is necessary for testing them in direct test mode (DTM) as stipulated by the Bluetooth® LE standard. The R&S CMW270 wireless connectivity tester from Rohde & Schwarz now enables over-the-air (OTA) tests on Bluetooth® LE devices, same as for Bluetooth® Classic devices, a function already implemented in the tester.

The R&S CMW270 wireless connectivity tester is the world’s first tester to emulate all IEEE 802.11a/b/g/n/ac standards, including 802.11ax.

The video demonstrates Bluetooth 5 measurements using the R&S CMW270 wireless connectivity tester.

The tried and tested R&S®CMW270 Wireless Connectivity Tester can be used to test the RF characteristics of receivers and transmitters, and to determine the data throughput in the transmit and receive directions. The R&S®CMW270 is the reference system for testing IEEE 802.11ax devices under realistic operation conditions.

Using the well-established R&S CMW270, developers can test the RF characteristics of both transmitters and receivers and also determine the data throughput in both directions.
