The Anritsu MS2830A/MS269xA Vector Signal Generator hardware can be used to generate or replicate live scenarios in the laboratory. Fading test scenarios such as those defined in ETSI TS 103 257 are also supported.
Interoperability and field testing
Interoperability events aim to provide essential feedback to technical committees to help improve the standards and to accelerate the standards-making process, and several events are organised every year in the different regions. These events also enable engineers to get together to test the interoperability of their implementations: a process which can reduce a product’s time-to-market. In addition to interoperability, each commercial device has used a high number of hours of field testing to guarantee that its performance is not affected when the device is taken out of the laboratory or computer simulations, and put into real operation mode involving uncontrollable external factors.
One issue that engineers face in test events or during field testing is the need to record and replicate field situations in the laboratory. A capture and replay system such as that available in the Anritsu MS2830A and MS269xA Signal Analyser series can be used to capture, store and replay data in the laboratory or in the field in a single-box solution. Furthermore, using the Anritsu V2X message viewer, the captured data can be analysed and debugged packet by packet (Figure 2).
