ADSL combination tester at a fair price: the ARGUS 42 plus tests ADSL, as well as optionally ISDN and POTS. In addition to the various access types and protocols, the tester also determines e.g. the attainable transmission speed or noise floor of the line.
Basic Triple Play tests are also supported: the ARGUS 42 plus can be upgraded to a fully featured voice tester if desired. The combination tester can then be used to set up voice calls to test and evaluate not only POTS and ISDN connections, but also calls placed via VoIP. The ARGUS 42 plus evaluates the voice quality, delivers a MOS value (using E model) and determines the Media Delivery Index (MDI) of IPTV streams.
The testing set also checks the resistance and capacitance and performs voltage measurements on top. Optionally, HF signals can be detected or data services can be tested, e.g. by enabling the passive bridge or router modes. This allows determining the transmission quality of the line.
The handheld tester, which weighs just 450 g, is remarkably user-friendly thanks to its intuitive menu structure.
