NFC oscilloscope offers two-step test approach

An NFC oscilloscope unveiled by Comprion offers a selection of NFC and ISO triggers, individual envelope signal calculation. The NFC/ISO measurement features facilitate the evaluation of analogue NFC signals and consequently the development and integration of NFC-enabled devices

“Triggers can be configured on different levels, for example, for carrier modulation, NFC frame start/end, decoder I/O collision or commands like WUPA, to mention only a few of the over 100 trigger conditions. No other oscilloscope can offer that”  explains Ralph Kamp, Business Development Manager at Comprion.

The envelope calculation can additionally be configured and displayed immediately.

All this means that this oscilloscope can be used to measure signals according to NFC, EMVCo, or ISO very easily.

“At present you need a lot of expertise, time, and patience to find analogue interference signals in NFC communication using a traditional oscilloscope,” says Kamp. “It can take hours configuring the oscilloscope, importing the recorded data into an environment for analysis, calculating the envelope signal and offline decoding.”All this can make the search for a collision in the recording very tedious or even impossible."

Using the new integrated NFC oscilloscope by Comprion, it takes only two steps to reach the goal. Users set the high level trigger and start the measurement (single shot or continuous trigger). The envelope signal and the NFC measurement results are displayed immediately. “This simple approach allows for quickly going through a variety of scenarios with different combinations of analogue parameters,” Kamp adds. The NFC oscilloscope facilitates the work of test and development engineers significantly, in particular when they want to optimise the design of NFC-enabled devices or resolve communication issues on the analogue level.

It is important to identify and resolve problems as early as possible before they cause unnecessarily high costs in later stages of development.
