Design Validation and Debug
Keysight’s InfiniiVision oscilloscope-based NFC test solution has several advantages over
traditional NFC one-box testers. During the design phase of NFC-based products, an
oscilloscope is a core test and debug instrument used by nearly all R&D hardware engineers.
Although the DSOXT3NFC/DSOX4NFC software runs on an external PC, the software
license resides in the scope. This is important because the license also enables special NFC
hardware trigger modes in the scope. This means that you can use the scope in a standalone
troubleshooting use-model without running the automated test software. The ability to trigger
on NFC communication can be an invaluable R&D debug tool.
Before moving an NFC-based device into production, design verification based on published
standards is important. Having an NFC test solution that can be quickly set up and provide
automated test results in the R&D environment, and then transfer the same test methodology
into the manufacturing test environment ensures consistency between all product development
and manufacturing test phases.
And finally, when things go wrong on the production floor, Keysight’s DSOXT3NFC/DSOX4NFC
software can be used on the repair line as well. If a specific test fails on the production line,
such as Poller NFC-B modulation depth, just that test can be selected to run on the repair line.
When the test is complete, the scope is configured for that particular debugging condition. This
enables the repair technician to quickly begin manual troubleshooting with the scope without
having to manually set up the scope for complex test conditions as shown in Figure 3.
