Using Standard Setups and Presets

There are two ways to configure the VSA for RFID demodulation measurements: manually specify the demodulator protocol configuration parameters or select a preset standard format for your RFID system and the VSA will automatically set the protocol configuration parameters. Note that in some standards formats, the line coding will vary depending on the bit rate used.

The following list shows the standard protocol presets supported by the VSA. Entries followed by the notation "Beta" are preliminary releases. Click on the standard link to view the default parameter settings.
