17.4 NFC trigger
The Near Field Communication (NFC) trigger triggers on characteristic events of NFC
signals, in particular on polling requests of a device, for example, of a mobile phone.
The trigger source is the NFC signal connected to one of the channel inputs.
You can analyze the triggered signal in two ways:
●
In normal instrument mode, you can display and analyze the signal in the time
domain.
●
In IQ mode, you can acquire and save I/Q data for external analysis on a computer.
The R&S RTO6 display shows the magnitude of the I/Q vector.
Access: "Menu">"Trigger" > "Setup" tab > "Type = NFC"
