Keysight 3-in-1 Programmable NFC Antenna

Another key element of Keysight’s test system is the 3-in-1 programmable NFC antenna. This

multi-coil antenna is available in three different fixed spacings:

– 5 mm (N2116A)

– 10 mm (N2134A)

– 15 mm (N2135A)

With this programmable antenna, testing can quickly progress from Listener mode to Poller

mode to Resonant Frequency test mode without having to manually or robotically move the

DUT from one antenna type to the next.
