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.
