Scalable wireless testing optimized for high-volume production

Keysight wireless test sets are now offered in one capability class, the VT4-class, and include the E6600 Series wireless test sets. These test sets streamline R&D and manufacturing testing of wireless devices that support multiple standards — including 5G New Radio (NR), Wi-Fi® 802.11ax, and WLAN — all within a single platform. Optimized for high-volume production, these test sets deliver high throughput through higher-level hardware capabilities and robust software automation, reducing delays and maximizing efficiency. Their modular, scalable design adapts to evolving test requirements while simplifying setup and integration. Choose one of our popular configurations or configure one specific to your application.

Automation-ready

Enables fast, automated device calibration and final verification through high-speed hardware sequencing and software automation, ideal for high-throughput manufacturing.

Multistandard support

Supports various standards like 5G NR, LTE, Wi-Fi 802.11ac / ax, WLAN, Bluetooth®, and Zigbee® for efficient testing of complex, multi-radio wireless devices.

Modular architecture

Supports up to 32 ports and four transceivers within a single chassis, enabling simultaneous multidevice or multiport testing for maximum throughput and efficiency.

Built-in switching

Internal switching simplifies test setups by eliminating the need for external hardware, enabling flexible configurations, and supporting multiple devices and antennas.

Highlights

The E6681A EXM-WB wireless test set is the optimal solution for 5G FR2 manufacturing test. The EXM-WB hardware is ready for tomorrow with up to 1.2 GHz bandwidth and supports all FR2 bands defined by 3GPP for 5G NR operation up to 43.5 GHz when coupled with the M1740A mmWave transceiver for 5G, a remote radio head (RRH). Compact and flexible, 1 or 2 transceivers in a single PXIe chassis provide many configurations to implement a useful test strategy.

  • The application software is familiar and industry proven. Test 5G FR2 devices confidently with Keysight’s common measurement algorithms and waveforms. Chipset control, sequencing, and parallel test make it easy to optimize throughput on production lines. Minimize test development time by re-using existing code from other Keysight non-signaling platforms like the E6640A EXM wireless test set. A controller embedded within the E6681A makes startup quick and painless with software licenses and applications pre-installed before shipment.
  • Keysight’s E6681A EXM-WB is optimized for 5G manufacturing test. Hardware and software support:
  • 300, 600, or 1.2 GHz bandwidth
  • 24.25 to 29.5 GHz and 37 to 43.5 GHz frequency ranges, covering all five of the FR2 bands defined today by 3GPP (requires connection to M1740A RRH)
  • 5G NR and optional mmWave antenna characterization software applications
  • Chipset control, sequence analyzer, source list, and parallel test
  • Power, SEM, ACLR, EVM, and more measurements and analysis
