At productronica today Agilent Technologies strengthened its position in the wireless test set market with the launch of the E6640A. The new instrument can test up to 32 cellular and wireless-connectivity devices in parallel. It enables manufacturers the speed, accuracy and multi-port density to ramp up rapidly and optimise full-volume manufacturing.

To accelerate test development, the EXM is synchronised with the latest cellular and WLAN chipsets.

The EXM can be configured with up to four independent transmit/receive (TRX) channels, each of which is a complete vector signal generator and vector signal analyser. Each TRX includes four RF ports, two full-duplex and two half-duplex, to provide industry-leading port density. To further extend scalability and port density, it can be customised to connect up to 32 devices-under-test through multi-port adapter (MPA) technology.

The test set offers 160MHz bandwidth, up to 6GHz frequency range, and the broadest choice of multi-format coverage, from LTE-Advanced in cellular to 802.11ac with multiple-input/multiple-output (MIMO) in wireless connectivity.

To maximise production throughput, the test set is equipped with a quad-core processor, high-bandwidth PXIe backplane and advanced sequence analyzer capabilities. To further reduce test time, the EXM includes the ability to make multiple measurements on a single set of acquired data.

Superior signal quality and excellent measurement accuracy ensure improvements in first-pass yield. For example, power-level accuracy is a best-in-class ±0.5dB at 3.8GHz, and the receiver EVM noise floor is -42dBm for 802.11ac.
