WLAN 802.11ac signal generation and analysis added to tester

Aerofex has added IEEE 802.11ac capability to its mid-range S-Series RF signal generator and analyzer product line.

Designed for use in wireless local area network (WLAN) research, design, and manufacturing, the new 802.11ac capability is available for the SGD RF digital signal generators (Option 119) and the SVA vector signal analyzers (Option 110).
The S-Series product lines standard features include bandwidth at 200 MHz; level and frequency settling times of100s; and very low phase noise performance (-135 dB/Hz at 1 GHz, 20 kHz offset), all in 4U height and half-rack width.
The S-Series wide bandwidth is ideal for WLAN R&D. For manufacturing, the fast settling times enable rapid device throughput. The large touch-screen and innovative user interface make complex measurements quick and easy. Using Aerolock, the S-Series instruments can be locked together to build complex test set-ups. T
The need for increased device speed, data rates, network capacity, and wide bandwidth have put pressure on the instruments hardware to maintain modulation accuracy and increased bandwidth. The S-Series is highly accurate and with 200 MHz factory-calibrated bandwidth, we can easily cover the needs of 802.11ac with plenty of room for future technologies.
The WLAN signal generation suite is now updated for 802.11ac, supporting bandwidths of 20, 40, 80, 80+80 and 160 MHz and up to 8 spatial streams. Using an embedded version of Aeroflexs IQCreator waveform creation software, 802.11ac waveforms are quickly created and played from within the signal generator. Modulation schemes up to 256QAM are supported with excellent residual EVM (Error Vector Magnitude) to help customers pinpoint the exact nature of their signal degradation and identify the source of the problem.
