WiGig or IEEE 802.11ad is an emerging standard aimed at providing data throughput speeds of up to 7 Gb/sec. To achieve these speeds over limited distances, the 802.11ad PHY layer uses frequencies in the unlicensed 60+ GHz spectrum. The high frequencies involved – up to 65.80 GHz in some markets – have presented a number test and measurement challenges, including the need for multiple instruments that must be calibrated together and difficult cross-domain debugging due to the frequencies involved.
Engineers at the Tokyo Metropolitan Industrial Technology Research Institute (TIRI) were among those struggling with the complexity involved with WiGig measurements. In their quest to find a more efficient approach, TIRI has now turned to a DPO70000SX oscilloscope powered by the recently introduced SignalVu Option SV30.
Taking advantage of the DPO70000SX oscilloscope’s unique low-noise ATI acquisition technology, Option SV30 offers 2.5 percent (-32.0 dB) error vector magnitude (EVM) precision for the industry’s most accurate solution with a single instrument that uses zero down-conversion. Competitive offerings require down-conversion and the need for at least two instruments that must be calibrated decreasing accuracy and increasing set-up time.
As detailed in the video below, TIRI previously had to use two downconverters and one oscilloscope to for millimeter wave analysis. Now with the Tektronix DPO70000SX, which can measure up to 70 GHz – more than enough to measure WiGig signals – TIRI’s engineers can “instantly understand” the status of their signals, adjust the equipment, discover flaws seamlessly and they no longer need to use multiple devices.
