Topic:

Mastering EVM: Optimizing to Industry Standards

Most industry standards have EVM performance in their specification. Part four of our “Mastering EVM” webinar series looks at some of these standard’s specific parameters.  Some protocols can have quite a few parameters. For example, the 4G and 5G 3GPP standards have grown to become more and more “flexible”. Settings have grown from a dozen to now 100’s, making your test setup more complex. 802.11, or WiFi, has many settings as well. Wifi also allows for variable data lengths and channel bandwidths. Longer data lengths allow more time for the generator or analyzer to drift. The larger the bandwidth, the lower the signal-to-noise ratio (SNR). 802.11, LTE & 5G allow several channels to be broadcast at the same time. In 802.11 it is called channel bonding; in 4G & 5G, it is called carrier aggregation. Either way, the transmitter is sending more than one channel at a time. This will degrade our EVM. Be sure to characterize EVM with single-channel and carrier aggregation combinations. This webinar explores how to use your EVM requirements to define your test instrumentation needs while making the most of your budget.
