89601EVMC Cross-Correlated EVM
Perform Cross-Correlated EVM measurement
Starting from
Perform Cross-Correlated EVM measurement.
Highlights
- Cross-correlated EVM is a technique used to extend the dynamic range of a receiver for best EVM performance
- Two receivers are used to capture and demodulate the same signal independently and performs cross-correlation on the error vectors to cancel out uncorrelated noise added by the receivers, resulting in a much lower EVM
- This technique causes the ccEVM value to primarily contain just the noise coming from the device under test (DUT)
- 89601EVMC option with VSA 2022 Update 1.0 release or beyond can enable accurate and best EVM performance of WLAN signals (requires WLAN 89601B7RC and/or 89601BHXC licenses)
- 89601EVMC option with VSA 2023 release or beyond can enable accurate and best EVM performance of 5G NR signals (requires 89601BHNC 5G NR license)
