Added options for MXA signal analysers target LTE channels

Agilent recently unveiled new options for its midrange N9020A MXA X-series signal analyser. I recently spoke with Sai Yang, product manager in Agilent Technologies' microwave and communications division, about these new updates.

The expanded options include 160MHz bandwidth and a real-time spectrum analyser. Both can be applied to existing MXA signal analysers. The company developed the wider bandwidth in order to satisfy WLAN and LTE channel bandwidth requirements (larger channel numbers require wider analysis bandwidth).

A notable spec for this product is its IF performance. For instance, EVM for 802.11ac demodulation of 0.3 per cent is -50dB, which is on par with high-end signal analysers. The RTSA option is the feature that was introduced earlier this year on the company's PXA series, and it is now available on the mid-range MXA, which allows designer so see frequency-hopping series as well as interference and transition signals.

Yang points out that, "Adding real-time capabilities to new or existing MXAs is 1/7th the cost of a dedicated real-time analyser."

The RTSA and analysis-bandwidth options are available as upgrades to existing analysers. The compatibility of bandwidth upgrades depends on the existing configuration of the analyser.

Further information regarding the MXA X-series signal analyser can be found here.
