CPRI analyzers display multiple traces

-March 11, 2017

Anritsu has enhanced its CPRI RF field analyzers to address the requirements associated with testing high-speed LTE base stations. Available on select Site Master, BTS Master, Spectrum Master, and Cell Master instruments, enhancements include the ability to display four unique AxC traces, support for CPRI Line Rate 8 (10.1376 Gbps), and 20-MHz compression.

Multitrace AxC capability enables the analyzers to show four AxC traces in a single or dual display configuration. Multitrace AxC and dual display permits simultaneous viewing of different MIMO signals, which also allows for RF diversity testing between MIMO radios on a live signal. BTS Master models with two SFP ports can display AxC traces from two fiber connections and present a different bandwidth signal and line rate per diplay, so spectrum and spectrogram measurements can be made on co-located radios at different frequencies.

The 20-MHz compression implemented by newer baseband units is also supported by the handheld analyzers. This compression capability allows for resampling of 20-MHz IQ data signals from 30.72 Msample/s to 23.04 Msamples/s for a 25% reduction.

These latest enhancements are for the BTS Master MT8220T, MT8221B, and MT8222B base station analyzers, as well as the E series of Site Master cable and antenna analyzers, Spectrum Master spectrum analyzers, and Cell Master base station analyzers.
