N9082B LTE/LTE-Advanced TDD Measurement Application

Signal analysis

• LTE and LTE-Advanced TDD per 3GPP release 8 to 12
• Uplink and downlink RF transmitter conformance measurements in a single option
• Carrier aggregation (CA) with up to five component carriers (CCs) in both contiguous and non-contiguous configuration
• Improved spectral efficiency with higher order demodulation to 256QAM

Measurements

• Output power level: channel power, transmit On/Off power
• Transmitted signal quality: EVM, frequency error, time alignment error, RSTP, OSTP, I/Q offset, spectral flatness, and more. Pinpoint signal impairments with color-coded traces like EVM vs. symbol, EVM vs. subcarrier, detected allocations (subcarrier vs. symbol), constellation diagram, and frame summary
• Unwanted emissions: SEM, cumulative SEM, ACLR, cumulative ACLR (CACLR), OBW, spurious emissions, transmitter intermodulation
• All measurements are available for single carrier (LTE) and multi-carrier/CA (LTE-Advanced) with contiguous or non-contiguous allocations as defined by 3GPP

RF transmitter testing

• Simplify measurement setup with automatic detection of downlink channels and signals. For eNB conformance testing, measurement is simplified by recalling E-TM presets, for each carrier, according to 3GPP TS 36.141 conformance document.
• Perform measurement on all LTE/LTE-Advanced channel bandwidths with ability to view measured results – of up to 5 CCs for LTE-Advanced- in multiple domains such as resource block, sub-carrier, slot, or symbol. Graphical displays with color coding and marker coupling allows you to search for problems faster and troubleshoot the found problems quicker.
• Test beyond physical layer by using the transport layer decoding functionality. Troubleshoot transport layer problems and verify the channel encoding is correct by getting access to data at different points in the receiver chain such as: demapped, deinterleaved, descrambled, deratematched and decoded data.
• Add real-time spectrum analyzer (RTSA) capability to the PXA or MXA signal analyzers to pinpoint interference caused by other transmitters in the operating band or other events such as cross-modulation of component carriers in the transmitter.
