UTS7000A-FDD-LTE: FDD-LTE Demodulation Analysis

Overview

The UTS7000A-FDD-LTE software option provides 3GPP-compliant FDD-LTE signal analysis for engineers developing, manufacturing, or deploying LTE base stations and user equipment. FDD-LTE (Frequency Division Duplex) remains the dominant LTE deployment mode worldwide—the majority of LTE bands in the Americas, Europe, and parts of Asia use FDD. This option demodulates both downlink (eNodeB) and uplink (UE) signals per 3GPP TS 36.104, providing the EVM, constellation, resource block, and channel power measurements needed for standards compliance verification.

While 5G NR is deploying rapidly, FDD-LTE isn't going away—it continues as the anchor carrier for NSA (Non-Standalone) 5G deployments, handles VoLTE voice calls, and serves IoT devices that will remain on LTE networks for another decade. If you're involved in LTE infrastructure, device testing, or network deployment, this option provides the measurements you need.

What FDD-LTE Analysis Provides

EVM Measurement per 3GPP TS 36.104: Error Vector Magnitude is the primary modulation quality metric for LTE transmitters. The FDD-LTE option demodulates the signal, recovers the I/Q constellation, and computes EVM per the 3GPP specification—including the correct reference signal structure and equalization. This is different from generic VSA EVM measurement because the option understands the LTE frame structure: it knows where CRS (Cell-specific Reference Signals), PSS/SSS (synchronization signals), and PDSCH/PUSCH data are, and measures each correctly.

Per-Resource-Block Analysis: LTE allocates spectrum in resource blocks (180 kHz each). The FDD-LTE option reports EVM, power, and modulation type per resource block—revealing problems like edge-of-band roll-off, frequency-selective impairments, or incorrect power allocation across the channel. This granularity is essential during PA development and base station commissioning.

Downlink and Uplink Testing: The option supports both downlink (eNodeB transmission) and uplink (UE transmission) demodulation. Downlink analysis covers CRS, PSS, SSS, PCFICH, PDCCH, PHICH, PBCH, and PDSCH channels. Uplink covers PUCCH, PUSCH, and SRS. This dual capability means one option handles both base station manufacturing test and UE development.

ACLR Testing: Adjacent Channel Leakage Ratio is the critical spectral emission measurement for LTE transmitters. While the AMK option can measure ACPR for any signal, the FDD-LTE option provides standards-compliant ACLR measurement with the correct 3GPP channel and offset bandwidth definitions—including E-UTRA and UTRA ACLR values required for regulatory compliance.

Frequently Asked Questions

Do I need both FDD-LTE and TDD-LTE options?

Only if you work with both duplex modes. FDD-LTE covers bands like 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 20, 25, 26, 28, 66, and 71—the majority of deployed LTE bands in the Americas and Europe. TDD-LTE covers bands 38, 39, 40, 41, 42, 48—primarily deployed in China and for CBRS (band 48) in the US. Check which bands your products or networks use to determine which option(s) you need.

What bandwidth option do I need for LTE testing?

LTE carriers are 20 MHz maximum, so the standard 20 MHz real-time bandwidth is sufficient for single-carrier testing. For carrier aggregation (2+ carriers simultaneously), you'll need a bandwidth option: B40 for 2×20 MHz, B85 for 3-4 carriers, B160 for more extensive aggregation scenarios. Note that the FDD-LTE demodulation itself operates on one carrier at a time regardless of bandwidth option.

3GPP-compliant FDD-LTE EVM, constellation, and resource block analysis—the standard isn't going away, and neither should your test capability.
