  • Accelerate measurements with one-button RF conformance tests as defined by 3GPP TS 36.141 and 36.521 specification
  • Analyze carrier-aggregated signal of up to 5 contiguous/noncontiguous component carriers
  • Pursue improved spectral efficiency with higher-order demodulation to 256 QAM
  • Use multi-touch interface and SCPI remote interface
  • Extend test assets with transportable licenses between X-Series signal analyzers with multi-touch UI 

LTE/LTE-Advanced FDD and TDD Measurement Applications

The LTE/LTE-Advanced FDD and TDD measurement applications transform the X-Series signal analyzers with multi-touch into 3GPP LTE/LTE-Advanced standard-based RF transmitter testers. The applications provide fast, one-button RF conformance measurements to help you design, evaluate, and manufacture your LTE and LTE-Advanced base stations (eNB) and user equipment (UE). The measurement applications closely follow the 3GPP standard, allowing you to stay on the leading edge of your design and manufacturing challenges.

X-Series Measurement Applications

X-Series measurement applications increase the capability and functionality of Keysight Technologies, Inc. signal analyzers to speed time to insight. They provide essential measurements for specific tasks in general-purpose, cellular communications, wireless connectivity applications, covering established standards or modulation types. Applications are supported on both benchtop and modular, with the only difference being the level of performance achieved by the hardware you select.

Top Features

With the LTE/LTE-Advanced FDD and TDD measurement application, you can perform RF transmitter measurements on eNB and UE devices in time, frequency, and modulation domains. Measurement setups are simplified with automatic detection of downlink channels and signals. For eNB conformance testing, measurement is simplified by recalling E-TM presets according to 3GPP TS 36.141 specifications.

NB-IoT Downlink Measurement

NB-IoT downlink modulation analysis measurement showing constellation, spectrum, Error Summary, Frame Summary, EVM vs. subcarrier and EVM vs. Time. Measurements are color-coded on different physical channels and physical signals such as NPSS, NSSS, NPBCH, NPDCCH and NPDSCH. Up to 12 markers with marker coupling between different measurements are available for easier troubleshooting.

NB-IoT Uplink Measurement

NB-IoT uplink modulation analysis measurement showing constellation, spectrum, Error Summary, Frame Summary, EVM vs. subcarrier and EVM vs. Time. Measurements are color-coded on different signal type data or DMRS. Up to 12 markers with marker coupling between different measurements are available for easier troubleshooting.

eMTC Uplink Measurement

eMTC uplink modulation analysis measurement showing constellation, spectrum, Error Summary, Frame Summary, EVM vs. subcarrier and RB detected allocation. Measurements are color-coded on different signal type data (QPSK, 16QAM, 64QAM) or DMRS. Up to 12 markers with marker coupling between different measurements are available for easier troubleshooting.

Measurement Details

All of the RF transmitter measurements as defined by the 3GPP standard, as well as a wide range of additional measurements and analysis tools are available with a press of a button. These measurements are fully remote controllable via the IEC/IEEE bus or LAN, using SCPI commands.

Analog baseband measurements for LTE/LTE-Advanced are available on a PXA or MXA signal analyzer equipped with BBIQ hardware. Supported baseband measurements include all of the modulation quality plus I/Q waveform measurement.

It is important to note that the measurements shown in the LTE FDD and TDD tables are available for a single carrier, while the measurements for LTE-Advanced FDD and TDD columns are available for multiple carriers with up to 5 component carriers.

Key Specifications

Definitions

  • The specifications apply to single carrier case only, unless otherwise stated.
  • 95th percentile values indicate the breadth of the population (≈2σ) of performance tolerances expected to be met in 95% of cases with a 95% confidence.
  • Typical values are designated with the abbreviation "typ." These are performance beyond specification that 80% of the units exhibit with a 95% confidence.
  • Nominal values are designated with the abbreviation "nom." These values indicate expected performance, or describe product performance that is useful in the application of the product.

Software Licensing and Configuration

Choose from two license types:

  • Fixed, perpetual license:

This allows you to run the application in the X-Series analyzer in which it is initially installed.

  • Transportable, perpetual license:

This allows you to run the application in the X-Series analyzer in which it is initially installed, plus it may be transferred from one X-Series analyzer to another.
