Keysight Technologies

Signal Studio for 802.15.4g Wi-SUN N7610B

Technical Overview

• Create Keysight validated and performance-optimized reference signals compliant to IEEE 802.15.4g (Wi-SUN) PHY standards
• Support mandatory profiles for MR-FSK and MR-OFDM PHY mode respectively
• Provide signals with full channel coding, flexible configuration of MAC headers and data types for testing receivers
• Accelerate the signal creation process with a user interface based on parameterized and graphical signal configuration and tree-style navigation

Simplify 802.15.4g Wi-SUN signal creation

Keysight Signal Studio software is a flexible suite of signal-creation tools that will reduce the time you spend on signal simulation. For 802.15.4g Wi-SUN, Signal Studio’s performance-optimized reference signals—validated by Keysight—enhance the characterization and verification of your devices. Through its application-specific user-interface you will create standards-based and custom test signals for component, transmitter, and receiver test.

802.15.4g PHY conformance tests

N7610B Signal Studio for 802.15.4g provides advanced capabilities to enable you to create fully channel-coded signals for receiver packet-error-rate (PER). Applications include:

• Performance verification and functional test of receivers, during RF/baseband integration and system verification
• Coding verification of baseband subsystems, including FPGAs, ASICs, and DSPs
• Wi-SUN PHY conformance tests

Its graphical interface provides a direct instrument connection for parameter transfer and closed-loop or interactive control during signal generation.

Apply your signals in real-world testing

Once you have set up your signals in Signal Studio, you can download them to a variety of Keysight instruments. Signal Studio software complements these platforms by providing a cost-effective way to tailor them to your test needs in design, development and production test.

• Vector signal generators
  MXG and EXG X-Series
  PSG and ESG Series
• PXIe vector signal generator

Signal Studio’s advanced capabilities address applications in IEEE 802.15.4g requirements and Wi-SUN conformance tests for receiver designs in all stages of development. Use the baseband signal to perform demodulation and decoding verification on ASIC and DSP chips. To thoroughly test the demodulation capabilities of a receiver, a fully-coded test signal is necessary. This level of coding enables you to determine if each functional stage of a receiver is operating correctly and enables you to use this test signal to perform PER measurements.

• Support multi-rate and multi-regional frequency and multi-data rates combinations defined in IEEE 802.15.4g specifications
• Support Wi-SUN MR-FSK and MR-OFDM of SUN PHY formats
• Set SHR and PHR in relevant tests separately
• Configure MAC header settings, MAC FCS, sequence control, data type, and data length
• Provide impairment tests with Symbol Timing Error, Frequency offset, and Frequency deviation

Features Summary

Supported Standards and Test Configurations

Performance Characteristics

The following performance characteristics apply to the N7610B Signal Studio for Wi-SUN application.

Definitions

Typical (typ): Represents characteristic performance, which 80% of the instruments manufactured will meet. This data is not warranted, does not include uncertainty, and is valid only at room temperature (approximately 25 ºC).

Characteristic Performance: Non-warranted value based on testing during development phase of this product.

The EVM measurements were made with an N9030A PXA signal analyzer with Option B1X (160 MHz bandwidth), using the 89601B VSA software with Option AYA for 2FSK and Option BHF for MR-OFDM modulation analysis.

The ACP measurement settings for 2FSK use the definition in section 18.1.5.6 of the IEEE 802.15.4g-2012 standard. The ACP values for MR-OFDM are measured on the first out-of-band channels (upper and lower), which are adjacent to the in-band channel. The bandwidths for both the in-band and out-of-band channels are set as the Channel Spacing values defined in Table 148 of the IEEE Standard 802.15.4g-2012, i.e., 1200 kHz, 800 kHz, 400 kHz and 200 kHz for OFDM Option 1, 2, 3 and 4 respectively.
