Assess Design Readiness with Greater Confidence

Keysight Technologies, Inc.’s E7523A and E7623A W-CDMA/HSPA+ test and lab application software run on the E7515A UXM wireless test set, providing the integrated capabilities you need to achieve greater confidence in your W-CDMA/HSPA+ UE or chipset design. Adding W-CDMA/HSPA+ test functionality to your existing UXM test set is a simple software-only upgrade.

The E7523A W-CDMA/HSPA+ test application (TA) software provides the tools you need to be confident about your device’s RF performance. The TA includes flexible receiver test, trusted X-Series transmitter measurement science, and basic network emulation. This enables you to set up defined conditions with varying frequencies, power, and modulation. It also allows you to measure to limits and determine the root cause of failures with reliable, repeatable results that can be automated and easily shared. Test from early designs to finished products — the UXM supports measurements with signaling or using test modes, making it easy to “just connect” and focus on RF validation.

The E7623A W-CDMA/HSPA+ lab application (LA) software provides both functional and RF test capabilities for overall device design validation. The LA includes the receiver and transmitter test functionality of the TA, plus IP data-based capabilities such as end-to-end data throughput, and advanced network emulation such as complex handover scenarios, RRC state transitions, and support for CPC and simultaneous services. This added functional test capability helps you verify connection continuity, data rate performance, concurrent application behavior, battery drain, and protocol messaging.

Ensure W-CDMA/HSPA+ Devices Achieve and Sustain Reliable End-to-End IP Data Throughput

The UXM’s built-in fading and noise, integrated applications server, and easy-to-use touch screen interface make it simple to validate your device’s true data performance.

With the touch of a finger, efficiently navigate UXM’s wealth of features and flexible configurations to investigate throughput issues and bottlenecks

With the E7623A W-CDMA/HSPA+ LA software, you can verify maximum downlink and uplink throughput for DC-HSDPA and DB-DC-HSDPA with stable, bi-directional data throughput for up to 42 Mbps downlink and 11.5 Mbps uplink. Ensure your device will operate as expected in a real-world environment with flexible independent fading and noise for each carrier.

Go Deeper in Functional Test by Emulating a Wide Range of Complex Network Operations

With the UXM’s lab application software, you can validate your device’s functional performance by emulating a wide range of complex network operations such as mobility, simultaneous services, and CPC. You can also characterize battery drain performance with flexible network and RRC state transition settings. The UXM’s flexible touchscreen provides a simple and intuitive interface that makes it easy access to a wealth of network parameters so you can thoroughly characterize your device’s functional behavior. With support for packet data connections, voice, SMS/MMS, compressed mode, and UE reporting, the UXM lets you quickly validate changes in design from RF to TCP with a comprehensive test of mobile functions right at your desk.

Verify LTE/W-CDMA inter-RAT mobility in a single test set with two built-in independent cells. Validate voice mobility with circuit-switched fallback (CSFB), redirect to LTE, and single radio voice call continuity (SRVCC). Quickly characterize LTE/W-CDMA inter-RAT performance with automatic negotiation of cell parameters. Easily analyze data through-put during packet-switched (PS) handovers and verify UE behavior during cell reselection scenarios.

Evaluate PS data performance using CPC statistics

Verify UE behavior when continuous packet connectivity (CPC) is active. Manually select or send HS-SCCH orders to set up or re-configure uplink DTX, downlink DRX, and HS-SCCH-less operation. Perform various call processing activities with CPC enabled, such as web browsing, video streaming, and file download. Characterize the resulting data performance with the UXM’s extensive CPC settings and statistics.

As you use the UXM’s lab application software to emulate various network operations (including those involving multiple UXMs connected in an array), you can log all of the associated protocol messaging for all cells in the UXM array — both LTE/LTE-A and W-CDMA/HSPA+. The Wireshark-based protocol logging and analysis software allows you to examine multi-cell, multi-format messaging in a single, time-aligned display.

Achieve Greater Confidence in RF Performance

Every UXM test and lab application software product includes the industry-proven X-Series measurement applications for consistent, repeatable transmitter testing. With the X-Series applications you can run measurements per the 3GPP 34.121 test specifica-tions, or use the full range of X-Series capabilities to explore beyond the specifications. The X-Series applications’ comprehensive test coverage, built-in context-sensitive help, and familiar user interface get you up and running quickly, with the flexibility required to check compliance and troubleshoot tough transmitter issues. The X-Series measurement applications closely follow the 3GPP standard, allowing you to stay on the leading edge of your design challenges.

With the UXM’s integrated fading, MIMO, and suite of built-in receiver measurements, you can characterize RF receiver performance under realistic and varying channel conditions, from one simple-to-use interface. You can also test from early designs to finished products since the UXM supports measurements with signaling or using test modes — making it easy to “just connect” and focus on RF validation.
