E1969A TD-SCDMA_GSM Fast Switch Test Application

Technical Overviews

Technical Overview

Achieve more with the Keysight Technologies 8960 Series 10 (E5515C/E) platform and TD-SCDMA_GSM fast switch test application.

With the E1969A TD-SCDMA_GSM fast switch test application, the 8960 Series 10 (E5515C/E) test set covers TD-SCDMA user equipment (UE) test based on 3GPP standards.

On a single hardware platform, the E5515C/E, all 2G and 3G formats are supported with corresponding licenses: GSM/GPRS/EGPRS, W-CDMA/HSDPA/HSUPA, HSPA+, TD-SCDMA/TD-HSPA, cdma2000®, 1xEV-DO Rev A/Rev B. 

The E1968A GSM/GPRS/EGPRS test application is bundled together with TD-SCDMA/ TD-HSPA options (E1969A-101, E1969A-201, E1969A-403, E1969A-413, E1969A-407, E1969A-408, E1969A-502, and E1969A-503) in the E1969A to meet dual-mode requirements on all TD-SCDMA/TD-HSPA devices. 

E1969A-101 is designed to be used under non-signaling mode without an integrated TD-SCDMA protocol stack, while E1969A-201 supports signaling mode. E1969A-403 and E1969A-413 support the TD-HSPA data throughput testing in radio bearer (RB) test mode. 

E1969A-407 allows you to enable protocol decoding functionality. Wireless protocol advisor software supplies messaging for the mobile and network from MAC layer all the way to IP.

Triggering and filtering functionality lets you set up troublesome scenarios, such as intermittent failures. That means you can begin the scenario on Friday and come back Monday morning to a bounded and focused protocol log of exactly what happened surrounding the particular issue. 

Unlike other technologies supported on the 8960 Series 10, TD-SCDMA uses a test application instead of a lab application. The E1969A test application, which includes typical lab application functionality, is accessed using feature options.

Combining feature options with the test application gives you the quickest access to the latest capabilities and provides a flexible way to tailor the solution to your exact needs. 

The TD-SCDMA real-time Vocoder E1969A-408 is another key feature for 8960 TD-SCDMA capability. It includes a real time encoder for downlink audio test and decoder for the uplink test.

Together with the external audio generator and analyzer, the 8960 can perform the phone audio functional test at a phone production or QA station; together with artificial ear and mouth, the 8960 can do the acoustic test as defined in 3GPP TS 26.131 and TS 26.132. 

With the E1959A-501 inter-RAT with TD-LTE and E1969A-502 packet data service, the previous lab application functionality is available in the E1969A test application.

This gives developers the only instrument available that provides a systematic approach to root-cause analysis of high throughput issues in the mobile protocol stack, from decoded L1 to IP layer and inter-RAT. 

The newly-released feature option, E1969A-503, allows the 8960 to verify a phone’s performance with voice and data simultaneous service. It supports different simultaneous services configurations such as AMR 12.2 k with packet data 384 k/384 k, or HSUPA/ HSDPA, and different user scenarios from either data or voice connection to a simultaneous service (voice + data) connection. 

Reach high-volume production goals by moving prototypes quickly into production with this test solution’s fast and repeatable measurements, accurate characterization, and ease of programming. Realize rapid deployment and lower costs by just upgrading software on your existing 8960 Series 10. 

Key Capabilities

- Test TD-HSPA devices (HS-DSCH Categories 1-15 and E-DCH Categories 1-6) as defined in 3GPP TS 34.122

- Switch between TD-HSPA subtest conditions while on an active connection

- TD-SCDMA–LTE inter-RAT handovers when coupled with the Keysight Technologies, Inc. E7515A UXM wireless communications test set for LTE

- TD-SCDMA real-time downlink source

- AMR voice and echo

- FM and GPS receiver calibration in one box

- TD-SCDMA to GSM system handover

- TD-SCDMA real time Vocoder

- TD-SCDMA voice and data simultaneous services

With support for voice, short message service (SMS), packet data call connections, and protocol decoding, design changes in anything from RF to TCP can be quickly validated with a complete regression test of mobile functions right at your desk—helping you get your job done faster. 

Technical Specifications

These specifications apply to an E5515C mainframe with Option 003, or E5515E when used with the latest E1969A test application. Specifications in this document focus on TD-SCDMA-related parts of E1969A (options E1969A-101 and -201). For GSM/GPRS/EGPRS-related specifications, refer to Keysight E1968A GSM/GPRS/EGPRS Test Application, Technical Overview (5990-4520EN). 

Specifications describe the test set’s warranted performance and are valid for the unit’s operation within the stated environmental ranges unless otherwise noted. All specifications are valid after a 30-minute warm-up period of continuous operation. 

Supplemental characteristics are intended to provide typical, but non-warranted, performance parameters that may be useful in applying the instrument. These characteristics are shown in italics and labeled as “typical”. All units shipped from the factory meet these typical numbers at +25 °C ambient temperature without including measurement uncertainty.
