06 | Keysight | TD-SCDMA_GSM Fast Switch Test Application - Technical Overview

TD-SCDMA mode (test and active cell)

Call connection types

AMR voice:

Standard voice call with audio loopback for a quick check of voice functionality for 12.2 k

rate; also many more AMR rates, such as 4.75, 5.15, 5.9, 6.7, 7.4, 7.95, 10.2, and 12.2 k

ââ UE and BS origination 12.2 k

ââ UE and BS release

TDD test mode:

TDD test mode allows you to test the parametric performance of your UEâs transmitter

and receiver without call processing. In TDD test mode, the test set does not send sig-

naling information on the downlink. Rather, it continuously generates a downlink signal

and searches for a corresponding uplink signal. The UE must synchronize to the downlink

signal and send and appropriate uplink signal, which the test set uses to measure the

UEâs transmitter and receiver performance. Any changes to the UE configuration must be

accomplished by directly sending commands to the UE from a system controller through

a proprietary digital interface

RB test mode:

Fast conformance test calls with significant configuration control and testing capabilities

ââ BS origination and release

ââ Support symmetrical RMCs at 12.2 rates. The symmetrical RMC are typcally used for

transmitter testing and receiver testing user BER (via loopback type 1) or BLER

(via loopback type 2)

Inter-system handover:

Dual-mode functionality is required for most TD-SCDMA phones, as GSM is an integral

part in the majority of devices shipping today. Inter-system handovers provide a means

to validate dual-mode performance at your desk instead of roaming on a real network.

Together with the E7515A UXM one box tester, the 8960 supports handover function-

alities such as CSFB, RRC release with redirection between TD-SCDMA and TD-LTE

networks

ââ Blind handovers from TD-SCDMA to GSM

ââ Configurable landing GSM cell

ââ Test control to GSM voice

ââ TD-SCDMA AMR voice to GSM voice

ââ RRC redirect from TD-LTE to TD-SCDMA

ââ RRC redirect from TD-SCDMA to TD-LTE

ââ CSFB from TD-LTE to TD-SCDMA

1.â Customer-installed instrument must have required options and firmware/software for system to function properly.

2.â For battery emulation for UE without battery or/and to automate UE power cycling.

3.â Extra for convenience use to avoid frequent change of SIM within multiple UE devices.
