Technical Overviews

Technical Overview

Introduction

Accelerate high data rate testing—achieve greater confidence in your 1xEV-DO wireless access terminals The Keysight Technologies, Inc. 8960 Series 10 (E5515C/E) wireless communications test set, used with the Keysight E1966A 1xEV-DO test application is the first complete, one-box solution for testing all of the 1xEV-DO parametric configurations, while providing physical channel testing at the highest data rates. The E1966A is designed for manufacturing, as well as developers and designers of leading-edge 1xEV-DO wireless access terminals (ATs).

Key Features

- Supports 1xEV-DO Release 0 FTAP/RTAP, and optionally 1xEV-DO Release A FETAP/RETAP (Option 102) and Release B FMCTAP/RMCTAP (Option 103) call processing for accurate physical layer performance qualification

- Supports new forward link packet configurations (Option 104) including those using 64QAM that boost the potential data throughput from 3.1 up to 4.9 Mbps with one box or from 9.3 to 14.7 Mbps with three boxes over FMCTAP/RMCTAP

- Supports Release B multi-carrier physical layer test with one box in IS-856 test mode

- Reduces the risk of returns and recalls by testing packet error rate at all QPSK, 8PSK, 16QAM, and 64QAM forward link modulation modes supported in the 1xEV-DO Release 0, Release A, and Release B standards. Verifies new reverse link modulation formats including 8PSK supported in the 1xEV-DO Release A standard (Option 102)

- Supports all commercialized bands—0 (including Band subclass 4 for China Telecom), 1, 3, 4, 5, 6, 7, 10, 11, 12, 14, 15, 18, and 19

- Single channel GPS source simulates one satellite for calibration of UE’s built-in GPS receiver (Option E1999A-206)

- IS-856 test mode allows receiver testing without call processing

- E1987A fast switch test application enables rapid switching between the E1966A 1xEV-DO test application and the E1962B cdma2000® test application for dual mode phone test

- Options 405, 406, and 407 offer fading, multi-unit synchronization, and protocol logging features for mobile design and verification

E1966A Functionality Overview

Flexible network emulation for physical layer test

The E1966A 1xEV-DO test application supports flexible call processing for physical layer testing of 1xEV-DO ATs. Establishing sessions with the test set is completely automatic once the test set is configured with the correct frequency band, channel, and sector ID. The test set automatically handles random ATI requests from access terminals, UATI assignment, and session negotiation.

Once a session is established, test connections are initiated by a single connect command. When connected, powerful active, closed-loop power control can be used to manipulate the ATs as required for testing. Tests across multiple channels and frequency bands are fast and simple using the one-button handoff commands.

Standardized, call processing-based test mode connections

The E1966A supports physical layer testing through the standardized FTAP/RTAP over-the-air protocols (forward and reverse test application protocols). FTAP allows accurate receiver packet error rate measurements by eliminating the dynamic behaviors of the 1xEV-DO system.

RTAP provides control of the ATs’ reverse link enabling accurate reverse link measurements. RTAP allows such measurements as channel power, waveform quality, code domain power, and Tx spurious emissions.

Option 102 – 1xEV-DO Release A and B test support

The E1966A Option 102 supports testing of the 1xEV-DO Release A physical layer subtype 2 air interface using the enhanced test application protocol. Call processing with this new air interface is simple and easy using one-button commands—just like it is with the existing Release 0 functionality.

Option 102 adds support for all of the new forward traffic channel configurations and enables accurate PER testing under realistic conditions using the new FETAP protocol (forward enhanced test application protocol).

Using the new RETAP protocol (reverse enhanced test application protocol), all of the new subtype 2 reverse channel packet sizes and modulation types are easily tested for such parameters as power, waveform quality, code domain power, and Tx spurious emissions.

The option also supports testing of the new 1xEV-DO Release B physical layer subtype 3 air interface using the multi-carrier test application protocol on signal carrier.

Option 103 – 1xEV-DO multi-carrier test support

The E1966A Option 103 supports testing of the 1xEV-DO Release B physical subtype 3 air interface that includes multiple carriers using the new multi-carrier test application protocol. Up to three test sets can be interconnected via LAN and clock signals, to generate and analyze devices that support multi-carrier operation.

Call processing with this air interface is simple and easy using one button commands from the test set designated as the multi-carrier master unit—the same as it is with the existing Release 0/A functionality.

The multi-carrier master controls all main call processing functions and coordinates control with up to two other E5515C/E units designated as auxiliary units. As test standards define all multi-carrier tests to be performed on a per carrier basis, each test set makes independent measurements on each carrier.

Option 103 supports all defined FMCTAP and RMCTAP multi-carrier test cases for: waveform quality and frequency accuracy, maximum RF output power, conducted spurious emissions, forward traffic channel performance in AWGN, sensitivity and dynamic range and with an external signal generator, and single tone desensitization.
