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.
