E6706G Functionality Overview (continued)
Release A test support
The E6706G supports testing of the 1xEV-DO Release A physical 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. The E6706G supports all of the new forward traffic channel configurations
and enables accurate PER testing under realistic conditions using the 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 conducted spurious emissions.
Release B test support
The E6706G supports testing of the 1xEV-DO Release B physical subtype 3 air interface
using the multi-carrier test application protocol. Release B allows user traffic to
flow over more than one carrier, which significantly improves data rates. Up to three
E5515C/E instruments with the E6706G application (one per carrier) can be synchronized
together to perform Release B multi-carrier testing, or one box can be used for multiple
carriers in factory test mode only. Using the multi-carrier test application protocol, the
8960 Series 10 test solution supports Tx measurements including waveform quality and
frequency accuracy, maximum RF output power, and conducted spurious emissions.
Supported Rx measurements include demodulation of forward traffic channel in AWGN,
receiver sensitivity and dynamic range.
Hybrid mode
When combined with another E5515C/E running the E6702G cdma2000^® lab
application, the E6706G 1xEV-DO lab application supports cdma2000/1xEV-DO hybrid
mode operation. The built-in multi-unit synchronization capability allows the two units
to be synchronized on CDMA system time to allow for hybrid mode call processing and
functional test.
Mobile IP
Basic mobile IP support has been added to the E6706G application that enables the
AT to pass mobile IP negotiation. Complete mobile IP and data session handoff tests
require the addition of the Software Concepts Inc MOB-IP-SIM. Together, the E6706G,
E5515C/E, and the MOB-IP-SIM provide a powerful solution for verifying the AT’s mobile
IP protocol behaviors.
Fading tests
Option 004 adds a rear panel digital bus that enables fading when used with Keysight’s
N5106A PXB baseband generator and channel emulator. This solution provides receiver
fading tests with unprecedented accuracy and repeatability at a very attractive price
point. Baseband I/Q data from the E5515C/E is sent via the digital bus to the PXB, where
real-time fading is applied based on user-selected fading profiles. After digital fading,
AWGN can be digitally added to the waveform. The resulting waveform is then returned
to the test set via the digital bus for modulation. This solution eliminates almost all
associated calibrations and provides consistent repeatability.
