04 | Keysight | E1968A GSM/GPRS/EGPRS Test Application - Technical Overview

Integrated GSM, GPRS, and EGPRS

Functionality

– Switch between GSM, GPRS, and EGPRS serving cells

– Switch between data and voice connections without losing

camp or attach

– Establish a voice or data connection after initial GPRS attach

– Supports Evolved EDGE functionality

– Supports EGPRS2-A signaling and test mode measurement

GSM functionality

Evolved EDGE Functionality

Downlink PDTCH

– Downlink dual carrier (DLDC) setup

– Supports RTTI mode

– Fast Ack/Non-Ack setup

– 16QAM/32QAM downlink setup

– 16QAM uplink setup

Call Processing Functionality

– GSM MS and BS origination

– GSM MS and BS release

– GPRS mobile-initiated attach and detach

– GPRS and EGPRS packet data transfers on uplink and

downlink

– E-EDGE and EGPRS2-A call setup

– Intra-cell channel assignments

– Inter-cell handovers between all bands

– Handover from W-CDMA to GSM (with E1987A test

application)

– 2-box handover from W-CDMA to GSM or GSM to GSM

– BA table with 16 settable neighbor cells

– External triggers provide a signal output each frame with

settable timeslot, bit, and option to include or exclude the

idle frame

BCH setup and parameters

– Settable downlink power, band, and channel number

– Settable maximum control channel power used by the MS for

access bursts of 0 to 31

– Settable maximum control channel power offset value for

DCS 1800 MHz band of 0 to 3

– Band indication of DCS or PCS

GSM TCH parameters

– Settable downlink in TCH power including power in unused

bursts, uplink band, channel number, and power level

– Channel modes of FR, EFR, and HR, plus HR subchannel of 0

or 1

– Settable uplink timeslot of 1 to 7

– Settable timing advance of 0 to 63

– Mobile loopback of off, type A, type B, or type C as defined in

ETSI 04.14 or 3GPP 44.014

– Downlink TCH speech types of none, echo, 300 Hz sine, 1

kHz sine, 3 kHz sine, or PRBS-9, PRBS-15, multi-tone, cus-

tom or real-time vocoder
