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

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
