07 | Keysight | E1968A GSM/GPRS/EGPRS Test Application - Technical Overview
Technical Specifications
These specifications apply to an E5515C mainframe with Option
002, or E5515E when used with the E1968A test application of
firmware revision A.09 or higher, or the E1987A test application of
firmware revision A.08 or higher. Depending on the exact con-
figuration, earlier E5515C and E5515B instruments may require
hardware upgrades to obtain certain features and capability. Fea-
tures which may require hardware upgrades include: EGPRS (all
capability), higher EGPRS multislot classes, spectrum monitor, RF
out only port, phase and amplitude versus time (PAvT), fast device
tune, and ORFS digital filter option.
CAUTION: Loading an application onto your E5515C/E test set
that is not compatible with your E5515C/E’s hardware revision
can cause your E5515C/E to lock-up. For information on appli-
cation/E5515C/E compatibility go to www.keysight.com/find/
E5515C and select the relevant link to E5515C/E Release Notes.
Always refer to this information before loading an application.
Supplemental characteristics are intended to provide additional
information useful in applying the instrument by giving typical,
but non-warranted performance parameters. These characteris-
tics are shown in italics and labeled as “typical,” or “supplemen-
tal,” and apply at +25 °C.
RF generator level accuracy is derived from 95th percentile
observations with 95 percent confidence (corresponds to an
expanded uncertainty with a 95 percent confidence (k=2)) at
ambient conditions, then qualified to include the environmental
effects of temperature and humidity.

OUT ONLY port on the 8960 (E5515C/E).
