E-1
New Features on All Models
DIGITAL MOD – FILTER menu:
A new filter was added:
(FILTER...)
FILTER TYPE
GAUSS LINEAR linearized Gaussian filter for GSM_EDGE
(to GSM Specification 05.04, Change Request A010)
IEC/IEEE-bus command:
:SOUR:DM:FILT:TYPE LGA
GAUSS LINEAR
(old version)
linearized Gaussian filter for GSM_EDGE
(to GSM Specification older than 05.04)
IEC/IEEE-bus command:
:SOUR:DM:FILT:TYPE OLG
DIGITAL STD – WCDMA/3GPP menu:
OCNS CHANNELS was changed to ADD OCNS.
ADD OCNS
Simulation of orthogonal channel noise. This menu item is available only in the downlink
and if option SMIQB48 is installed. For more information refer to section 2.15.4.
Section 2.15.4 ADD OCNS:
Generation of orthogonal channel noise (OCNS) to TS 25.101
The OCNS scenario is defined as follows:

Parameters common to all OCNS channels:
Type:
DPCH
Symbol rate:
30 ksps
Pilot length:
8 bit
The powers of the OCNS channels are to be understood as relative powers only. In the test scenarios
defined by the standard, the OCNS channels are weighted so that a sum power of linear 1 (or 0 dB) is
obtained. This is done automatically in SMIQ.
