Specifications for
Vector Signal Generator R&S SMIQ
Valid from 7/2002
Specifications are guaranteed under the following conditions: 30 minutes warmup time at ambient temperature, specified environmental
conditions met, calibration cycle adhered to, and total calibration performed. Data designed „overrange“ are not guaranteed. Data without
tolerances: typical values. – In compliance with the 3GPP standard, chip rates are specified in Mcps (million chips per second), whereas
bit rates, symbol rates and sample rates are specified in kbps (thousand bits per second) or ksps (thousand symbols/samples per second).
Mcps, kbps and ksps are not SI units.

Internal or external via BURST GATE input/output (PAR DATA connec-
tor). The BURST GATE input triggers a power ramp (TTL levels). The
low/high transition starts the ramp function from blanking level to max-
imum level, the high/low transition from maximum level to blanking
level. With an internal power ramp, the connector serves as an output.

TS25.211 and TS25.213
Option R&S SMIQB45 WCDMA 3GPP is extended by the following functions:
Enhanced Channels
Channels of WCDMA system in R&S SMIQ that offer enhanced functionality compared with standard channels of option
R&S SMIQB45.
Can be used in downlink for max. four DPCHs and in uplink for one DPCCH and max. six DPDCHs.
All DPCHs or DPDCHs have the same symbol rate.
Enhanced functions at a glance:
• Sequences of up to 1022 frames
• Realtime BCH with incrementing SFN
• Data lists for data fields and TPC field
• External power control
• Channel coding
• Bit error insertion
• Block error insertion
• Orthogonal channel noise simulation (OCNS)
• Additional mobile stations
Sequences of up to 1022 frames generation of WCDMA signals with length of max. 256 frames
with four active enhanced channels and max. 1022 frames with
one active enhanced channel
Applications – continuous measurement of physical bit error rate (without chan-
nel coding) on code channel with PN9 data without wraparound problems
– use of user data (data lists) with externally processed long data
sequences for enhanced channels
Realtime BCH with incrementing SFN Generation of a realtime downlink BCH (coded P-CCPCH) with
incrementing system frame number (0 to 4094). BCH can be combined with all reference measurement channels (bit rate 12.2 kbps,
64 kbps, 144 kbps, 384 kbps) or AMR of 12.2 kbps bit rate.
Max. sequence length:
RMC 12.2 kbps 2044 frames
RMC 64 kbps 512 frames
RMC 144 kbps 512 frames
RMC 384 kbps 512 frames
AMR 12.2 kbps 2044 frames
Application – receiver and performance tests to TS25.101
– test of mobile synchronization to BS signal combined with:
continuous measurement of DTCH and DCCH bit and block error rate using PN9 data
Vector Signal Generator R&S SMIQ – Specifications 21
Data lists for data fields and TPC field For the enhanced channels, the data fields and the transmit power
control (TPC) field of the slots can be filled from data lists. This
allows the use of externally precoded data or the generation of
long power control profiles for the DUT.

Arbitrary waveform generator with option R&S SMIQB60
Waveform memory, interpolation
Output memory
Length of waveform
Note: The specified waveform length cannot be directly compared with the relevant data of conventional ARB generators.
In R&S SMIQB60, the oversampling needed for suppressing repetitive spectra by means of the analog filter is effected
automatically and in realtime by way of hardware interpolation, ie the stored waveform is not extended by the oversampling factor. For W-CDMA signals, for example, oversampling of only 1.62 is needed. This compares with a conventional
ARB with oversampling of 4, meaning that R&S SMIQB60 output memory capacity corresponds to 1.25 Msamples.

Operation with WinIQSIM™
WinIQSIM™ is a Windows software that allows a wide variety of I and Q baseband signals to be calculated on a PC
(see WinIQSIM™ data sheet PD 0757.6940). From version 3.30, the software supports downloading of waveforms into
R&S SMIQ and operation of option R&S SMIQB60 from a PC.
