1.2.2 Notes on Screenshots
When describing the functions of the product, we use sample screenshots. These
screenshots are meant to illustrate as much as possible of the provided functions and
possible interdependencies between parameters. The shown values may not represent
realistic test situations.
The screenshots usually show a fully equipped product, that is: with all options installed. Thus, some functions shown in the screenshots may not be available in your particular product configuration.
1.2.3 Naming of Software Options
In this operating manual, we explicitly refer to options required for specific functions of
the digital standard.
The name of software options for signal generators vary in the name of the instrument,
but the option name is identical. Therefore we use in this manual the placeholder
R&S SMx/AMU.
Example:
Naming for an option of the vector signal generator R&S SMBV100A, e.g:
●
R&S SMx/AMU-K99, stands for R&S SMBV-K99
The particular software options available for the corresponding instruments are listed
on the back of the title page.

About the 1xEV-DO Options1xEV-DO Rev. A/Rev. B
2 About the 1xEV-DO Options
The R&S Signal Generator (options R&S SMx/AMU-K47/-K87) provides you with the
ability to generate signals in accordance with the standard CDMA2000 1xEV-DO (Evolution-Data Optimized), Rev. B. CDMA2000 1xEV-DO is the North American standard
for the third mobile radio generation (3G). CDMA2000 1xEV-DO is a high-speed
packet-switched transmission technique with forward peak data rates of 4.9152 Mbps
per carrier, designed and optimized for a data-centric broadband network.
The R&S Signal Generator simulates 1xEV-DO signal at the physical layer. In forward
link (downlink) mode the signal is generated in realtime. Parameter changes during
active signal output take effect immediately without signal interruption. In reverse link
(uplink) mode the signal is precalculated and played from the ARB memory. Parameter
changes result in a recalculation of the signal.
To playback a signal from a waveform file created by the simulation software
R&S WinIQSIM2, the corresponding R&S WinIQSIM2 digital standard option must be
installed.
The following list gives an overview of the main options provided by the R&S Signal
Generator for generating an 1xEV-DO signal in accordance with 3GGP2 C.S0024B.v3.0.
●
Generation of 1xEV-DO signals with a chip rate of 1.2288 Mcps
●
Independent configuration of up to 4 traffic channels or 4 access terminals
●
Support of physical layer subtypes 0, 1, 2 and 3
●
Support of multi-carrier operation with up to 16 simultaneous carriers
●
Operating modes "Traffic" and "Access" on the uplink
●
Simulation of up to 360 additional MAC users
●
Generation of standard compliant forward/downlink and reverse/uplink channel
types
●
Supports configuration of public data as defined in the standard, such as Long
Code Masks for I and Q channel, PreambleLength, DRCLength etc.
●
Filling the data files for data channels from all possible sources of the R&S Signal
Generator: pattern (all1, all0, user-defined up to 64 bits), PN data or data lists
●
Clipping for reducing the crest factor

About the 1xEV-DO Options1xEV-DO Rev. A/Rev. B
Traffic Scheduling Process
2.1 Traffic Scheduling Process
In the 1xEV-DO system, the Forward Link is govern by a time division multiple access
technique; access to Forward Link bandwidth by a user channel is governed by a
scheduling process. The schedule process determines who gets access to Forward
Link slots to carry user data.
The traffic scheduling process in this instrument follows a number of rules to schedule
which user's data is sent for each slot.
The rules are listed in order of priority, with the highest priority rules being listed first. In
the event that two rules contradict each other, the circumstances invoking the lower
priority rule must be altered to resolve the contradiction.
●
A channel with "State = Off" is never transmitted.
●
The first slot of the control channel packet is always transmitted at its specified offset at the start of the control channel cycle.
●
Once the first slot of a multiple slot packet is sent, the remaining slots are always
transmitted with the proper interlace (3 slots skipped after 1 slot sent).
●
Packets for a user can be transmitted on 1-4 interlaces (there are a total of 4 interlaces in the 1xEV-DO system). Packets on the different interlaces will be duplicates
of those sent on the other interlaces for a given user. The interleave factor user
interface parameter is used to control the number of interlaces used for each user.
●
Immediately after the transmission of the last slot of a multiple slot packet, a lockout period of three slots is created. No additional packets from the same source
may be scheduled before the three slot period expires.
●
A control channel packet has priority over all other traffic channels. This may
exclude transmission of user channels in advance of the control channel packet, if
the other channel would require a slot that the control channel packet would
require.
●
User1 traffic has priority over User2, User3, and User4 traffic.
●
User2 traffic has priority over User3 and User4 traffic.
●
User3 traffic has priority over User4 traffic.
●
If no traffic is scheduled for a slot, an idle slot will be transmitted.

3.3 Multi Carrier Configuration Settings
Multi Carrier Configuration requires option R&S SMx/AMU-K87
In multi carrier mode, up to 16 modulated carriers can be generated with one baseband. Each carrier’s center frequency is input via it’s "CDMA Channel Number" or by
directly entering the RF "Center Frequency / MHz". The carriers can be activated or
deactivated separately.

For multiple slot packets, a value of zero will cause the next packet transmission to
start three slots after the end of the previous packet. The three slot delay is identical to
the interleaving delay between slots for multiple slot packets. The offset value is
attached to the end of the preceding packet.
Note: An offset value of zero with a rate change from a single slot packet to multiple
slot packets will cause the first slot of the multiple slot packets to be transmitted in the
slot immediately following the single slot packet.

A sequence of Up power control bits are sent followed by an equal

terminal to ramp its power from one extreme to another. The number
of power control bits in each direction is specified by the "RPC Range

Range mode is specified, the sequence will be restarted.
The Range mode starts with the first Up bit and ends with the last
Down bit.
The length of the mode is two times the RPC Range Count.
A user-defined sequence of RPC bits is sent. The mode starts with
the bit defined in the first (0) zone, and ends with the last bit of the
