R&S®SMBVB-K47/-K87
1 Welcome to the 1xEV-DO digital standard
The R&S SMBV100B-K47/-K87 is a firmware application that adds functionality to generate signals in accordance to the CDMA2000® 1xEV-DO (Evolution-Data Optimized),
Rev. A and 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 SMBV100B simulates 1xEV-DO signal at the physical layer. In forward link
(downlink) mode, the signal is generated in real time. 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.
The following list gives an overview of the main feature provided by the
R&S SMBV100B for generating an 1xEV-DO signal in accordance with 3GGP2
C.S0024-B.v3.0.
●
Generation of 1xEV-DO signals with a chip rate of 1.2288 Mcps
●
Independent configuration of up to four traffic channels or four 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, Preamble Length, DRCLength.
●
Filling the data files for data channels from the following standard sources: pattern
(all1, all0, user-defined up to 64 bits), PN data or data lists
●
Clipping for reducing the crest factor

2.3 Traffic scheduling process
In the 1xEV-DO system, the Forward Link is governed 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 (three slots skipped after one slot sent).
●
Packets for a user can be transmitted on 1 to 4 interlaces (there are a total of 4
interlaces in the 1xEV-DO system). Packets on the different interlaces are duplicates of the packets 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
can be scheduled before the three slot period expires.
●
A control channel packet has priority over all other traffic channels. This excludes
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 is transmitted.

Trigger Source
The following sources of the trigger signal are available:
●

The trigger event is executed manually by the "Execute Trigger".
●
"External Global Trigger"
The trigger event is the active edge of an external trigger signal provided and configured at the User x connectors.
●
"Baseband Sync In"
In primary-secondary instrument mode, secondary instruments are triggered by the
active edge of the synchronization signal.

Sync. Output to External Trigger/Sync. Output to Trigger
Enables signal output synchronous to the trigger event.
●
"On"
Corresponds to the default state of this parameter.
The signal calculation starts simultaneously with the trigger event. Because of the
processing time of the instrument, the first samples are cut off and no signal is output. After elapsing of the internal processing time, the output signal is synchronous
to the trigger event.

●
"Off"
The signal output begins after elapsing of the processing time. Signal output starts
with sample 0. The complete signal is output.
This mode is recommended for triggering of short signal sequences. Short sequences are sequences with signal duration comparable with the processing time of the
instrument.

Routing and enabling a marker
The provided marker signals are not dedicated to a particular connector. They can be
mapped to one or more User x connectors.
To route and enable a marker signal, perform the following general steps:
●
Define the shape of the generated marker, i.e. select the "Marker > Mode".
●
Define the connector where the selected signal is provided.
Use the Global connectors settings.

A marker signal is generated at the start of each slot (every 1.67 ms).
A marker signal is generated every 26.67 ms (PN Sequence Period).
A marker signal is generated every 2 seconds.
(For reverse link mode)
A marker signal is generated at the beginning of every Arbitrary

marker signal is generated regardless of whether an ARB component
is used.
A regular marker signal that is defined by an On/Off ratio is generated. A period lasts one ON and OFF cycle.

Common
Comprises the common traffic channel settings:
State (User) ← Common
Enables or disables the selected user.
If the user is enabled, the proper "MAC Index" is placed within the MAC channel and
packets can be sent to the user. If disabled, the "MAC Index" is not present within the
MAC channel and packets cannot be sent to the user.
Note: Disabling the state of a user during a transfer aborts all transfers to the user.

23User Manual 1178.8094.02 ─ 06
R&S®SMBVB-K47/-K87
If "Infinite" is enabled, there is no limit to the number of packets sent to the user.

specified.
Remote command:
[:SOURce<hw>]:BB:EVDO:USER<st>:PACKet:INFinite on page 89
Number of Packets to Send - Value ← Common
Sets the number of packets to send to the selected user.
The number of packets to be sent depends on whether the parameter "Infinite" is
enabled or disabled. If "Infinite" is enabled, there is no limit to the number of packets
sent to the user.
If "Infinite" is disabled and a value is specified while packets are being sent, the new
count value is used at the end of transmission of the current packet. If a value of zero
is specified, the transmission to the user is stopped at the end of the current packet.

Packet Start Offset ← Common
Sets the minimum number of slots between the end of one packet and the beginning of
the next.
For single slot packets, a value of zero will cause the next packet to be sent in the
immediate next slot (subject to scheduling).
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.
24User Manual 1178.8094.02 ─ 06
R&S®SMBVB-K47/-K87
Note: An offset value of zero with a rate change from a single slot packet to multiple
slot packets causes the first slot of the multiple slot packets to be transmitted in the slot
immediately following the single slot packet.
See Chapter 2.3, "Traffic scheduling process", on page 11 for an explanation on how
the control and traffic channels are transmitted over time.

Rate Index ← Common
Sets an index into the table of rates and slot counts.
Note: Selected rate becomes effective at the beginning of the next packet transmitted
to the selected user.
For physical layer 0&1, the parameter "Rate Index" alone automatically set the packet
size, data rate and the slot count for the packets sent to the selected user. Parameters
"Packet Size", "Data Rate" and "Slot Count" are read-only.
