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.

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.

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.

Provided are the following settings for configuring the clipping settings:
Clipping State
(For reverse link mode only)
Switches baseband clipping on and off.
Baseband clipping is a simple and effective way of reducing the crest factor of the sig-
nal. Since clipping is done before to filtering, the procedure does not influence the
spectrum. The EVM however increases.
1xEV-DO signals can have high crest factors particularly with many channels and long
sequences.
