ware that supports the User Datagram Protocol (UDP IPv4, see Chapter A, "I/Q over
Ethernet (QSFP+) protocol" , on page 38).
Figure 2-2 shows the different frames that are exchanged between R&S SMM100A
and the PC.

Figure 2-2: Waveform data transfer from PC to R&S SMM100A
1 = PC as waveform data source
2 = Control frame: APPL command: restart ARB
3 = Control frame: End of waveform data transfer
4 = Data frames: Waveform data as UDP datagrams/frames
5 = Control frame: start of waveform data transfer
6 = Control frame: APPL commands: stop ARB, set waveform parameters (clock, length, etc.) in wave-
form tags/header
7 = R&S SMM100A as waveform data sink
8, 9 = Acknowledgement frames
Table 2-1 describes the corresponding sequence of frames sent between the PC to the
R&S SMM100A. The application control frames for sequence event 1 and sequence
event 6 are mandatory.
Table 2-1: Waveform data transfer: Frame sequences
Sequence Frame type Description Label 2-2
1 Control frame PC: Sends application control frames to stop ARB, set
waveform parameters (clock, length, etc.) as wave-
form tags or waveform header data.
R&S SMM100A: Restarts the ARB application.

3 Control frame PC: Defines the start of waveform data transfer. 5
4 Data frame PC: Transfers waveform data as UDP datagrams/
frames.
R&S SMM100A: Receives waveform data as UDP
datagrams/frames.
