2.2 About ARB ethernet upload
Equipped with option R&S SMM-K507 ARB ethernet upload, the R&S SMM100A can
upload waveforms significantly faster to its ARB memory. Data rates of 10 Gbit/s and
40 Gbit/s at the QSFP+ connectors "HS Dig I/Q" allow much shorter waveform loading
times. These loading times can be up to 100 times shorter compared to waveform
upload via the USB or the other I/Q connectors "I/Q" and "Dig I/Q".
Test setup
Figure 2-1 shows a typical test setup including a personal computer (PC) as waveform
source and the R&S SMM100A that is processing the waveform I/Q data.

Waveform transfer and waveform upload
For waveform data transfer, the PC is equipped with an application that supports and
executes waveform data transmission. This application can be a driver or a client soft-
