4.1.1

How to Apply an External IP Input Signal

To connect the R&S

SMCV100B to local IP data network

1. Connect the IP source to the "IP Data" connector of the R&S

SMCV100B.

See chapter "Connecting to IP Data Interface" in the R&S

SMCV100B Getting Star-

ted user manual.

2. Select "Input Signal > General > Source > External".

3. Select "Input Signal > General > Input > IP".

4. In the "IP Channel x" side tab, click "Local IP Data Network".

By default, the R&S

SMCV100B assigns the IP address automatically using

DHCP

("Address Mode > Auto (DHCP)").

5. If "Network Status > Disconnected", try "Restart Network".
