4.2.1 How to monitor external IP input data
The R&S SMCV100B receives external IP input data as described in Chapter 4.1.1,
"How to apply an external IP input signal" , on page 36.
► Select "Input Signal > Info"
The "Info" side tab displays physical properties of the input IP stream data.
The standard packet length is 188 byte. The maximum useful data rate is specified by
the broadcast standard.
The measured data rate is lower and depends on the TS source settings. The useful
data rate is lower than the measured data rate due to null packets present in the trans-
port stream.
If "Stuffing > On", the useful data rate can be lower than the maximum useful data rate.
