1 PPS REF IN
This BNC jack is used as input for the 1PPS (1 pulse per second) reference pulse. The
1PPS reference pulse input of the R&S
DVMS is used for measuring the network delay
in DVB
‑
T distribution networks. Use a signal derived from an external GPS receiver
that provides short pulses at exactly 1
second distance. This input is activated, if one of
the SFN synchronization monitoring subparameters "SFN Sync Network Delay" is acti-
vated.
For details, refer to the user manual or help system.
3.2.4
DVI-D
The DVI
‑
D socket provides the monitor output signal of the built-in computer. Use a
computer monitor that provides a resolution of 1024x768 pixels or higher.
You can use a DVI
‑
I cable for connecting R&S
DVMS and display, but the analog video
interface (pins C1 to C4) is not provided by the R&S
DVMS.
