LAN
The LAN interface can be used to connect the R&S
ESRP to a local network for
remote control, printouts and data transfer. The assignment of the RJ-45 connec-
tor supports twisted-pair category 5 UTP/STP cables in a star configuration (UTP
stands for
unshielded twisted pair
, and STP for

4.2.4
Ext Trigger / Gate In
The female connector for external trigger or gate input is used to control the mea-
surement by means of an external signal. The voltage levels can range from 0.5
to 3.5
V. The default value is 1.4
V. The typical input impedance is 10
kΩ.

Ref In
As a reference signal, you can either use the internal reference, or connect an
external one. The setup menu is used to switch between the internal and an
external reference. The REF IN female connector is used as an input for a
