SUPPRESS IN / OUT connector
The R&S
EDS300 allows for a suppressor line signal to be input or output via the
BNC "SUPPRESS IN / OUT" connector (see
Chapter 4.8.2, "Connecting a sup-
The (digital) voltage levels for the input can range from 8
V to 30
V (when active).
The (digital) voltage levels for the output depend on the power supply of the
R&S
EDS300. The power supply ranges from 20
V to 28
V.
With an internal battery, the output power supply range is 24
V
±
5
%.
The output voltage is the supplied voltage minus approx. 1
V.
In both cases, the impedance is 30
kΩ.
5.2.3
ANALOG IN / ANALOG OUT connectors
The R&S
EDS300 can provide various analog signals as output at the "ANALOG
OUT" BNC connector. The signal is output with a peak power level of 4
V and an
impedance of 50
Ω
.
Configure which signal to output in the general instrument settings.
The R&S
EDS300 can also analyze analog baseband signals from another
device via the "ANALOG IN" BNC connector. Input the signal with a peak power
level of 1
V and an impedance of 50
Ω
.
5.2.4
TRIGGER INPUT / OUTPUT
Use the female BNC "TRIGGER INPUT" connector to input an external trigger.
An external trigger, for example from the DME transmission system, can control
the measurement on the R&S
EDS300. The (digital) voltage levels can range
from 3.3
V to 33
V. The input impedance is 100
kΩ.
Use the female BNC "TRIGGER OUTPUT" connector to provide a trigger signal
from the R&S
EDS300 to another connected device, such as the DME transmis-
sion system. The trigger can be a pulse, ARB, or MRB signal, for example. The
(digital) output signal is TTL compatible (0
V / 5
V). The output impedance is
50
Ω.
Control the trigger signal in the measurement settings.
