(TACAN ARB). The pulse period for the signal at the "SYNC2 OUT" connector is
15
Hz (TACAN MRB).
5.2.5 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
EDST300. 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
EDST300 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.
5.2.6 USB
The rear panel provides additional female USB (USB-A) connectors to connect a
memory device or power sensor.
The connectors are standard USB 3.0 ports with a maximum transmission rate of
40
Mbit/s.
For further USB connectors, see also Chapter 5.1.4.2, "USB interface" ,
on page 23.
5.2.7 REF 10 MHz IN/OUT
The "REF 10 MHz IN/OUT" connector can provide an external reference signal to
the R&S
EDST300, or from the R&S EDST300 to a connected device. In either
case, the reference signal is at 10 MHz, with a power level of 1 V
eff
. The connec-
tor is a 50
Ω
BNC socket.
Configure whether the connector is used for input or output in the general instru-
ment settings.
