5.2.1 DC power supply connection
To ensure high mobility and flexibility while using the R&S EDST300, it is equip-
ped with a DC power supply connector on the rear panel of the instrument.
For safety information, refer to "Connecting to power" on page 4.
For details, refer to Chapter 4.7, "Connecting to power" , on page 15.
5.2.2 SUPPRESS IN / OUT connector
The R&S EDST300 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
suppressor line" , on page 17).
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
EDST300. 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 EDST300 can provide various analog signals as output at the "ANA-
LOG 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 EDST300 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 SYNC1/2 OUT
If option R&S EDST-B6 is installed, two BNC connectors are provided to output
pulsed synchronization signals to a connected device. The signal voltage level is
5
V. The pulse period for the signal at the "SYNC1 OUT" connector is 135 Hz
