Input connectors
BNC inputs (4 and 5)
The R&S
RTA4000 has two or four channel inputs (4) to connect the input sig-
nals. The external trigger input (5) is used to control the measurement by an
external signal. The trigger level can be set from -5
V to 5
V.
For channel connectors, the input impedance is selectable, the values are 50
Ω
and 1
M
Ω
.
The maximum input voltage is 400
V
(peak), 300
V
(RMS) at 1 MΩ input impe-
dance and 30
V
(peak), 5
V
(RMS) at 50 Ω input impedance.
For the
external trigger input
, the maximum input voltage is 400
V
(peak) and
300
V
(RMS) at 1
M
Ω
input impedance.
Transient overvoltages must not exceed 400
V
(peak).
