2.2.1.1 Input Connectors
BNC inputs (4 and 5)
The R&S RTB2000 has two or four channel inputs (4) to connect the input signals. 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.
The input impedance of all BNC inputs is 1 MΩ.
Risk of electrical shock - maximum input voltages
The maximum input voltage on channel inputs must not exceed 400 V (peak) and
300 V (RMS).
For the external trigger input, the maximum input voltage is 400 V (peak) and
300 V (RMS).
Transient overvoltages must not exceed 400 V (peak).
Voltages higher than 30 V (RMS) or 42 V (peak) or 60 V DC are regarded as hazard-
ous contact voltages. When working with hazardous contact voltages, use appropriate
protective measures to preclude direct contact with the measurement setup:
●
Use only insulated voltage probes, test leads and adapters.
●
Do not touch voltages higher than 30 V (RMS) or 42 V (peak) or 60 V DC.
Risk of injury and instrument damage
The instrument is not rated for any measurement category. When measuring in circuits
with transient overvoltages of category II, III or IV circuits, make sure that no such
overvoltages reach the R&S RTB2000 input. Therefore, use only probes that comply
with DIN EN 61010-031. When measuring in category II, III or IV circuits, always insert
a probe that appropriately reduces the voltage so that no transient overvoltages higher
than 400 V (peak) are applied to the instrument. For detailed information, refer to the
documentation and safety information of the probe manufacturer.
Explanation: According to section AA.2.4 of EN 61010-2-030, measuring circuits with-
out any measurement category are intended for measurements on circuits which are
not directly connected to the mains.
