2.1.2 Positioning the Instrument
The instrument is designed for use under laboratory conditions. It can be used in
standalone operation on a bench top or can be installed in a rack.
For standalone operation, place the instrument on a horizontal bench with even, flat
surface. The instrument can be used in horizontal position, or with the support feet on
the bottom extended.

Getting Started
Preparing for Use
The instrument can be installed in a 19" rack mount using a rack mount kit. The order
number of the rack mount kit is given in the data sheet. The installation instructions are
part of the rack mount kit.
Risk of injury if feet are folded out
The feet can fold in if they are not folded out completely or if the instrument is shifted.
This can cause damage or injury.
●
Fold the feet completely in or out to ensure stability of the instrument. Never shift
the instrument when the feet are folded out.
●
When the feet are folded out, do not work under the instrument or place anything
underneath.
●
The feet can break if they are overloaded. The overall load on the folded-out feet
must not exceed 200 N.

Risk of instrument damage due to overheating
An insufficient airflow can cause the R&S RTA4000 to overheat, which can impair the
measurement results, disturb the operation, and even cause damage.
●
Ensure that all fan openings are unobstructed and that the airflow perforations are
unimpeded. The minimum distance to a wall is 10 cm.
●
When placing several instruments side by side, keep a minimum distance of 20 cm
between the instruments. Ensure that the instruments do not draw in the preheated
air from their neighbors.
●
When mounting the instrument in a rack, observe the instructions of the rack manufacturer to ensure sufficient airflow and avoid overheating.
2.1.3 Starting the Instrument
The R&S RTA4000 can be used with different AC power voltages and adapts itself
automatically to it.
The nominal ranges are:
●
100 V to 240 V AC at 50 Hz to 60 Hz
●
1.6 A to 0.7 A

Risk of electric shock
The fuse is part of the main power supply. Therefore, handling the fuse while power is
on can lead to electric shock. Before opening the fuse holder, make sure that the
instrument is switched off and disconnected from all power supplies.
Always use fuses supplied by Rohde & Schwarz as spare parts, or fuses of the same
type and rating.
1. Pull the fuse holder out of its slot on the rear panel.
2. Exchange the fuse.
3. Insert the fuse holder carefully back in its slot until it latches.

2.2.1.1 Input Connectors
BNC inputs (4 and 5)
The R&S RTA4000 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.

Instrument Tour
For channel connectors, the input impedance is selectable, the values are 50 Ω and
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) at 1 MΩ input impedance
●
30 V (peak) and 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 MΩ input impedance.
Transient overvoltages must not exceed 400 V (peak).
For further specifications, refer to the data sheet.
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 RTA4000 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 without any measurement category are intended for measurements on circuits which are
not directly connected to the mains.
