Preparing for Use

Unpacking and Checking the Instrument

Inspect the package for damage.
If the packaging material shows any signs of stress, notify the carrier who delivered the instrument.
Carefully unpack the instrument and the accessories.
Check the equipment for completeness. See section “Delivery contents” on page 9.
Check the equipment for damage.
If there is damage, or anything is missing, immediately contact the carrier as well as your distributor. Make sure not to discard the box and packing material.

Packing material
Retain the original packing material. If the instrument needs to be transported or shipped later, you can use the material to protect the control elements and connectors.

Delivery contents
The delivery package contains the following items:

R&S RTC1000 digital oscilloscope
R&S RT-ZP03 probe probes (2x)
Country-specific power cable
Printed “Getting Started” manual
Printed “Basic Safety Instructions” brochure

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.

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.

CAUTION

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.

NOTICE

Risk of instrument damage due to overheating
An insufficient airflow can cause the R&S RTC1000 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.

Starting the Instrument

Powering On
The R&S RTC1000 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, or 100 V to 120 V at 400 Hz
max. 25 W

CAUTION

Risk of injury
Connect the instrument only to an outlet that has a ground contact.
Do not use an isolating transformer to connect the instrument to the AC power supply.

Connect the power cable to the AC power connector on the rear panel of the R&S RTC1000.
Connect the power cable to the socket outlet.
Switch the main power switch at the rear of the instrument to position I.
The [ON/OFF] key lights up when the instrument is in standby mode. The key is located next to the upper right corner of the screen.

You can leave the main power switch on to preserve your last instrument settings.
To disconnect from power supply, power off the instrument.

Starting Up and Shutting Down

To start up the instrument

Make sure that the R&S RTC1000 is connected to the AC power supply and the main power switch on the rear panel is in position I.
Press the [ON/OFF] key. The key is located next to the upper right corner of the screen.
The instrument performs a system check and starts the firmware. If the previous session was terminated regularly, the oscilloscope uses the last settings.

Table 3-1: Colors of the [ON/OFF] key

Unlit	Instrument is on: firmware is working
Red	Standby: instrument is off, main power switch is on

Warm-up and prepare the instrument
Make sure that the instrument has been running and warming up before you start the self-alignment and the measurements. The minimum warm-up time is about 20 min.

To shut down the instrument to standby state

Press the [ON/OFF] key.
All current settings are saved, and the software shuts down. Now it is safe to power off the instrument.

Powering Off
Powering off is required only if the instrument must be disconnected from all power supplies.

If the instrument is running, press the [ON/OFF] key on the front panel to shut down the instrument.
Switch the main power switch at the rear of the instrument to position 0.
Disconnect the AC power cable from the AC power supply

NOTICE

Risk of losing data
If you switch off the running instrument using the rear panel switch or by disconnecting the power cord, the instrument loses its current settings.
Furthermore, program data can be lost.

Press the ON/OFF key first to shut down the application properly.

EMI Suppression

Electromagnetic interference (EMI) may affect the measurement results.

To suppress generated electromagnetic interference (EMI):

Use suitable shielded cables of high quality. For example, use double shielded RF and LAN cables.
Always terminate open cable ends.
Note the EMC classification in the data sheet.

Replacing the Fuse

The instrument is protected by a fuse. You can find it on the rear panel between the main power switch and AC power supply.

Type of fuse: Size 5×20 mm, 250V~, T2.5H (slow-blow), IEC60127-2/5

WARNING

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.

Pull the fuse holder out of its slot on the rear panel.
Exchange the fuse.
Insert the fuse holder carefully back in its slot until it latches.

Input Connectors

Input Connectors

BNC inputs (6, 7)
The R&S RTC1000 has two channel inputs (6) to connect the input signals. The external trigger input (7) 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.

WARNING

Risk of electrical shock – maximum input voltages
The maximum input voltage on channel inputs must not exceed 200 V (peak) and 150 V (RMS).

For the external trigger input, the maximum input voltage is 100 V (peak) and 70 V (RMS).

Transient overvoltages must not exceed 200 V (peak).

Voltages higher than 30 V (RMS) or 42 V (peak) or 60 V DC are regarded as hazardous 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.

CAUTION

Risk of injury and instrument damage
The instrument is not rated for any measurement category. When measuring in circuits with transient over voltages of category II, III or IV circuits, make sure that no such overvoltages reach the R&S RTC1000 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 200 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.

Logic probe (9)

The connector for logic channels can be used if the Mixed Signal Option R&S RTC-B1 is installed. The option provides a logical probe with 8 digital channels (D0 to D7).

The maximum input voltage is 40 V (peak) at 100 kΩ input impedance. The maximum input frequency for a signal with the minimum input voltage swing and medium hysteresis of 800 mV (Vpp) is 300 MHz.

NOTICE

Risk of instrument damage
Use the connector for the active logic probe exclusively for the logic probe R&S RT-ZL03, which is delivered with option R&S RTC-B1. Connecting other probe types can demolish the input.
