R&S SMR Putting into Operation
1 Putting into Operation
his chapter contains all information about putting into operation (unpacking, connection to AC supply,
T
switching on and off), functional testing and installation of the instrument, preset settings and views of
the front and rear panel showing the controls and connectors needed for operation.
General Instructions
Before putting the SMR into operation, please make sure that
• the covers of the casing are put on and screwed,
• the ventilation openings are free,
• no signal voltage levels exceeding the permissible limits are applied at the inputs,
• the outputs of the instrument are not overloaded or connected incorrectly.
If these points are not observed, the instrument might be damaged.
Unpacking the Instrument
Take the instrument out of the shipping box and check whether the
items listed in the packing list and in the lists of accessories are all
included.
Remove the two protective caps from the front and rear of the SMR
remove protective cabs
Should the instrument be damaged, immediately notify the forwarder who shipped the instrument to you
and keep the box and packing material.
For further transport or shipment of the SMR the original packing should also be used. It is
recommended to keep at least the two protective caps for front and rear side in order to prevent
damage to the controls and connectors.
and carefully check the instrument for damage.
Setting up the Instrument
For applications in the laboratory or on a work bench, it is recommended that the support feet on the
bottom of the instrument be extended. For the LCD display, this provides the optimum viewing angle
which typically ranges from perpendicular to the display front to approximately 30° below.
Warning
The feet must be fully folded in or out. Only in this way can the stability of SML be
guaranteed and reliable operation be ensured. With the feet out, the weight of other
units put onto SML must not exceed 30 kg. The units must be secured against
slipping (eg by locking the feet of the unit at the top side of the enclosure).
When shifting the unit with the feet out, the feet might collapse and fold in. To avoid
injuries, the unit must therefore not be shifted with the feet out.

Putting into Operation R&S SMR
Supply Voltage
The SMR can be operated at a.c. systems from 100 to 120 V and 200 to 240 V at system frequencies
from 50 to 60 Hz. The power supply socket is situated at the rear of the instrument. The instrument
automatically sets itself to the voltage applied within the permissible voltage ranges. It is not necessary
to set the instrument to a certain supply voltage.
How to Ensure EMC
In order to avoid electromagnetic interference, the instrument may only be operated when it is closed
and with all shielding covers fitted. Only appropriate shielded signal and control cables may be used.
Power Fuses
The SMR is protected against short circuits by means of two fuses according to nameplate of the power
supply. The fuses are situated in the draw-out fuse holder which is inserted close to the power supply
socket (see below).

Initial Status
Upon switching on, the instrument automatically assumes the status which was set when it was
switched off.
If the instrument need not to be operated from the initial status any further, a defined default status
should be established by pressing the [PRESET] key prior to further settings.
Frequency accuracy after switching on when the oven-controlled reference oscillator is fitted
(option SMR-B1)
Switch on: Press switch.
The instrument is ready for operation.
Switch off: Release switch.
The reference oscillator needs some minutes of warm-up time to reach its nominal frequency. During
this period of time, the output frequency does not yet reach its final value either. In the status line in the
header field of the display the message "OVEN COLD" is displayed for this time.
1134.9108.12 E-1 1.2
R&S SMR Putting into Operation
RAM With Battery Back-Up
The SMR has a static read-write memory (CMOS-RAM) with battery back-up, in which 50 different
complete settings of the instrument can be stored (cf. Chapter 3, section "Storing and Calling of
Instrument Settings"). In addition, all data and/or lists the user enters himself, such as for list mode,
memory sequence, and user correction of the level, are stored in the RAM. Further, all data of the
calibrations running within the instrument in the SMR are stored in the RAM (cf. Chapter 4, section
"Calibration" and Service Manual Instrument). A lithium battery with a service life of approx. 5 years
serves to supply the RAM with power. When the battery is discharged, the data stored will be lost.
Exchanging the battery is described in the Service Manual Instrument.
Preset Setting
A defined setting status is achieved by pressing the [PRESET] key.
Preset Status:
RF frequency 10 GHz
RF level -20 dBm
Reference frequency internal, adjustment off
Offsets 0
Modulations switched off
Transient-free level setting switched off, level attenuator mode: Auto
Internal level control level Alc: On
User correction level Ucor: Off
LF output switched off
Sweep switched off
List mode switched off
Memory sequence switched off
Suppression of indications system security: unaltered
Protection of calibration data protection lock: unaltered
Settings stored unaltered
Data, lists etc. stored unaltered
IEC-bus address unaltered
All parameters and circuit states, even those of operating modes which are not activated, are preset by
means of Preset. The presettings going beyond the above list can be seen from the menu
representations as of Chapter 4 which each indicate the Preset setting status.
Functional Test
On switching on the instrument and permanently during operation, the SMR carries out a self test. The
ROM contents as well as the battery of the non-volatile RAM are checked. The most important
instrument functions are automatically monitored during operation. If an error is detected, the message
"Err" is displayed in the status line. For further identification of the error, press the [ERROR] key.
Thereupon a description of the error is displayed (cf. Chapter 9, section "Error Messages"). Return to
the menu exited by pressing the [BACK] key. If required, internal test points can be polled by the user
and the results be read out and displayed. Cf. Service Manual Instrument.
Mounting into a 19" Rack
Caution: Ensure free air inlet at the perforation of the side walls and air outlet at the rear of the
The SMR can be mounted into a 19" rack by means of rack adapter ZZA-94 (stock no. 396.4905.00).
The mounting instructions are attached to the adapter.
