Putting into Operation R&S SML / R&S SMV03
1090.3123.12 E-6 1.4
RAM With Battery Back-Up
The R&S SML / R&S SMV03 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 user correction of the
level, are stored in the RAM. Further, all data of the calibrations running within the instrument in the R&S SML
/ R&S SMV03 are stored in the RAM (cf. Chapter 4, section "Calibration"). 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.
Preset Setting
A defined setting status is achieved by pressing the [PRESET] key.
Preset Status:
RF frequency 100 MHz
RF level -10 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
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 R&S SML / R&S SMV03 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.
Mounting into a 19" Rack
The R&S SML / R&S SMV03 can be mounted into a 19" rack by means of rack adapter ZZA-211 (stock
no. 1096.3260.00). The mounting instructions are attached to the adapter.
ATTENTION
Risk of damage to the instrument.
Ensure free air inlet at the perforation of the side walls and air outlet at the rear of the
instrument in rack mounting.
Non-observance may cause damage to the instrument.
