Status Information R&S SMC100A
1411.4060.32 9.2 E-1
LEVEL OFFSET
A level offset is set.
The level entered and displayed in the Level field takes the offset of any
downstream attenuators/amplifiers into consideration by way of calculation. This
means that with a level offset the level displayed in the header does not correspond
to the level at the RF output, but rather to the level at the output of the downstream
instrument.
This allows the desired level at the output of downstream instruments to be
entered. The signal generator changes the RF output level according to the set
offset.
However, the level entered and displayed in the Level menu of the RF/Ana Mod
function block always corresponds to the RF output level. Any level offset is not
taken into consideration.
The correlation is as follows:
Level in header = RF output level (= Level in menu) + Level offset
EXT REF
An external reference is used.
The external signal with selectable frequency and defined level must be input at the
REF IN connector. It is output at the REF OUT connector.
Status information displayed to the left of the Info line:
REMOTE
The instrument is remote controlled.
The
LOCAL key switches the instrument from remote control to manual control. The
current command must be fully processed before the mode is switched, otherwise
the instrument switches immediately back to remote control.
REM LLO
The instrument is remote controlled.
The instrument can be switched from remote control to manual control by means of
remote control only (e.g. with the Visual Basic command CALL IBLOC
(generator%)); the LOCAL key is disabled. The key is disabled by remote control
with the command LLO.
Status information displayed in the Info line:
RFSweep
LevelSweep
LFSweep
The indicated sweep is enabled.
ALC On/Auto/S&H
The status of the automatic level control is indicated:
- ON = automatic level control permanently on
- Auto = automatic level control is automatically adapted to the
operating states
- S&H = automatic level control off, recalibration of the level whenever
the level or frequency is set (sample and hold mode).
