This allows the target frequency at the output of a downstream instrument to be entered
in the frequency field. The signal generator changes the RF output frequency according
to the entered offset.
However, the frequency entered and displayed in the "Frequency/Phase" menu of the
"RF/A Mod" function block always corresponds to the RF output frequency. Any fre-
quency offset is not taken into consideration.
The correlation is as follows:
Freq in header = RF output frequency (= Freq in menu) + Freq offset (= Offset in menu)
OVERLOAD
The power of the external signal applied to the RF output is too high. The overload pro-
tection is tripped and the connection between the RF output and attenuator is interrupted.
The overload protection is reset by pressing the RF ON/OFF key. The RF input is acti-
vated when the overload protection is reset.
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 target 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/A Mod" function
block always corresponds to the RF output level. Any level offset is not taken into con-
sideration.
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.
The reference frequency setting is effective for both paths.
BUSY
A setting or calculation is executed.
9.1.2 Status information displayed to the left of the Info line
This chapter gives an overview of the status messages displayed to the left of the Info
line.
REMOTE
The instrument is remote controlled. The keys on the front panel are usable, but all
parameters are in read only mode.
