816 Operating Manual 1403.7458.32 ─ 14
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 fre-
quency is set (sample and hold mode)
ListMode
List mode is active.
The values of the frequency/level pairs in the selected list are set for the chosen dwell
time.
AttFixed
Attenuator fixed mode is active.
The uninterrupted level settings are made in a fixed range without attenuator switching.
The variation range is set automatically when this mode is activated. The range is dis-
played under "Attenuator Fixed Range" in the "Level" dialog.
UCorr
User Correction is active.
The level is corrected by the given values in the selected user correction list. Correc-
tion is performed by the user-defined list values being added to the output level for the
respective RF frequency. With frequencies which are not contained in the list, the level
correction is determined by interpolation of the closest correction values.
OvenCold
The reference oscillator has not yet reached its nominal frequency.
When switching on from the STANDBY mode, the specified frequency accuracy is
reached immediately. If the power switch was switched off, the reference oscillator
needs some warm-up time to reach its nominal frequency. During this period of time,
the output frequency does not yet reach its final value either.
9.2 Error Messages
Messages indicate errors in the instrument. They are displayed in the info line in differ-
ent colors depending on their importance and display duration. Errors (e.g. no calibra-
tion data) are displayed in red, information (e.g. file not found) and warnings in black.
Warnings indicate less significant errors (e.g. the instrument operates outside specified
data).
