BARGRAPH The BARGRAPH MAXHOLD switches on the maxhold display of a single measure-
MAXHOLD ment.
The BARGRAPH MAXHOLD softkey changes the display of the results of the bar
graph measurement such that both the highest level for each detector and the fre-
quency at which it is measured are displayed. The MAX Hold value will not be auto-
matically reset by the instrument until BARGRAPH MAXHOLD is switched off or
until, for example, the test receiver mode is deactivated as a result of switching to
the analyzer.
Thus, you can also trace fluctuating interference signals in the frequency, and the
highest measured value will remain on screen together with the associated fre-
quency.
The softkey is only available in receiver mode.
Remote command:
BARGRAPH The BARGRAPH RESET softkey resets the stored maximum values of the bar
RESET graph measurement.

REF LEVEL
The REF LEVEL COUPLED softkey switches the coupling of the reference level on
COUPLED and off. In addition to the reference level, the mixer level and input attenuation are
coupled with one another.
For the level measurement, the same reference level and input attenuation must be
set for the two diagrams.
The softkey is only available in analyzer mode.
