Change of the following settings:
• coupling (RBW, VBW, SWT)
• reference level, RF attenuation
• start or stop frequency
• output level of tracking generator
• frequency offset of tracking generator
• detector (max. peak, min. peak, sample, etc.)
Change of frequency:
• max. 625 points within the set sweep limits
(corresponds to a doubling of the span)

normalization
• 625 and more extrapolated points within the current
sweep limits (in case of span doubling)
At a reference level (
REF LEVEL
) of -10 dBm and at a tracking generator output
level of the same value the R&S ESU operates without overrange reserve, i.e. the
R&S ESU is in danger of being overloaded if a signal is applied whose amplitude
is higher than the reference line. In this case, either the message
OVLD
for over-
load is displayed in the status line or the display range is exceeded (clipping of the
trace at the upper diagram border = Overrange).
Overloading can be avoided as follows:
• Reducing the output level of the tracking generator (

• Increasing the reference level (
