Auto.
The Auto setting is an optimized trade-off of the competing performance choices. This setting is the
instrument default from the factory and is part of the ‘Preset’ function.
The table below summarizes the conditions.

Auto -25 dBm Driven by selected span.
If span is greater than the
available acquisition BW,
unit sweeps using 40 MHz
acquisitions. Neutral Swept Speed, Dynamic
Range, Noise Floor
Minimize
Sweep Time -25 dBm Unit uses widest available
acquisition BW for spans
greater than maximum
acquisition BW. Neutral For units equipped with
Option 110, swept update
rate is approximately 3
times faster than Auto.
No effect in units without
Option 110.
Maximize
Dynamic Range -20 dBm Driven by span and
user-selected RBW. For
RBW < 30 kHz, the high
dynamic range 312.5 kHz
path is used regardless of
selected span. Sweeps
are made in 40 MHz
acquisitions. Might result in very slow
sweep speeds in wide
spans when RBW <
30 kHz.
Minimize Noise -25 dBm Same as Auto Gains set to
minimize noise
level. Might result in earlier IF
overload under some
signal conditions.

Reference Tab
The Reference tab enables you to specify the Power Reference parameter. The Power reference parameter
is used to calculate relative values in the Spur table and to calculate relative amplitude limits.
