Instrument Functions: A - L
2.2.2.1 Auto: Best Dynamic Range
This function is automatically activated when
Auto All is selected. Selecting Auto: Best
Dynamic Range
tells the analyzer to choose between swept and FFT analysis, with a
primary goal of optimizing dynamic range. If the dynamic range is very close between
swept and FFT, then it chooses the faster one.
While
Zero Span is selected, this key is grayed out. The status of the FFT & Swept selection
is saved when entering zero span and is restored when leaving zero span.
Key Path:
Auto Couple, FFT & Sweep
Saved State: Saved in instrument state
Remote Command:
[:SENSe]:SWEep:TYPE:AUTO:RULes SPEed|DRANge selects the rules to use when
SWE:TYPE AUTO is selected. This setting, combined with your current analyzer setup, is
used to select either FFT or swept mode.
[:SENSe]:SWEep:TYPE:AUTO:RULes?
Example: SWEep:TYPE AUTO selects the automatic mode.
SWE:TYPE:AUTO:RUL DRAN sets the rules for the auto mode to dynamic
range.
2.2.2.2 Auto: Best Speed
Selecting
Auto: Best Speed tells the analyzer to choose between FFT or swept analysis
based on the fastest analyzer speed. While
Zero Span is selected, this key is grayed out. The
auto-couple settings are kept in memory and are restored whenever leaving
Zero Span.

See “Auto: Best Dynamic Range” on page 59.
Example: SWEep:TYPE AUTO selects the automatic mode.
SWE:TYPE:AUTO:RUL SPE sets the rules for the auto mode to speed
